Abstract

A new epigonid fish, Epigonus carbonarius, is described on the basis of four specimens (50.8–95.3 mm standard length) collected from off Nuku Hiva Island, Marquesas Islands. This species belongs to the Epigonus oligolepis group, redefined in this study. It is distinguished from the three recognized species of the group by the following combination of characters: a small number of total gill rakers (21–23) and pyloric caeca (6), presence of lingual teeth, and absence of teeth from posterior part of vomer. A key to the species in the E. oligolepis group is provided.
