Abstract

GONZALEZ, VICTOR H.  and  GIRALDO, CATALINA. NEW ANDEAN BEE SPECIES OF CHILICOLA SPINOLA (HYMENOPTERA: COLLETIDAE, XEROMELISSINAE) WITH NOTES ON THEIR BIOLOGY. Caldasia [online]. 2009, vol.31, n.1, pp.145-154. ISSN 0366-5232.

We describe and illustrate three new bee species of the genus Chilicola Spinola that occur at high altitudes in the Eastern Andes of Colombia: C. (Anoediscelis) paramoides Gonzalez sp. nov., C. (Hylaeosoma) bochica Gonzalez sp. nov., and C. (Oroediscelis) deborahae Gonzalez sp. nov. We also provide biological notes and discuss the phylogenetic relationships of C. deborahae; nests of this species were found inside dry flower stems of Espeletia argentea Humb. & Bonpl. (Asteraceae) and a palynological analysis showed that 80 % of the pollen grains found in brood cells belonged to Arcytophyllum aff. nitidum and A. muticum (Rubiaceae). The ichneumonid wasp Grotea sp. is also recorded parasitizing brood cells of C. deborahae.

Keywords : Apoidea; Colombia; Grotea; Páramo; Systematics.
