简单描述
型态特徵 | 形态测量图
脊椎骨: 34. Distinguished by the following combination of apparently apomorphic characters: posttemporal bone is absent; extrascapular reduced to a bony latero-sensory canal; epioccipital bridge absent; parietal branch of the supraorbital latero-sensory canal restricted to the frontal bone; supraorbitals absent; medial process on rib of fifth vertebral centrum present as a simple bony spine; a well-defined foramen is present on the posterior region of the medial lamina of the coracoid; fifteen or more dorsal-fin rays present; lateral line incomplete; discrete bands or spots absent, except for a diffuse humeral blotch; origin of the anal-fin base located slightly posterior to or in advance of a vertical line drawn from the posterior termination of the dorsal fin; teeth of all jaw bones conical; body slab sided, relatively short; the anterior portion of pterotic latero-sensory canal does not enter the sphenotic; sphenotic bone, state 0 = sphenotic separated from the posttemporal fossa by presence of an articulation of the parietal and pterotic, state 1, sphenotic enlarged posteriorly and forming a part of the anterior border of the posttemporal fossa; circuli are present on the posterior or apical field of the lateral body scales (Ref. 34069).
区别的特征为显然地 apomorphic 的下列组合特征了: 后颞骨不存在; 外肩胛骨缩小成多骨的 latero了-知觉管; epioccipital 桥不存在; 眶上 latero 的腔壁分支-知觉管局限于前的硬骨了; 眶上的不存在; 在第五个椎骨的椎体的肋骨上的中间的突起呈现成一根单一的多骨棘; 一很清晰孔是位于鸟喙骨的中间薄板的后面的区域之上; 十五个或更多背鳍鳍条呈现; 侧线不完全的; 不连续的条纹或斑点不存在, 除了一个扩散的肩部斑块; 些微地被设置的臀鳍起点基底后面或来自背鳍的后面的终止的在一條垂直的線前面; 所有頜硬骨的齒錐形; 身體平板袒護, 相當短的; pterotic latero 的前部-知覺管不會進入蝶骨; 蝶骨硬骨 , 與後顳窩分開的州 0= 蝶骨被有頂骨的一個關節與 pterotic ，州 1, 蝶骨在後部地增大了而且形成一個後顳窩的前緣的部份; circuli 在後面的或側面身體鱗片的頂上野外採集上出現。 (參考文獻 34069)
