简单描述

背棘 (总数) : 0; 臀棘: 0; 臀鳍软条: 20 - 22. Body slender, oval in cross-section. Snout long and pointed; maxilla short, tip bluntly rounded, not reaching to front border of pre-operculum, not projecting beyond tip of second supra-maxilla; teeth in jaws minute or absent. gill rakers long and slender, absent on face of third epibranchial. Dorsal fin origin at about midpoint of body; anal fin origin under last dorsal fin ray (Ref. 189). Olive above, silvery on sides and below. Snout blackish above. Fins pale orange; caudal rays blackish at tips (Ref. 37032).
身体细长又椭圆形的横切面。 吻长而尖的; 颚骨短, 顶端钝地圆的,不延伸到前鳃盖的前缘, 不是突出超过第二个上颚骨的顶端; 颚中的牙齿细小或不存在。 鳃耙长且细的, 在第三个上鳃骨的面貌上不存在。 背鳍起点在大约身体中央; 在最后的背鳍鳍条下面的臀鳍起源.(参考文献 189) 橄榄色上方, 银色的在侧边以下上。 吻黑色的上方。 鳍淡橘色; 尾部的鳍条黑色的在顶端.(参考文献 37032)
Occurs in middle and upper reaches of rivers. The numerous and rather long gillrakers armed with fine setae, together with the very long and highly coiled gut suggest a microplanktonic diet. More data needed.
出现于河的中上游。 被覆细毛的很多而相当长的鳃耙, 伴随着非常长又高度盘绕的消化道意味着吃小浮游生物。 需要更多的资料。
