Anale stekels: 1; Anale zachte stralen: 10 - 11; Wervels: 27. This robust, large-eyed species is distinguished by the following characters: D2 I,11; A 11-12; pectoral-fin rays 19-20; body extensively scaled, with mid-lateral scales extending from just behind pectoral-fin axil to caudal-fin base; most scales are weakly ctenoid; cycloid scales on belly, in first row along dorsal- and anal-fin bases, and in anteriormost lateral row; well developed fifth pelvic-fin ray and is slightly greater in length than second pelvic-fin ray; relatively deep body; first and second dorsal-fin spines are greatly elongated, especially in females; first spine reaching posterior end of second dorsal-fin base in female holotype; first two anal-fin pterygiophores are inserted anterior to first haemal spine (Ref. 94726).
