Abstract

The genus Osteocephalus Steindachner, 1862, is currently composed of 24 species, of which 11 occur in Brazil. Here, we present the second record of the recently described tree frog, Osteocephalus castaneicola Moravec et al. (2009) to Brazil, as well as the first state record to Rondonia. We also present comments on its geographical distribution, presenting an updated geographical distribution map.

Highlights

Comprised within the O. planiceps group, is the recently described tree frog Osteocephalus castaneicola Moravec, Aparicio, Guerrero-Reinhard, Calderón, Jungfer & Gvoždík, 2009, which inhabits primary pluvial forests of solid ground with tall trees of 25–35 meters
The species can be distinguished from its congeners based on the lack of vocal fends, canthus rostralis distinct, angular, distinctly curved medially; loreal region concave, a narrow dark line along the mandible; iris bicolored with a dark horizontal stripe, golden above, bronze below, both parts with fine dark reticulate to radiate lines and other characters that are shown in Moravec et al (2009)
O. castaneicola differs from O. leprieurii by having a narrow dark line along the mandible (Figure 1B), absent in O. leprieurii and by having the iris bicolored with a dark horizontal stripe, golden above, bronze below, both parts with fine dark reticulate to radiate lines (Figure 1A and Figure 2A), iris with dark vermiculation in O. leprieurii (Moravec et al, 2009).Osteocephalus castaneicola is currently registered in Bolivia to the regions of San Antonio de Filadelfia, Província de Manuripi, Pando Department (11°18′ S, 67°23′ W; ca. 200 m a.s.l.), San Antonio del Matti, Pando Department (11°30’S, 68°53’W; ca. 270 m a.s.l.), El Tigre, La Paz Department (11°58′ S, 68°00′ W; ca. 122 m a.s.l.)
