简单描述
型态特徵 | 形态测量图
臀鳍软条: 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).
有别于它的同类前颌骨的藉由有齿手臂大约 1.6-1.9 高度向上突起 (vs.1.5个或更多比较两倍那高度), 与下列的组合特征: 在眼窝的后半段的方骨-颚骨的关节; 嘴 hypognathous; 于大约瞳孔的前缘的颚骨的后缘, 在泪骨的后缘之间与前半部的眶下 2; U 字形的动脉刺骨的背部 hypohyal; 3个前背骨; 在第一背鳍支鳍骨上的一根额外的棘; 在背鳍的 8个 trisegmented 支鳍骨; 第三或第 4根背鳍棘最长的; 臀鳍起源些微地在背鳍的有鳍条的部分的起源后面; 胸鳍与相似长度，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)
