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 mouth isognathous or prognathous (vs. hypognathous); infraorbital 2 rectangular, completely serrated ventrally (vs. irregularly shaped, smooth or partially serrated ventrally); palatine with long dentigerous process (vs. short dentigerous process); dentigerous arm of premaxilla about 2.5 times height of ascending process (vs. about 2 times or less that height); small process for insertion of ligamentum primordium on maxilla; long coronoid process, reaching posteriorly the level of the posterior border of dentary (vs. not reaching posterior border of dentary); long anguloarticular bone, with well-developed, posterodorsally directed postarticular process and mandibular sensory canal completely enclosed in bone, hyoid artery in a groove on posterior surface of dorsal hypohyal ( vs. hyoid artery piercing dorsal hypohyal); dorsal border of anterior ceratohyal only smoothly concave. Differs further by the following combination of characters: quadrate-mandibular articulation just behind orbit; posterior border of maxilla reaching middle of orbit or further backwards, at posterior half of infraorbital 2 or further backwards; 3 predorsal bones; one supernumerary spine on first dorsal pterygiophore (rarely none); 3rd or 4th dorsal fin spine the longest; 7-9 trisegmented pterygiophores in dorsal fin; upper jaw length 130-160% snout length and 35-45% HL; head length 30-38% SL; pectoral and pelvic fins of similar length, being 45-60% HL and 55-75% body depth; 14-17 pectoral fin rays; 8-11 anal fin rays; 45-49 caudal fin rays; procurrent spur present (Ref. 55324).
有别于嘴巴 isognathous 的它的同类或下巴突出的;(vs. hypognathous) 眶下的 2 矩形的, 完全地腹地锯齿状的;(vs. 形状不规则的, 平滑的或部份地腹地锯齿状的) 颚骨有长的齿状突起;(vs. 短的齿状突起) 前颌骨的有齿手臂大约 2.5个次高度向上突起;(vs. 大约两倍以内那高度) 为在颚骨上的 ligamentum 原基的嵌入的小突起; 长的下颚齿骨冠突, 在后部地达到齿骨的后缘的水平;(vs. 不达到的齿骨的后缘) 长的 anguloarticular 硬骨,有发展良好的,背部後方地完全地直接的 postarticular 突起與顎骨知覺管隔絕於硬骨中, U 字形的在凹槽背部 hypohyal 的在後部表面的動脈;( vs. U 字形的動脈刺骨的背部 hypohyal) 前面角舌骨的背部邊緣只有平滑地凹曲。 在組合特徵之後不同進一步藉由: 方骨-顎骨的關節在眼窩正後方; 顎骨的後緣達到眼窩的中央或進一步向後, 在後半段眶下的 2 或進一步向後; 3個前背骨; 在第一背鰭支鰭骨上的一根額外的棘;(很少地沒有) 第三或第 4根背鰭棘最長的; 在背鰭的 7-9個 trisegmented 支鰭骨; 上頜長度 130-160% 吻的長度與 35-45% HL; 頭長 30-38% SL; 胸鰭與相似長度,存在 45-60% HL 與 55-75% 體高的腹鰭; 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)
