Dung beetles of the tribe Phanaeini (Coleoptera: Scarabaeidade: Scarabaeinae) from Roraima state, Northern Brazil: checklist and key to species Biota Neotropica
Pacheco,Thaynara L.; Vaz-de-Mello,Fernando Z..
Phanaeini comprises about 160 species in 12 genera restricted to the Americas. Since the diversity of this tribe remains little known in several regions of Brazil, this study presents a guide to its 13 species with presence in the biologically rich and largely unexplored state of Roraima: Coprophanaeus (Coprophanaeus) abas (MacLeay, 1819), C.

Lebiasina yepezi, a new Lebiasininae (Characiformes: Lebiasinidae) from the Serra Parima-Tapirapecó mountains Neotropical Ichthyology
Netto-Ferreira,André L.; Oyakawa,Osvaldo T.; Zuanon,Jansen; Nolasco,José C..
Lebiasina yepezi, a new Lebiasininae with a conspicuous color pattern, is described. The new species is endemic of the headwaters of the rio Negro, rio Branco, and rio Orinoco in the Serra Parima-Tapirapecó Mountains, at the border of Brazil and Venezuela. The new species is readily distinguished from all other Lebiasininae by the presence of four black longitudinal stripes on the trunk, and the triangular shaped dorsal surface of the mesethmoid, lacking lateral projections. The unusual color pattern is contrasted with those of other lebiasinin, as well as members of the pyrrhulinin genus Nannostomus. A close relationship between Lebiasina yepezi and the Gran Sabana (Venezuela) species is suggested based in color pattern features. The present contribution...
