This species is distinguished by the following characters: pelvic fin rays 11 (rarely 12); pectoral fin rays 13-15; projecting snout, 20-25% HL; no barbel; moderate orbit diameter, 30-33% HL; infraorbital width 13-15% HL; moderately long preopercular supporter, with obtuse angle at rear margin, 3-5% HL; 20-26 gill rakers; ventral striae reaching to ½ distance from pelvic fin bases to periproct; otolith has moderately high predorsal lobe, with colliculi separated, widely placed across collum, terminating at some distance from anterior and posterior rims of otolith; otolith length to height (OL:OH), 1.05-1.1; total colliculum length to pseudocolliculum length (TCL:PCL), 2.4-2.6 (Ref. 98298).
身体非常细长的, 头部低的, 子方骨横切面，宽度在眼窝的前边缘深地大约等宽于。 吻相当长的, 在一个点尖中的终端前面地与突出的超过嘴对于距离些微地少于眼窝的 1/2 直径。 眼窝小的, 子圆形的。 嘴大的﹐侧面的﹐和非常地斜的。 没有触须。 鳞片大而细又裸露的区域具有非常排列成梅花状排列的小又弱的小刺, 那些在胸部，腹面与腋窝的窝上完全圆形。 正好在臀鳍前面的排泄孔而且前面有一个长的发光器官。 二个外部的透镜出现在常数位置, 些微地对于距离被朝腹面中央线进攻超过腹鳍基底的前面的少于在排泄孔正前方的 1/2 眼窩的直徑, 與後面那個，大於先前者.(參考文獻 54421)
