Seven branchiostegal rays. Head notably large and broad; preopercle and suborbital bones deep and large, opercle commensurately small; orbit small, 19%-30% HL, diameter much less than broad interorbital; snout high, slightly projecting beyond mouth. Mental barbel small, 10% or less of HL. Gill opening wide, extending forward to below hind end of maxilla; gill membranes loosely and narrowly attached to isthmus. Gill rakers usually 16-17 on inner series of 1st arch. Teeth small, close-set, in narrow tapered band on premaxilla, uniserial on dentary. Scales with numerous small, awl-shaped spinules; no reticulations on anterior field; lateral line scales absent, a series of dark papillae in their place. Vent about halfway between pelvic fin insertion and anal fin origin (usually closer to pelvic insertion), surrounded by a black, oval to teardrop-shaped naked area and preceded by a small, round dermal window of light organ between pelvic fin bases. Pyloric caeca short, 22-24. Color black to dark brown overall (Ref. 54421).
七个鳃条骨。 头部特别地大而宽的; 前鳃盖骨与眶下骨深的而且大的, 鳃盖同量小; 眼窝小的, 19%-30% HL, 直径远小于宽的眼间骨; 吻高的, 些微突出超过嘴。 神经触须小的, HL 的 10% 以内。 鳃裂宽的, 在颚骨的后部末端之下向前延伸到; 鳃膜松弛地而且狭窄地依附于峡部了。 鳃耙通常 16-17 在内部的成列第一上成弓形弯曲。 齿小的, 靠拢在一起, 在前颌骨上的狭窄被成锥形的条纹中, 排成一列的在齿骨上。 鳞片有很多的小, 锥子-形状的小刺; 没有在前面的范围上的网眼; 侧線鱗片不存在, 在他們的地方中的一系列的深色乳突。 排洩孔大約在腹鰭嵌入與臀鰭起源 (通常更靠近腹鰭嵌入) 之間的中點,被黑色包圍了, 橢圓形對淚滴-形狀的裸露區而且前面有在腹鰭基底之間的一個發光器的小又圓皮窗。 幽門盲囊短, 22-24. 色彩黑色到深褐色的整體.(參考文獻 54421)
