Currently known only from the Igarapé Castanha, a tributary of the rio Tiquié (itself a tributary of rio Uaupés), upper rio Negro basin, Amazonas state, in Brazil. It was only recorded a little upstream of the indian village of Santa Rosa and other collecting sites downstream the Igarapé Castanha and along the rio Tiquié only revealed its co-mimic, Corydoras tukano, which is not only more distributed but also considerably more abundant than the rare C. desana. The four specimens of Corydoras desana collected between September and November 2006 were schooling along with C. tukano at sandy beaches. The Igarapé Castanha is a meandering river with oxbow lakes, alternating sandy beaches and river terraces, with clear water, but with a considerable amount of suspended sediments (quite distinct from the rio Tiquié, which is a typical black water river at least before its junction with the Igarapé Castanha) (Ref. 138491).
