ABSTRACT

The Villavicencio Region, at the base of the eastern mountain range, harbors an amphibian fauna consisting of three caecilians, 45 frogs, and one salamander. This fauna includes 16 abundant species of frogs and toads that occupy open habitats and which do not invade forested areas of these lowlands. An additional 24 species require moist conditions and occur principally in areas supporting forests. Seven other species are species of the Andean slopes that have their lowest records in the lowlands. This local fauna is enriched in treefrogs and impoverished in terms of centrolenids and leptodactylids relative to the diversities of various amphibian groups in the country as a whole.

Key words. Caecilians, Frogs, Piedmont, Salamanders, Zoogeography.

RESUMEN

En la región de Villavicencio, en la base de la cordillera Oriental, se encuentra una fauna de anfibios que consiste de tres cecilias, 45 ranas y una salamandra. La fauna incluye 16 especies abundantes que ocupan hábitats abiertos y no entran en áreas de bosque. Otras veinticuatro especies requieren condiciones más húmedas y ocupan áreas boscosas. Siete especies pueden establecerse en las laderas andinas, aunque también se encuentran en las tierras bajas. La fauna local es rica en hílidos y pobre en centrolénidos y leptodactylidos con relación a los valores de riqueza y diversidad en otras áreas del país.

INTRODUCTION

For thirty years, field courses of the Universidad Nacional de Colombia have sampled the animal fauna in many parts of the country but relatively little of the accumulated collections has been used in the preparation of scientific reports. One of the general regions visited frequently has been the Villavicencio region. Rarely, collectors have sampled the Andean slopes immediately above a series of towns in the piedmont (Acacias, Cubarral, Cumaral, Guamal, Medina, Paratabueno, Restrepo, San Martín, Santa María, and Villavicencio). There is a frog fauna of the eastern Amazonian slopes of the Andes but the only species of that fauna that will be reported here are those species which have lowland records (below 1000 m) in the region. The frog collections made in the vicinity of Florencia, Caquetá, in 1990 have been reported (Suárez Mayorga, 2000).
Other published reports are those of William Pyburn in the early 1970s in eastern Colombia (Fouquette & Pyburn, 1972, Pyburn, 1973, Pyburn & Fouquette, 1971), the miniature leptodactylids of the genus Pseudopaludicola (Lynch, 1989), some of the frogs of the genus Leptodactylus (Heyer, 1978, 1979, 1994), the few Eleutherodactylus in the region (Lynch, 1994), part of the collections of centrolenids (Ruiz Carranza & Lynch, 1998), all of the caecilians (Lynch, 2000), and all of the gladiator frogs of the Hyla boans group (Lynch & Suárez Mayorga, 2001). Except for these published reports, one essentially must revise old literature (Stebbins & Hendrickson, 1959, Cochran & Goin, 1970) to convince oneself that there is an amphibian fauna there.

Two of the three orders of amphibians (Caudata and Gymnophiona) are represented by one (Bolitoglossa altamazonica) and three species (Potomotyphlus kaupii, Siphonops annulatus¸and Typhlonectes compressicauda), respectively, in the region. Frogs and toads (Anura or Salientia) are well-represented in the region and all eight families of frogs or toads currently recognized and known for the country occur in the region.

As defined here, the Villavicencio region consists of lowlands (below 1000 m) in eastern Boyacá, extreme eastern Cundinamarca, and western Meta. To the south, it touches the Serranía de la Macarena (Meta). This sector shows at least three environmental gradients: (1) a dry to wet gradient, across the lowlands; (2) a gradient from open habitats (some apparently natural, the llanos, and others induced by anthropogenic activities--the clearing of lands for pastures or crops) to wet forested habitats; and (3) an altitudinal gradient (from perhaps 300 m to my upper limit of 1000 m). The last gradient mixes the effect of altitude with the effect of moisture because at higher elevations, the lower night time temperatures provide compensating moisture. The amphibian fauna of the Villavicencio Region extends to the north into Arauca and Casanare as well as into western Venezuela with the addition of very few species. Looking at the subset of species characteristic of open habitats, this fauna “disappears” to the SSW (Suárez Mayorga, 2000).

MATERIALS & METHODS

Although I have examined many additional specimens housed in other institutions, this report concerns only material housed in the amphibian collection of the Instituto de Ciencias Naturales. Approximately 2550 specimens housed in that collection were examined for this study. Actual records are provided in the appendix.

THE AMPHIBIAN FAUNA OF THE VILLAVICENCIO REGION

Order CAUDATA

Family Plethodontidae
This is the only family of salamanders found on the continent but is very poorly-known.

Bolitoglossa altamazonica
This species is widely distributed in the Amazonian lowlands (Brame & Wake, 1963) and there is a suspicion that it is actually a species complex. A description is available in Brame & Wake (1963). In the Villavicencio region, the species appears to be confined to the wettest fringe of the piedmont. Elsewhere in Colombia, the species is known from scattered localities near the frontiers with Brasil and Peru; the record from the Magdalena valley by Brame & Wake (1963) is a mis-identification of another species (A. Acosta, pers. comm.).

Order GYMNOPHIONA

Family Caeciliidae
This family is represented by a good number of species in Colombia, distributed from sea-level to at least 2300 m (Lynch, 2000). Previously, Lynch (2000) used the family-group name Caeciliaidae but he was unaware that the International Commision of Zoological Nomenclature (Anon., 1996) had reversed its earlier decision so as to allow Caeciliidae to refer to caecilians rather than psocopterans (insects). Several species are known for the wetter part of the Amazonian lowlands of Colombia and it is possible that Microcaecilia albiceps extends to the north of the Florencia region along the piedmont.

Siphonops annulatus
This is the only terrestrial caecilian in the region. Nearly all records of S. annulatus for Colombia were reported by Lynch (2000)—the only new records are those from Acacias. The best description available is that of Taylor (1968). As others have noted, unlike most caecilians, S. annulatus seems more tolerant of dry conditions. At Acacias in 2004, the species was common under decomposing trunks of the African oil palm, even in grazed pastures.

Family Typhlonectidae
Two species are known east of the Andes (Lynch, 2000) and both reach the Villavicencio region.

Potomotyphlus kaupii
This aquatic caecilian is expected to occur in all the rivers flowing northeast and southeast from the Andes although there are only five records available (Lynch, 2000, and recent collections from Leticia). The few records probably reflect the difficulties of collecting in rivers and the low frequency of herpetological collections in such habitats. The best description is that by Taylor (1968).

Typhlonectes compressicauda
The only published record was for Leticia (Duellman & Trueb, 1994), where the species is relatively abundant. Recent collections have revealed that the species is found as well near Puerto Gaitán, Meta. This new record suggests that the absence of records is more the result of failure to search for aquatic caecilians than their actual distributions. As an aquatic organism, it is resistant to the vicissitudes of a dry season. Taylor (1968) provides descriptions.

Order ANURA

Family Bufonidae
True toads comprise one of the larger families of frogs and toads in Colombia but are divided more or less into one set centered on the Andean chains and a second set found in the lowlands. The Villavicencio region fauna consists of the second set. Two genera are found there, Bufo with four species, and a single species of Dendrophryniscus.

Bufo glaberrimus
Although found below 1000 m in the region, the species seems more likely a species of the Amazonian slope fauna. The description by Cochran & Goin (1970) is acceptable but they appear to have confused no fewer than three species (Bufo blombergi, B. glaberrimus, and B. guttatus) in their list of specimens examined. East of the Andes in Colombia, there are two species of the Bufo guttatus group--B. glaberrimus of the piedmont (or eastern Andean slopes) and B. guttatus in rocky areas along the eastern border of the country (Amazonas to Vichada). The latter was incorrectly reported as B. anderssoni by Ardila R & Ruiz C (1997) and Ruiz C et al. (1996)—the specimens upon which the reports were made are all juveniles and appear to me indistinguishable from B. guttatus. The report of B. guttatus from just above Villavicencio by Stebbins & Hendrickson (1959) is based on B. glaberrimus. This is an unusual toad in that its tadpoles live in low-gradient streams.

Bufo granulosus
The description by Cochran & Goin (1970) is satisfactory. This is a common toad in areas of intervention and can be found breeding in very small and shallow puddles. It is widely distributed in open habitats over the Caribbean coast and Magdalena valley of Colombia, in the southwestern part of the Maracaibo Basin in Colombia, and across the eastern llanos.

Bufo marinus
This is the largest of the true toads in the region and is most commonly found in towns and associated with human occupation (fincas and haciendas)—it rarely occurs in natural forests. The description by Cochran & Goin (1970) is satisfactory. Although a large species, its tadpoles are very small and easily recognized by the bi-colored tail musculature (brown or black above, cream below).

Bufo “typhonius”
The species found in the Villavicencio region (most localities are along the base of the eastern Cordillera—the species does not extend to the east) is involved in a taxonomic nightmare and may be undescribed (Vélez, 1995). To attach some name, I follow Cochran & Goin (1970), who confused all of the species of this group in Colombia under a single name. The described specimen in Cochran & Goin (1970) is a species found in the west-central part of the Amazon Basin—that species does not come so near the Andes. The best descriptions are those of Stebbins & Hendrickson (1959) and Velez (1995, in an unpublished undergraduate thesis) and her (2000) description of what may be the same toad under the name B. sternostignatus.

Dendrophryniscus minutus
This tiny toad, better known from the Amazon Basin (ICN has records from Amazonas, Putumayo, and Vaupés), occurs in well-forested localities to the immediate SE of Villavicencio. Unlike other toads for the region, this species lacks parotoid glands. The animal is active on the forest floor by day. The description in Duellman (1978) is brief but enables easy recognition; the original description by Andersson (1945) is more detailed but difficult to access.

Family Centrolenidae
Centrolenids require streams for breeding and the streams must be forested. Accordingly, all records are closely associated with the Andean cordillera. The two species known for the Villavicencio region are lowland species, barely occurring above 1000 m.

Cochranella flavopunctata
The best description is that by Lynch & Duellman (1973). The species occurs along the eastern foothills of the Andes in Ecuador and is known from the Colombian departments of Boyacá, Caquetá, and Meta. Males call from the upper surfaces of leaves over streams and egg masses are deposited on the upper surfaces of leaves. The green body with small yellow spots enables rapid recognition of the animal in life. Once preserved, it is most easily separated from the other centrolenid with which it is sympatric by the white peritoneum of the body wall (in Hyalinobatrachium munozorum the parietal peritoneum is transparent enabling a view of the white viscera). This is a microhabitat specialist and seldom collected.

Hyalinobatrachium munozorum
The best description is that by Lynch & Duellman (1973). This species is microsympatric with the former but perhaps does not occur as high on the Andean slopes. The visible white viscera allow rapid identification. Males call from the underside of leaves over streams and deposit their egg masses there. The egg masses are guarded by the male parent. The microhabitat of this species is not visited frequently by collectors.

Family Dendrobatidae
This family has a peculiar distribution within Colombia, largely defined by its reproductive biology. Frogs of this family have terrestrial eggs, normally guarded by the male parent. Upon hatching, in the vast majority of cases, the tadpoles climb upon the back of the male parent, who transports them through the environment, presumably adjusting to conditions of humidity and temperature—ultimately, the parent deposits the back-borne, non-feeding, tadpoles in some body of water, where they assume an exotrophic life. The ecological description for the Villavicencio region is one that is not favorable to this reproductive mode, although to the S and SE, one finds wet tropical forests—accordingly, this family is poorly represented in this region.

Dendrobatids can be recognized readily for having a pair of gland-like pads on the dorsal surface of each digital pad (most evident on the foot). Male parents frequently are found to be transporting their tadpoles on the back.

Colostethus cepedai
The taxonomy of this species remains somewhat clouded for me. Morales (2002) described C. cepedai from Villavicencio based on material collected simultaneously with the type-series of C. juani. This taxon apparently applies to his trilineatus group (defined on the basis of two characters—a basal web between the third and fourth toes of the foot and a pale blotch (not extending onto the posterior surface of the thigh) lateral to the cloaca). No specimen from the Villavicencio region in the ICN collection corresponds to this species but Taran Grant (pers. comm.) has seen records from the Serranía de la Macarena.

Colostethus juani
This species is common in the altered forest fragments immediately adjacent to Villavicencio and its airport. This observation may mean that the species is sufficiently plastic to tolerate human intervention so long as the intervention does not destroy completely the forests. Its toes are unwebbed and it lacks an oblique lateral stripe. A description is available in Morales (1994) and another in Cochran & Goin (1970), the latter under the name C. brunneus.

Colostethus palmatus
This species is well-known biologically (Lüddeke, 2000) from the eastern Andean slope in Cundinamarca but there are populations in the immediate vicinity of Villavicencio (Bosque de Bavaria). Additionally, there are populations assigned tentatively to this species from the other slope of the Cordillera Oriental as well as in wetter parts of the valley of the Rio Magdalena and the Cordillera Central and most northern parts of the Cordillera Occidental. The description by Cochran & Goin (1970) is detailed. This is the only dendrobatid in the region having extensive webbing of the hindfoot. The species is quite sensitive to habitat modifications by man--for many years the populations along the Bogotá—Villavicencio road were silent (extinct?) until the new road was constructed. Then, the species returned to the surviving fragments of the old road. This species is easily recognized in the area for its size and the obvious toe webbing. Its tadpole is large and lacks a pattern.

Colostethus ranoides
This species was described from Villavicencio and the holotype resides in the British Museum (Silverstone, 1971). As described, it has an oblique lateral stripe from the eye to the groin and lacks toe webbing. Nonetheless, in spite of many fieldtrips by the ICN to the Villavicencio region, the species has not reappeared in modern collections. For this reason (actually, negative evidence, which is not evidence of anything), Acosta & Rueda Almonacid (2004) took the position that the species has suffered catastrophic declines and is in urgent need of legal protection. The other two Colostethus remain abundant in the region (in the appropriate microhabitat), so perhaps, this species has been exterminated, inadvertently.

Epipedobates femoralis
Cochran & Goin (1970) reported this species from the wetter parts of the piedmont along the eastern base of the Cordillera Oriental. Their description and that of Silverstone (1976) allow ready recognition of this colorful dendrobatid. Unlike E. hahneli, E. femoralis lacks the pale spot on the underside of the shank (below the knee). Epipedobates femoralis is larger (SVL 20-31.5 mm) than E. hahneli (16.5-25.5 mm). These are active daytime frogs, being seen hopping in the leaf litter, especially during, or the day following, rains.

Epipedobates hahneli
Cochran & Goin (1970) reported the species from the foothills associated with the Macarena massif and provide an acceptable description as did Silverstone (1976). As is the case with most dendrobatids, the distribution of this species closely parallels regions where precipitation exceeds evapotransporation. Another factor perhaps explaining the spotty distribution of E. hahneli in Colombia is that the species appears to exist as local demes, being absent in some sections of the contiguous rainforest and present in others.

Family Hylidae
This is an important family of the lowlands of South America—three of the four subfamilies occur in the continent (Duellman, 2001) and most employ reproductive strategies (aquatic tadpoles) that render them more or less immune to the exigencies of a prolonged dry season. The subfamily Hemiphractinae does not occur below 1000 m in this sector but can be found on the Andean slopes above Villavicencio. At Villavicencio, the subfamily Phyllomedusinae is poorly represented (Phyllomedusa) living in the margins whereas the subfamily Hylinae is well-represented. Such “familiar” genera as Hyla and Phrynohyas have “disappeared with the new classification proposed by Faviovich et al. (2005).

Dendropsophus brevifrons
This small species of the D. parviceps group reaches its northernmost distribution in the Villavicencio region. The description by Duellman & Crump (1974) is detailed. Based on my work in the Leticia area, where the species is abundant, I (Lynch, 2005) classified this as a canopy species, which if true, explains why so few records exist.

Dendropsophus mathiassoni
Cochran & Goin (1970) provide a detailed original description. Adults are very similar to D. microcephalus, a species found west of the Andes and some observers have confused the two species (i.e., Stebbins & Hendrickson, 1959). They have different calls and the tadpoles are easily distinguished. This frog appears to require open situations and accordingly is very common in the transformed habitats along the piedmont.

Dendropsophus minutus
Cochran & Goin (1970) provide a detailed description. There is some question as to what to call these populations. The species is very widely distributed across Amazonian South America and Kaplan (1994) suggested that there was more than one species involved. In the Villavicencio region, this small tree frog with notable white line above its vent is common at pools in pasturelands as well as in pools at the pasture-forest interface. The species breeds in ponds and calls from shrubs.

Hypsiboas boans
Detailed descriptions of the species are available in Cochran & Goin (1970) and Duellman (1970, 2001). The distribution in Colombia was summarized (including all available records) by Lynch & Suárez Mayorga (2001). This is a species breeding in the dry season and using nests constructed by the adult on the mudflats or sandbars of streams and rivers. The species requires forests but is apparently content in gallery forests. Males call from trees but descend to ground-level to construct their nests (and call from ground-level as well).

Hypsiboas crepitans
Detailed descriptions of the species are available in Cochran & Goin (1970) and Duellman (1970, 2001). The distribution in Colombia was summarized (including all available records) by Lynch & Suárez Mayorga (2001). This species breeds in the wet season and uses (around Villavicencio) ponds and puddles, calling from the ground. The species is very adaptable and lives well in the modified pastures.

Hypsiboas lanciformis
Cochran & Goin (1970) provide a detailed description. The species is very adaptable and occurs commonly in sites of severe intervention (it is more rarely observed in native forests). Adults breed in ponds and call from bushes.

Hypsiboas punctatus
Cochran & Goin (1970) provide a detailed description. This species is widely distributed in western Amazonia and seemingly as content in pasturelands near Villavicencio as in natural habitats near Leticia—if anything, it appears to be more common in areas of human intervention. Breeding occurs in ponds and marshes. At night, these frogs call from the ground and show a red coloration dorsally—by day, the same frogs are green above with red spots and a dorsolateral line (red below and yellow above).

Osteocephalus carri New combination
This species is more common on the Andean slopes than in the lowlands but I (and others) have found it to about 700 m in the Acacias-Villavicencio region. By the literature, it is now called Osteocephalus buckley (Trueb & Duellman, 1971) but that synonymy was in error (Karl Jungfer, pers. comm.). I detected the error by study of tadpoles (which differ morphologically and in coloration from those of O. buckleyi) but those results have not been published nor has Jungfer’s validation of the correct name. This species breeds in sluggish streams and requires some measure of native forest. The only available description is that of Hyla carri by Cochran & Goin (1970).

Osteocephalus taurinus
This is a species more typical of the wet rainforests but some records are available from marginal habitats near Leticia. The description by Cochran & Goin (1970) is adequate as is that by Trueb & Duellman (1971) although the latter authors confused several species under this name (three of which live in Colombia). In the Villavicencio region, it is known from gallery forests.

Phyllomedusa hypocondrialis
Cochran & Goin (1970) provide a detailed description. This is a common frog in open sites across northeastern Colombia and is common as well in the pasturelands of western Meta. Adults breed in ponds and encase the eggs in a purse made from leaves suspended over the pond.

Pseudis paradoxa
Cochran & Goin (1970) provide a detailed description of the subspecies found in the Caribbean lowlands—aside from minor differences in color pattern, that description will suffice for samples from the eastern llanos. That subspecies is found throughout the open lowlands of eastern Colombia but the frog is rarely seen because they are shy and aquatic. Breeding occurs in these same ponds and adults aestivate in the soil during the dry season. The tadpoles achieve large sizes in comparison with the adults—hence the trivial name.

Scinax blairi
This species, described by Fouquette & Pyburn (1972) from Guaviare, is present in the Villavivencio region. The available records suggest that the species is rare but I suspect that collectors may have confused it with the very common S. ruber, and neglected to collect it relative to its abundance. All species of this genus are peculiar because the webbing between the first and second toe of the foot is reduced strongly.

Scinax rostratus
A description is available in Duellman (1970). This species is widely distributed in the lowlands of northern and northeastern Colombia but seems incapable of penetrating the forests to the south (there, it is replaced by the Amazonian S. garbei). This is a common species during the wet season and males can be found perched upon tree trunks (head down) calling. Tadpoles are of the pond-type.

Scinax ruber
Cochran & Goin (1970) provide a description. Most people working with lowland South American frogs agree that this is a species complex. In the Villavicencio region, it (or they) is a common frog, especially near human habitations, easily recognized by the black and yellow marbling on the concealed surfaces of the thighs. Breeding occurs in ponds and puddles. It is probable that we are confusing S. ruber with S. x-signatus in the Villavicencio region.

Scinax wandae
Pyburn and Fouquette (1971) named and described this small species of Scinax from the western edge of the Llanos. This is a very common tree frog in ponds in pastures near Villavicencio and its buzz-like call is likely to be mistaken as the call of some insect. The species breeds in ponds in open situations and avoids forests.

Scinax x-signatus
This species is very similar to S. ruber but appears to be present in the region, based on collections of tadpoles.

Sphaenorhynchus lacteus
Cochran & Goin (1970) provide a detailed description of this atypical species of the Villavicencio region (entering only to the SE of the city)-it is more commonly found in floating meadows in Amazonas but occurs as far north as Guainia (Pto. Inirida). Adults breed in pond-type situations but require floating vegetation.

Trachycephalus venulosus
Cochran & Goin (1970) provide a detailed description. This is a common species in lowland Colombia but its obviousness depends upon its breeding season. Normally, it is an occupant of the canopy but descends to ground level to breed at ponds. The warty skin and the habit of producing a sticky leche enable rapid recognition.

Family Leptodactylidae
This is the largest family of frogs and toads in Colombia (and in South America). At present, it is divided into five subfamilies (Frost “2004”), only two of which are represented in this seasonally dry region. The Eleutherodactylinae (or, currently, Brachycephalinae) shares an aversion to dry seasons with the dendrobatids and is poorly represented (a maximum of three species, only one of which might be termed common). The remaining species are of the subfamily Leptodactylinae, most sharing an adaptation (foam nests) that reduces their sensitivity of dry conditions.

Adenomera hylaedactyla
This small terrestrial leptodactyline is easily confused with juvenile Leptodactylus but is generally recognizable due to the pale vertebral stripe on the posterior one-half of the body. Records are few from the region suggesting that this region is near the northern limit of distribution for the species along the piedmont.

Eleutherodactylus frater
This species was described from the Andean slopes above Villavicencio (Werner, 1899) and is common on these slopes. Pyburn & Lynch (1981) re-described it based on material from the Serranía de la Macarena. The species was reported as E. marmoratus by Stebbins & Hendrickson (1959) from just above Villavicencio.

Eleutherodactylus medemi
Lynch (1994) provided a detailed description of this species which lives in the wettest habitat in the Villavicencio region (accordingly, most records are for the lowest Andean slopes just above the lowlands. When the forest has been cleared (as is common in this part of Colombia, this species disappears).

Eleutherodactylus savagei
This species was first described from the foothills of the Serranía de la Macarena (Pyburn & Lynch, 1981) but subsequently found to occupy the eastern Andean slopes of the Cordillera Oriental, where it is more common, rarely descending below 1000 m (Lynch, 1994).

Leptodactylus colombiensis
This species was associated with Andean habitats, to more than 2000 m (Heyer, 1994, who provides a description). Nonetheless, the species appears to be relatively common in the lowlands associated with Villavicencio and there is even a record in eastern Casanare. This is one of two species for the region with obvious fringes on the toes and in which the males have two thumb spines.

Leptodactylus fuscus
This is a common species of open habitats in lowland Colombia (both in the Llanos and the Caribbean lowlands). For descriptions, see Cochran & Goin (1970) and Heyer (1978). A terrestrial frog usually found by day beneath cover. Males build a shallow cavern to receive the eggs (housed in a foam nest) which floods following rains, liberating the tadpoles into shallow ponds in pastures. This is one of two species in the region lacking lateral fringes on the toes and having a pale stripe on the posterior surface of the thighs (also seen in L. mystaceus).

Leptodactylus insularum
Cochran & Goin (1970) provide a description but appear to have confused L. bolivianus and L. insularum (but their description is based on an individual of L. insularum). I employ the taxonomy of W. R. Heyer who has examined the ICN collections and tells me that L. bolivianus, in Colombia, is known only from the Leticia region. This is a medium-sized Leptodactylus with a single pair of dorsolateral folds, lateral fringes on the toes, and a pale mark on the upper lip. Males have two black nuptial spines. The species seems equally at home in open habitats and in forests suffering human intervention. Breeding occurs in ponds with a floating foam nest attended by the female.

Leptodactylus knudseni
Adults are difficult to identify on morphological grounds (Heyer, 1979). Heyer (1979) provides a description. This is the largest Leptodactylus from the Villavicencio region. Historically, a frog called L. pentadactylus was imagined to occupy most wet lowlands of northern South America (Lynch, 1979) but recent work has established that this was a species complex. This species is widely distributed in the lowlands of Amazonia and in the Villavicencio region occurs in the wetter parts of the habitat (in gallery forests or the piedmont). Adults conceal themselves in burrows in the forest but seem prone to emerge especially during heavy rains.

Leptodactylus mystaceus
This is another species of the fuscus group found in the region and unlike the other has one pair of dorsolateral folds (thus resembling juvenile L. insularum but L. insularum has lateral fringes on the toes). This species is rare in the region, perhaps at its northern limit of distribution.

Lithodytes lineatus
Cochran & Goin (1970) provide a description. This species is widely distributed in Amazonas but whose distribution seems closely associated with the Andes (Lynch, 1979). In the Villavicencio region, the species is confined to habitats with a minimum of human intervention and the species is closely associated with nests of the ant genus Atta. That said, the species is commonly found under tree trunks in cleared pastures. In eastern Colombia, the species extends north along the piedmont to Venezuela and is widely distributed in forested regions.

Physalaemus enesefae
Cochran & Goin (1970) provide a description but under the name of Physalaemus cuvieri dunni. The vaquero is a familiar sound after dark in the western llanos. These frogs call from ground level, at the border of puddles and ponds, largely hidden in the grass. Their distinctive call belies the fact that these are small frogs. They appear to be restricted to open habitats--accordingly, they adapt well to human intervention. As is the case with other species of the genus, adults produce a foam-nest which resists desiccation.

Pseudopaludicola boliviana
This is the smallest species of frog to be found in the Villavicencio region (adults do not reach 20 mm SVL) but is common (if easily overlooked) near ponds and puddles in the grasslands. Elsewhere in eastern Colombia, the species seems more at ease in forested situations (Lynch, 1989, Lynch & Vargas, 2000). Although classified as a leptodactyline, frogs of this genus do not produce foam-nests, rather depositing their eggs in ponds and puddles.

To the east of Villavicencio, one finds P. llanera, a slightly larger frog found in open habitats (Lynch, 1989, who provides a description). The two appear to be sympatric in eastern Guainia (Lynch & Vargas, 2000).

Family Microhylidae
This is one of the species-poor families found primarily in the lowlands in Colombia (Lynch, 1998). A single species is known for the Villavicencio region although Ctenophryne geayi should be expected along the piedmont (its type-locality is near the Colombia—Venezuela border and the species is widely distributed in the Amazon Basin).

Ctenophryne geayi
Although this species has not been collected in the Villavicencio region, I include it within the expected fauna. The ICN has records from Caquetá and the Leticia region and the type-locality lies in the piedmont near the Venezuelan border—hence, the species probably occupies the piedmont in eastern Colombia. Burrowing microhylids are not regularly captured during fieldwork, perhaps because collectors find their gaze oriented toward the understory plants or to the surface and vegetation around ponds.

Elachistocleis ovale
This is a common frog (normally found by searching beneath logs) in pastures (both as adults and as tadpoles). The tadpole is a filter-feeder--accordingly, tadpoles are found in ponds (never streams).

Family Pipidae

Pipa pipa
This widely distributed frog of the Amazon Basin is seldom encountered except by deliberate searching. The ICN material was purchased from fishermen in Puerto López and thus probably comes from the Río Metica or small streams entering it.

Family Ranidae
This is a poorly-represented family in the country. Those who subscribe to biogeography fables (stories) assure us that the family is a recent (late Pliocene or Pleistocene) invader of South America—what seems certain is that there are only three native species (Hillis & de Sá, 1988). One occupies the Amazon Basin and can be found at Villavicencio—the others are trans-Andean. All preserved records in Colombian museums were reported by Acosta (2000). A third species (Rana catesbeiana) was unfortunately introduced into Colombia in the early 1990s—to date, it remains a plague in the interandean valleys.

Rana palmipes
This species occupies an immense distribution east of the Andes (Acosta, 2000a). Adults are very closely associated with streams and rivers of low-gradients. The species occupies ponds as well. No new records are available beyond those reported by Acosta (2000a).

DISCUSSION

The known (and anticipated) amphibian fauna of the Villavicencio region consists of one salamander, three caecilians, and 45 (or 46 if Epipedobates hahneli is to be included) frog (and toad) species. If the region is expanded to the south (so as to include the wet forested lowlands to the east, southeast and west of the Serranía de la Macarena, many more “Amazonian” species of frogs enter the fauna.

There is a suite of 16 very common frog and toad species, all confined to lowland situations and all occupying open and transformed habitats. Some of these also occur in forested situations where they are less abundant: Bufo granulosus, B. marinus, Dendropsophus mathiassoni, D. minutus, Elachistocleis ovale, Hypsiboas crepitans, H. lanciformis, H. punctatus, Leptodactylus fuscus, Phyllomedusa hypocondrialis, Physalaemus enesefae, Pseudis paradoxa, Pseudopaludicola boliviana, Scinax rostratus, S. ruber, and S. wandae. This entire suite, perhaps with the exception of Pseudis paradoxa, can be collected/ observed at any locality of the region during the wet season. Two other species are apparently uncommon species of this suite (Scinax blairi and S. x-signatus), at least around Villavicencio. Of this group of 18 species, the best-collected municipalities of Meta are Acacias, Cubarral, Restrepo, and Villavicencio (with 16, 15, 13, and 17 species, respectively, vouchered in the ICN).

There is second set of lowland species usually requiring much more mesic environments (forests). These species are also less frequently encountered, consisting of three caecilians, one salamander, and 19 (or 20) frogs and toads: Potomotyphlus kaupii, Siphonops annulatus, Typhlonectes compressicauda; Bolitoglossa altamazonica; Adenomera hylaedactyla, Cochranella flavopunctata, Colostethus juani, Ctenophryne geayi (expected, not known), Dendrophryniscus minutus, Dendropsophus brevifrons, Eleutherodactylus medemi, Epipedobates femoralis, E. hahneli (assigned with doubt to the Villavicencio region, see below), Hyalinobatrachium munozorum, Hypsiboas boans, Leptodactylus colombiensis, L. insularum, L. knudseni, L. mystaceus, Lithodytes lineatus, Osteocephalus taurinus, Rana palmipes, Sphaenorhynchus lacteus, and Trachycephalus venulosus. At least in the Villavicencio region, the Adenomera, Epipedobates, and certain Leptodactylus are quite rare frogs, perhaps at or near the northern extreme of their distributions. Only three municipalities (of Meta) have substantial collections of these species (Acacias, Restrepo, and Villavicencio) with nine, nine, and twelve species, respectively, vouchered in the ICN collections.

The third component of this local fauna consists of seven species normally occupying the eastern slopes of the Cordillera Oriental but having some locality records below 1000 m: Bufo glaberrimus, B. “typhonius,” Colostethus palmatus, Eleutherodactylus frater, E. savagei, Leptodactylus colombiensis, and Osteocephalus carri. The only species not assigned to any component is the possibly extinct Colostethus ranoides.
Biogeographically, the Serranía de la Macarena is merely an isolated spur of the Cordillera Oriental although many biologists prefer to view (or to imagine) it as the westernmost of the Guayanan tepuis. Some frog collections have been made along the base of the Serranía and provide a strikingly different local fauna than that discussed here. Cochran & Goin (1970) reported the enigmatic microhylid Otophryne and in the ICN collection there are specimens of the Amazonian Hypsiboas geographicus. In the photographic vouchers of some undergraduates from the Universidad de Los Andes (photographs taken at the primatology station on the Río Duda), I was able to identify Chiasmocleis bassleri, Hypsiboas calcaratus, Phyllomedusa tarsius, and P. tomopterna, Amazonian species at their northernmost limits of distribution along the piedmont. This is probably the best explanation for the records of Epipedobates hahneli as well.

If the frog fauna of the Villavicencio region is calculated as 45 species, represented the eight recognized families, what is notable is the unequal distribution of taxa among families (the Centrolenidae, Microhylidae, Pipidae, and Ranidae are very poorly represented [each 2—4% of the fauna] and the Bufonidae and Dendrobatidae only slightly better [each 9—11% of the fauna] whereas the Leptodactylidae [27%] and Hylidae [40%] are well represented). In part, this distribution parallels the relative richnesses of each family for Colombia and for the continent but there are some departures. Lynch (1998) argued that five families were diverse within Colombia (Bufonidae, Centrolenidae, Dendrobatidae, Hylidae, and Leptodactylidae) and that remains the case (Acosta’s [2000b] listing yields 10%, 11%, 11%, 23% and 41%, respectively of the country’s frog fauna in these five families) . However, the diversities of four of these (all except Hylidae) are embedded in the Andean fauna. In the case of the leptodactylids, Eleutherodactylus (and its generic relatives) is predominantly Andean and the subfamily Leptodactylinae is predominantly lowland. The fauna in the Villavicencio region partially reflects these generalizations (the Hylidae and Leptodactylidae are dominant) but the order of importance of the two dominant families is reversed (hylids are “enriched” and leptodactylids are “impoverished” in the Villavicencio fauna). This enrichment and impoverishment are certainly a consequence of the relative “dryness” (not in terms of gross precipitation but rather its distribution across the year) of the Villavicencio Region reducing the likelihood of survivorship for reproductive modes requiring continuous wet conditions. Amphibians with direct development (eleutherodactyline leptodactylids and plethodontid salamanders fare especially badly) as do centrolenids and dendrobatids.

ACKNOWLEDGMENTS

Andrés Acosta was generous with his unpublished results of his study of Bolitoglossa and Natalia Carrillo, David Sánchez, and Adriana Téllez aided me in checking databanks of the Instituto. I have benefited from discussions with colleagues (Taran Grant, W. Ronald Heyer, Karl Jungfer) concerning some taxonomic problems associated with this local fauna. My fieldwork in the region, off and on during the past 38 years, profited from the collaboration of Cristina Ardila, Taran Grant, Federico Medem (q.e.p.d.), Juan Renjifo, Pedro M. Ruiz (q.e.p.d.), and David Sánchez.

Appendix (Specimens examined)

This includes all specimens examined with the exception of records published by Acosta (2000a), Lynch (2000), and Lynch & Suárez Mayorga (2001), which need not be repeated, so as to document this fauna and reduce the likelihood of unnecessary additional collections.
