Abstract

ACOSTA-GALVIS, Andrés R.  and  PINZON, Adrián. A new nurse frog (Anura: Dendrobatidae) from the cloud forests of the Orinoco basin of Colombia. Biota colombiana [online]. 2018, vol.19, suppl.1, pp.160-190. ISSN 0124-5376.  https://doi.org/10.21068/c2018.v19s1a12.

A new species of nurse frog is described from the Andean foothills in the department of Boyacá and associated Orinoco River basin in Colombia. This species has a morphological similarity to Hyloxalus picachos, which inhabits the Andean foothills in the department of Caquetá but differs due to the presence of an oblique lateral band that extends to the snout, in addition to its chromatic pattern of the iris in life. We describe the ontogenetic change of its larval stages along with its vocalizations, which are composed of simple notes, with a vocalization rate of 124 notes per minute and spectral structure consisting of 5 harmonics with a dominant frequency between 4213.3 and 5828.2 Hz. With the description of this new species, 23 species are recognized for this genus in Colombia.
