Type locality: “Taracuá, Río Uaupés [ Estado do Amazonas ,] Brazil ”. Distribution: Reported from the foothills of Cerros Duida and Marahuaka, two neighboring tepuis in Amazonas state . Remarks: Considered herein under one putative species name are all reports of Allobates brunneus and A. marchesianus from Venezuela , until the proper identity of such populations is resolved. They are considered aff. marchesianus rather than aff. brunneus as the marchesianus type locality is closer to the Venezuelan southern border and the possibility of its presence is still likely. Allobates brunneus is certainly not present in Venezuela , as its type locality lies south of the Amazon and, though similar, the Venezuelan material does not fall into the recent redescription of A. brunneus from its type locality (Lima et al. 2009).
