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.

I disagree with the assessment of the conservation status, that should be Data Deficient (DD). I don't believe it's reasonable to state that it's of Least Concern (LC) given what was already known about the type locality at the time of collection.
