Africa: Nile basin, LakesTurkana, Albert, Edward and Kioga (Ref. 3202, 82238), and Shabeelle River (Ref. 3202, 82238). Reported from Lake Edward (Ref. 3202, 82238), but Mochokidae are not present in the lake (Ref. 120232). Its presence in Chad basin (Ref. 367) is questionable and needs confirmation (Ref. 7362, 57223, 82238).

Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 1; Mjukstrålar i ryggfenan (totalt): 7; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 13. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; interorbital space over 50% of head width; post-orbital length at least 60% of snout length; maxillary barbels longer than head, unbranched, without tubercles and bordered by a short but distinct, dark basal membrane; outer mandibular barbels with rather numerous, simple ramifications, branches of inner mandibular barbels subdivided, thick and tuberculate; mandibular teeth rather short, numbering 36-48; denticulations of pectoral-fin spines strong on inner, and hardly visible on outer margin; dorsal-fin spine smooth anteriorly, except for some apical denticles; first branched ray of dorsal and pectoral fins prolonged into a filament; adipose fin high and long, distincly separated from rayed dorsal fin; humeral process deep, pointed and granulose, not keeled ventrally; body covered with very small black specks; caudal fin without spots or dots (Ref. 57223). Coloration: uniformly brownish, with numerous very small black spots, also on adipose fin, but none on other fins (Ref. 57223).

Biologi     Ordlista (t.ex. epibenthic)

Found in deep, open waters and shallow inshore areas of Lake Albert (Ref. 49805). Occurs in lakes and channels; feeds on algae, macrophytes, detritus, crustaceans, insects and mollusks; breeding takes place during flooding in June to early dry down in January (Ref. 28714). Oviparous (Ref. 205).
