Africa: widely distributed in the lower and middle Congo River basin (Ref. 28136, 54749), including Sangha River and Ubangui River (Ref. 188), but also in Lualaba River (Ref. 188) and Upper Lualaba River (Ref. 45434). Perhaps also in rivers of Angola (Ref. 188).

Maturity: Lm ? range ? - ? cm
Max length : 14.4 cm SL 雄魚/尚未辨別雌雄; (Ref. 54749)
背棘 (總數) : 0; 背的軟條 (總數) : 15 - 18; 臀棘: 0; 臀鰭軟條: 19 - 24. Diagnosis: Body slender or moderate, its depth about 22-29% of standard length; 10-14 pre-pelvic and 7-10 post-pelvic scutes, no pre-pectoral scutes, first scute beginning slightly before or behind base of last pectoral fin ray and identical as following scutes without ascending arms; lower jaw strongly projecting, with strong canine teeth at symphysis; pre-maxilla with one large backward-pointing canine tooth on each side, about halfway along normal pre-maxillary series, rarely 1-2 smaller ones beside or a little behind it; lower gill rakers 18-29, shorter than corresponding gill filaments and the anterior ones reduced to stumps in large adults; anal fin with 19-24 rays; silver stripe along flank (Ref. 188, 54749). It resembles Pellonula vorax, which lacks canine teeth in the upper jaw and has one or more pre-pectoral scutes (Ref. 188).
在最後的胸鰭鰭條後面的鱗甲開始; 下頜強烈突出, 在瘉合處有強的犬齒; 一個大的犬齒大約半路地沿著被彎曲而且向後地指出的正常的前顎的系列 (很少地一個比較小的在或旁邊稍微往後它) 。 下鰓耙短與前面的一些在大的成魚中縮小成殘枝了。 銀色的斑紋沿著側面。
Found in rivers and streams (Ref. 188), also lakes (Ref. 41580). A small predator, feeding on shrimps, mayfly nymphs and little fish (Ref. 41580, 54749).
出現於河川與溪流。
