A new Corydoras Lacépède, 1803 (Siluriformes: Callichthyidae) from the rio Araguaia basin, Brazil, with comments about Corydoras araguaiaensis Sands, 1990

Luiz Fernando Caserta Tencatt and Marcelo Ribeiro de Britto

Abstract
A new species of Corydoras is described from the rio Araguaia basin, Goiás, Brazil. The new species can be distinguished from its congeners by presenting the following features: infraorbital 1 with very large ventral laminar expansion; infraorbital 2 contacting compound pterotic; flanks densely covered by irregular black spots; and ventral surface of trunk densely covered by coalescent relatively well-developed platelets. It is also discussed the possibility that C. araguaiaensis comprehends a complex of species.

Die neue Art Corydoras eversi ist passenderweise Hans-Georg Evers gewidmet. Bisher war die Art als Corydoras sp. "Guarana" oder C 65 bekannt.
