Several specimens of a new Sternopygidae, Japigny kirschbaum (Gymnotiformes), were caught in three rivers of French Guiana (Approuague, Mana, Maroni). This species, characterized by alternating large wide dark and vertical bands on the whole body and a scapular foramen, is considered as belonging to a new genus in the Eigenmanninae subfamily. As the other genus of this subfamily (Archolaemus, Distocyclus, Eigenmannia and Rhabdolichops) it has three radials, the third resulting from the fusion of radials 3 and 4; but it differs from the other in having 14-15 precaudal vertebrae versus 11-14, and a lower number of anal fin rays (132-164 versus 160-260). This new species also have a short snout with a subterminal mouth.
