Diagnosis. This new species belong to the genus Niophis Bates, 1867 according to the following diagnostic characters: maxillary palpi clearly longer than labials ones, antennae with 12 segments in both sexes, mesosternal process wide and notched, acuminate elytral apex (as in Niophis bucki Martins & Monné, 1973 ). It has some unique characters: rugose integument of the pronotum with three elevations; prosternal process wide and notched at apex. In French Guiana, the only known species of Niophis was N. coptorhina Bates, 1867 ( Fig. 14–15 ; 18 ), type-species of the genus. The new species can be readily distinguished by the shape of the elytral apex, its darker body integument and the color of the legs.

Description. Male ( Fig. 12 ). General aspect slender, integument of head and prothorax dark-brown; antennae, palpi, elytra and tibiae castaneous; femora yellowish.
