背棘 (總數) : 0; 背的軟條 (總數) : 67 - 84; 臀鰭軟條: 55 - 69. Diagnosis: head length 22.3-27.1% SL (Ref. 101841). Head pointed in dorsal outline; snout slightly rounded; eyes dorsally located (Ref. 248). Interorbital distance 41.4-48.6% HL (Ref. 81644, 101841). Tooth plates relatively small (Ref. 248), width of premaxillary tooth plate 24.3-30.7% HL, and of vomerine tooth plate 20.9-27.5% HL (Ref. 81644, 101841). Maxillary barbel length 105.1-195.3% HL; outer mandibular barbel length 95.0-134.5% HL (Ref. 81644, 101841). Nasal barbel length 72.1-130.2% HL; inner mandibular barbel length 72.4-108.9% HL (Ref. 81644). Frontal fontanelle long and narrow (`knife-shaped'); occipital fontanelle oval- shaped and relatively large; supraorbital and the `dermosphenotic' joined by a common suture in specimens over 70 mm SL; dorsal and anal fin nearly reaching caudal fin, but not confluent; gill rakers long and slender, increasing with age (Ref. 248). Openings of secondary canals along lateral line visible as irregularly placed white spots on the body (Ref. 248, 81644). Pectoral spine strongly serrated on outside and inside (Ref. 81644, 101841). Surface of cleithrum exposed through skin is intermediate; inner angle formed by both paired bones sharp; cleithrum length 13.0-18.6% HL; dorsal fin length 65.1-73.8% SL; distance from dorsal to caudal fin 0.9-2.7% SL (Ref. 101841). 10-23 gill rakers on first arch (Ref. 81644).
Colouration: preserved specimens with uniform colouration; dorsum, flanks and dorsal parts of paired fins dark brown, ventrum and ventral parts of paired fins pale brown to grey (Ref. 248, 81644, 101841). Some specimens may show irregular pattern of small white spots on body (Ref. 101841).
頭部尖的在背部的輪廓中; 吻略圓的。 眼位於背面。 額骨囪門長而狹窄的;(刀狀的') 後頭骨囪門橢圓形而相當大的。 那眶上的與那皮蝶骨的' 被一個普遍縫合在超過 70 mm SL 的標本中連結了。 齒碟相當小的。 背鰭與臀鰭幾乎延伸到尾鰭, 但是不是匯合。 鰓耙長且細的, 隨著年齡增加。 第二感覺管的開口沿著側線看得見的當不規則地放白色的斑點在身體上了。
Facultative air-breathing (Ref. 126274); Inhabits rivers, lakes and swamps. Feeds on a variety of food like algae, plants, Hydracarina, larvae of Ephemeroptera, Chironomidae, Ceratopogonidae, remains of remains (Coleoptera) and fish remains (Cichlidae, Anabantidae) (Ref. 248). Maximum size reported in Lower Guinea is 317mm TL (Ref. 81644).
