简单描述
型态特徵 | 形态测量图
背棘 (总数): 2; 臀棘 0. Snout short, conical, with a small but stout, distinctly bifid scute at its tip. Chin barbel very short. Underside of the snout and part of the suborbital space without scales; mandibular rami with loose scales along midline of each ramus; pores of the lateralis system indistinct on the head, although a small dark papillae is prominent. Pyloric caeca 17 to 25. Body scales are fairly large and deciduous, with lanceolate spinules arranged in convergent rows. Overall color is swarthy to brownish, the abdominal region bluish black; mouth dusky, gill cavity black except for pale areas ventrally and along medial wall; fins dark brown to brownish black.
吻短的，锥形, 具有一个小的但是在它的顶端矮胖又明显两裂的鳞甲。 下巴触须非常短的。 吻部与眶下空间的部份的下面没有鳞片; 颚骨分支用散落的鳞片沿着每个分支的中线; 侧线系统的孔不明显的在头部上，虽然一个小的深色乳突是突出的。 幽门盲囊 17 到 25. 身体鳞片是非常大而易脱落的,与排列成趋集于一点的列矛尖形的小刺。 整体的色彩是黑黝黝的到褐色的, 腹部的区域蓝黑色的; 嘴暗色的, 鳃腔黑色腹地除了灰白的区域而且沿着中间的墙壁; 鳍深褐色的到深褐色的。
