臀鰭軟條: 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).
有別於它的同類前頜骨的藉由有齒手臂大約 1.6-1.9 高度向上突起 (vs.1.5個或更多比較兩倍那高度), 與下列的組合特徵: 在眼窩的後半段的方骨-顎骨的關節; 嘴 hypognathous; 於大約瞳孔的前緣的顎骨的後緣, 在淚骨的後緣之間與前半部的眶下 2; U 字形的動脈刺骨的背部 hypohyal; 3個前背骨; 在第一背鰭支鰭骨上的一根額外的棘; 在背鰭的 8個 trisegmented 支鰭骨; 第三或第 4根背鰭棘最長的; 臀鰭起源些微地在背鰭的有鰭條的部分的起源後面; 胸鰭與相似長度，存在 60-75% HL 與 70-110% 體高的腹鰭; 15-16個胸鰭鰭條; 8-11個臀鰭棘條; 45-49個尾鰭鰭條.(參考文獻 55324)
