This species is distinguished from its congeners by the following set of characters: 11-15 long gill rakers long on anterior gill arch; pectoral-fin rays 13-17, preanal length 49.5-60 % of SL, anterior anal fin ray is below dorsal fin ray nos. 14-19; dorsal fin orgin above vertebra nos. 18-22; precaudal vertebrae 26-30; absence of black pigmentation laterally in roof of mouth (Ref. 105129, 128809).
A rare species (Ref.34024). All six specimens collected were caught in bottom fishing gear. Presence of a penis and spermatozoans arranged in spermatophores (Nielsen 1974, Ref. 40903:182) indicate interior fertilization. The eggs were up to 0.7 mm in diameter, but embryos were not observed (Ref. 105129).
