Amphibians and reptiles from a protected area in western Brazilian Amazonia (Reserva Extrativista do Baixo Juruá) Moraes, Leandro João Carneiro de Lima Rainha, Raíssa do Nascimento Werneck, Fernanda de Pinho Oliveira, Alan Filipe de Souza Gascon, Claude Carvalho, Vinícius Tadeu de Papéis Avulsos de Zoologia 2022 2022-10-04 62 1 34 52V5R 449234 (Cope, 1874) NFF Cope 1874 [94,504,1146,1171] Amphibia Craugastoridae Strabomantis Animalia Anura 23 24 Chordata species sulcatus    ( Fig. 5A) This species is the most widespread in the genus  StrabomantisPeters, 1863, which is more diverse in upland areas of the Andean mountain range ( Lynch, 1997; Hedges et al.,2008). This record represents an extension of its distribution range, ca. 400 kmeast of the nearest known locality of occurrence ( see Lynch, 1997). As  S. sulcatusis the only species of the genus widely distributed in lowland Amazonia, this record also expands the known distribution for the genus  Strabomantis( Hedges et al.,2008). Based on the fact that  Strabomantisspeciesare rarely reported for Brazilian Amazonia, are quite similar considering external morphology, and we still have little knowledge on the genetic variation within  S. sulcatus,other species could likely be masqueraded under this name across lowland Amazonia.
