Abstract

Hypostomus melanephelis, new species, is described from the rio Tapajós basin, Pará State, Brazil. It is distinguished from all congeners by having conspicuous, roundish and tiny set of dark spots, abdominal region mostly naked, a depressed head, keels along dorsal, mid-dorsal and median lateral series of plates, and a caudal fin usually without spots. It is only known from the type-locality at the rio Tapajós, just downstream of the mouth of the rio Jamanxim. © 2015 by Verlag Dr. Friedrich Pfeil, München, Germany.
