Abstract
It is argued that the catfish described by MEES (1974) as representing a new genus and a new
species of the Auchenipteridae : Tocantinsia depressa, is conspecific with Glanidium piresi A. DE
MIRANDA RIBEIRO (1920) and that consequently the former is a junior synonym of the latter.
However, the species does not belong in the genus Glanidium, being sufficiently distinct from all other
Auchenipteridae to be retained in the separate genus Tocantinsia. Therefore, its correct name is Tocantinsia piresi (A. DE MIRANDA RIBEIRO).
