The metamorphosed female of this species is distinguished from its congeners by the following set of characters: illicium is relatively short (100-110% SL); with an enlarged non-light-bearing secondary esca approximately 75% from the insertion of the illicium, scarcely covered in fine filaments concentrated at the base and tip of the appendage; dentary teeth are moderate (longest tooth 3.8% SL), arranged in approximately three distinct longitudinal series with numerous additional teeth scattered between rows; the longest caudal-fin ray 35.8% SL (Ref. 131311).
