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).

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 15 - 18; Spine anali: 0; Raggi anali molli: 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).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
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).
