Hemipsilichthys nimius is a species of catfish belonging to the family Loricariidae. The species is presently only known from two small rivers in Rio de Janeiro State, Brazil: the Perequê-Açu and the Taquari.
This is a fairly typical loricariid with a broad head and large mouth used for adhesion to rocks in fast-flowing water. Colouring is generally pale brown with darker blotches with standard length up to 105 mm. It can be distinguished from all its congeners by the anatomy of the dorsal fin: eight branched rays are present instead of seven and there is a membrane connecting the last ray to the back of the fish.
