简单描述 型态特徵 | 形态测量图

背棘 (总数): 22 - 26; 背的软条 (总数): 66-92; 臀棘 1-2; 臀鳍软条: 63 - 92; 脊椎骨: 74 - 82. Can be distinguished from other African mastacembelid species by following combination of characters: small eyes, anterior border of first dorsal spine situated before, above, or just behind posterior edge of pectoral fin; generally the color pattern is uniform (Ref. 28147).
能被藉由跟随组合特徵与其他非洲 mastacembelid 种区分: 小的眼 , 被位于的第一背鳍棘的前缘在,之前在, 之上或在胸鳍的后缘正后方; 通常颜色图案是均匀的。 (参考文献 28147)

生物学特性     字汇 (例如 epibenthic)

Collected mostly from the rapids. For specimens of the Lower Congo River basin (mainstream), water temperature was recorded at a range of 24.7-29.0°C, air temperature at 23.3-30.0°C, D.O. 8.0 mg/l, and pH 7.0-7.5 (Ref. 28147).

大部份收集了从急流。 因为下面刚果河流域 (主流) 的标本, 水温在多种的 24.7-29.0 °C 被记录, 在 23.3-30.0个 °C , D.O.8.0 mg/l 与酸硷度 7.0-7.5 的空气温度.(参考文献 28147)
