Africa: Sanaga and Kribi in Cameroon, Ntem in Cameroon and Gabon, Mbini/Woleu and Ogowe in Gabon (Ref. 81644). Widespread in the lower and middle Congo River basin (Ref. 78218). Also reported from the Wagenia Falls and Lualaba/upper Congo (Ref. 106245). Also in the Chiloango drainage (Ref. 78218), but latter unconfirmed in Ref. 81644.
非洲: 中央的下游而剛果河流域。 貿易在德國限制 (Anl。3 BArtSchV). 也記錄自 Ntem 河流域下游。 (參考文獻 27928)

背的软条 (总数) : 72 - 83; 臀鳍软条: 56 - 65; 脊椎骨: 59 - 63. Diagnosis: head length 24.5-28.4% SL (Ref. 81644, 101841). Head broad, long and flattened, rectangularly outlined in dorsal view (Ref. 248), its width 17.4-21.9% SL (Ref. 81644). Eyes lateral; postorbital bones in contact (Ref. 81644). Interorbital distance 42.6-51.8% HL (Ref. 81644, 101841). Tooth plates extremely large (Ref. 248), width of premaxillary tooth plate 32.4-40.0% HL, and of vomerine tooth plate 26.4-36.2% HL (Ref. 101841). Frontal fontanelle somewhat intermediate between `sole-shaped' and `knife-shaped'; occipital fontanelle oval-shaped (Ref. 248). Pectoral spine straight (Ref. 248), strongly serrate on anterior margin only (Ref. 81644). 14 or fewer gill rakers (Ref. 101841), which are short and widely separated (Ref. 248). Supra-branchial organ consists of well-developed arborescent structures but not completely filling the cavity (Ref. 248). Dorsal fin length 60.4-65.6% SL; distance from dorsal to caudal fin 1.6-3.7% SL (Ref. 101841). Flank neuromasts arranged in a regular pattern (Ref. 81644).
Colouration: both in life and in preservation colouration is marbled: large irregular black blotches on a pale brown base present on back, flanks, dorsal and anal fins, and on posterior/upper side of paired fins; ventrum and lower parts of paired fins beige, as are distal parts of unpaired fins; caudal fin bears a series of pale and dark bands (Ref. 248, 81644, 101841). Never an irregular pattern of small white spots on body (Ref. 101841).
Body shape (shape guide): elongated; Cross section: oval.
不规则的黑色斑块也位于之上偶鳍的上侧面。 头部宽的, 又长又平的; 矩形地背面的边缘了。 额骨囱门略微介于之间唯一-形状的 ' 与刀状的'; 后头骨囱门椭圆形的。 齿板非常大。 胸棘直线。 鳃耙短的而且分得很开。 在上方-鳃的器官由发展良好的组成树枝状的结构但是不完全地填充洞。

Facultative air-breathing (Ref. 126274); Restricted to equatorial forest and galley forest rivers (Ref. 248). Inhabits smaller rivers, ditches and inundation zones (Ref. 78218). Feeds on fish (Ref. 248, 78218).
