Maturity: Lm ? range ? - ? cm

背棘 (总数) : 0; 背的软条 (总数) : 14 - 16; 臀棘: 0; 臀鳍软条: 15 - 17. Diagnosis: Small, fairly slender fishes, depth around 22-24% of standard length; belly rounded, smooth, no trace of scutes before or behind pelvic fins; pelvic scute itself present, however, the tips of its lateral arms bifurcated; jaws about equal, with fine teeth; no second supra-maxilla; lower gillrakers 10 to 12; pelvic fin insertion just behind dorsal fin origin (Ref. 188). Scales large, 20-22 in longitudinal series (Ref. 188, 93833). Congothrissa gossei occurs with other clupeid species, but the smoothly rounded belly, absence of spiny post-pelvic scutes and lack of a second supra-maxilla makes it unmistakable (Ref. 188).
前 而且在腹鳍之后的鳞甲缺乏.(腹鳍鳞甲存在的, 它的侧面手臂的顶端分叉) 颚大约相等, 藉由细齿; 没有第二个上颚骨; 鳃条骨 3 或 4. 鳞片大的。 与其他的 pellonulines 生存在一起，但是平滑圆形的腹面, 缺乏刺状的在腹鳍之后的鳞甲而且没有一个第二个上颚骨使它明显。
A riverine species apparently found in the main stream of the Congo River (Ref. 188). It feeds on small shrimps, mosquito larvae and chironomid larvae (Ref. 188).
