臀鰭軟條: 8 - 11. Distinguished from its congeners by possessing large coronomeckelian bone and dentigerous arm of premaxilla about 1.5 times the height of ascending process (vs. small coronomeckelian bone and dentigerous arm of premaxilla about 2 times or more the height of ascending process), and the following combination of characters: quadrate-mandibular articulation at anterior half of orbit; mouth hypognathous; posterior border of maxilla at anterior border of orbit or placed anterior to it, generally not beyond posterior border of lachrymal; hyoid artery piercing dorsal hypohyal; 3 predorsal bones; one super-numerary spine on first dorsal pterygiophore (rarely none); 3rd or 4th dorsal fin spine the longest; 7-8 trisegmented pterygiophores in dorsal fin; upper jaw length 90-120% snout length and 28-36% HL; head length 24-33% SL; length of pectoral and pelvic fins 48-75% HL; 50-80% body depth; 14-17 pectoral fin rays; 8-11 anal fin rays; 45-49 caudal fin rays; procurrent spur present (Ref. 55324).
與它的同類區分藉由持有大的 coronomeckelian 硬骨與前頜骨的有齒手臂大約 1.5 倍於高度向上突起 (vs. 小的 coronomeckelian 硬骨與前頜骨的有齒手臂大約兩倍或更多高度向上突起), 與下列的組合特徵: 在前半部的眼窩方骨-顎骨的關節; 嘴 hypognathous; 在眼窩的前緣顎骨的後緣或放置位於它前, 通常不超過淚骨的後緣; 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超級-數目的棘;(很少地沒有) 第三或第 4根背鰭棘最長的; 在背鰭的 7-8 trisegmented 支鰭骨; 上頜長度 90-120% 吻的長度與 28-36% HL; 頭長 24-33% SL; 胸鰭與腹鰭 48-75% HL 的長度; 50-80% 體高; 14-17個胸鰭鰭條; 8-11個臀鰭棘條; 45-49個尾鰭鰭條; 前流的馬刺呈現。 (參考文獻 55324)
