This species is characterized by the following: body depth 51.5-58.3; sexual dimorphism

in interorbital width, in specimens approximately 6.0 cm SL, males 4.1-7.9, females 3.2-5.0; first dorsal-fin ray isometric relative to SL, with distinct membranous structure confined to tip. Pectoral fin count at the ocular side 10-13, blind side 8-11. The membranous structure at the tip of the first dorsal fin resembles a small fish or crustacean (possibly a small hippolytid shrimp), authors called the ray the illicium and the structure at the tip as the esca (Ref. 57759).
