Afterflossenweichstrahlen: 8 - 11. Differs from its congeners by the dentigerous arm of premaxilla about 1.6-1.9 the height of ascending process (vs. 1.5 or more than 2 times that height), and the following combination of characters: quadrate-mandibular articulation at posterior half of orbit; mouth hypognathous; posterior border of maxilla at about anterior border of pupil, between the posterior border of lachrymal and anterior half of the infraorbital 2; hyoid artery piercing dorsal hypohyal; 3 predorsal bones; one supernumerary spine on first dorsal pterygiophore; 8 trisegmented pterygiophores in dorsal fin; 3rd or 4th dorsal fin spine the longest; anal fin origin slightly behind the origin of rayed portion of dorsal fin; pectoral and pelvic fins of similar length, being 60-75% HL and 70-110% body depth; 15-16 pectoral fin rays; 8-11 anal fin rays; 45-49 caudal fin rays (Ref. 55324).
