Abstract
The eelpout Leucogrammolycus brychios gen. et sp. nov., is described from nine specimens, five males (92–198 mm SL) and four females (99–205 mm SL), collected from off Rio de Janeiro state, southeastern Brazil, at depths from 536 to 632 m. It is mainly characterized by the following combination of characters: vertebrae 23–26 + 62–66 = 85–92; first anal-fin pterygiophore associated with first or second caudal vertebrae; scales absent; lateral line with mediolateral and ventral branches; upper lip broadly adnate to snout tip; gill slit not reaching ventrally to opposite lower end of pectoral-fin base; pelvic-fin rays 2; head pores relatively few, small, rounded; and whitish mid-body stripe forming a chevron on top of snout.
