Abstract

ACOSTA-GALVIS, Andrés R.. A new frog with green bones of the genus Scinax (Anura: Hylidae), associated with the sub-Andean forests of the Magdalena River basin, Colombia. Biota colombiana [online]. 2018, vol.19, suppl.1, pp.131-159. ISSN 0124-5376.  https://doi.org/10.21068/c2018.v19s1a11.

As a result of the exploration of post-conflict areas in the Colombia BIO project, a new species of green bones frog of the genus Scinax, assignable to the clade Scinax ruber, is described. The species is endemic to the peripheral sub-Andean forests of the middle Magdalena valley in Colombia. This biological entity was previously identified in the scientific literature as Scinax “A”. The new species is recognizable by its average size 28.6-31.1 mm, chromatic pattern and its particular mating call that is similar to the sound of a goat bleating; each vocalization has a duration of 0.21-0.47 s, with a dominant frequency between 2184-3218 Hz.; its larval characteristics were evaluated, which altogether made it possible to clearly differentiate it from other species in the genus in the trans-Andean region of Colombia. With the description of this species, 18 frogs of the genus Scinax are currently recognized in the Colombian territory.
