背棘 (总数) : 0; 背的软条 (总数) : 14 - 15; 臀棘: 0; 臀鳍软条: 19 - 22; 脊椎骨: 42. Diagnosis: Body slender, its depth 22-25% of standard length; pre-pelvic scutes not strongly keeled, beginning under or behind base of last pectoral finray, 8-10 pre-pelvic and 6-9 post-pelvic scutes, belly rounded; snout bluntly rounded; lower jaw not projecting, exactly meeting tip of upper jaw when mouth closed, deepest at mid-point of jaw, with small saw-like teeth on each side; pre-maxillae with small teeth pointing downward; maxilla very slender, its blade over 3 times as long as deep, upper edge ridged, lower edge without denticulations; posterior supra-maxilla minute, virtually without anterior shaft; lower gillrakers 14-17; silver stripe along flank, narrower anteriorly (Ref. 188, 28136). The presence of small horny denticles on snout and edges of mouth on the skin of the maxillary is typical for this species (Ref. 188, 93833). It closely resembles Potamothrissa obtusirostris, which lacks dermal denticles on the snout and has more post-pelvic scutes, 9-12 vs. 6-9; Potamothrissa acutirostris has a pointed snout and more gillrakers, 16-18 vs. 14-17 (Ref. 188, 28136). Other pellonulines lack saw-like teeth at the sides of the lower jaw (Ref. 188).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
前腹鳍鳞甲不有明显的龙骨, 开始在或下面最后胸鳍鳍条的在后基底,8 到 10+7 到 9. 吻圆的; 下颌不是突出, 当嘴巴闭合时完全碰到上颌的顶端, 深的在中央点, 有小的像见到一样的牙齿在两边; 前颚有小的分向朝下的齿; 颚骨非常细长的; 第二个上颚骨细小又事实上没有轴。
