背鰭 (合計) : 76 - 79; 臀鰭: 60 - 67; 脊つい: 40 - 41. The species is distinguished by the following: Vertebrae 11+29-30=40-41, dorsal fin rays 76-79, anal fin rays 60-67; small eyes (1.6-2.1% SL); outer pseudoclasper moderately large, wing- shaped, slightly bent outwards; inner pseudoclasper almost free, bifurcate, with stout hook-like anterior branch and broad flap-like posterior branch; scale patch on cheek with 6-7 rows of small scales on upper cheek, 2 large scales on operculum above opercular spine; head massive, broad; otolith length to height ratio 2.1. This is the only species of the genus which combines small eyes (about 2.1% SL) with presence of scales on the operculum (Ref. 57884).
