Africa: Menchum River (Benue system, Niger basin)(Ref. 13094, 57223, 81251) and upper Cross River (Ref. 13331, 81251) in Cameroon. Report from Nigeria (Ref. 31256) questionable.
Tamaño / Peso / Age
Madurez: Lm ? range ? - ? cm
Max length : 3.5 cm SL macho / no sexado; (Ref. 57223)
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 6; Espinas anales: 0; Vértebra: 31. Diagnosis: labial disk longer than broad, very large and rounded; mandibular barbels very small (Ref. 57223, 81251). No auxiliary mandibular barbels; premaxillary teeth large in 7-8 rows (Ref. 81251). Mandibular teeth usually in 2 rows, numbering 8+8 to 10+10 (in smallest specimens 6+6 to 7+7); adipose fin small/short, beginning slightly ahead of anal-fin origin; caudal peduncle slender, elongate; caudal fin (moderately) forked, lobes more or less equal in size; eyes very small; sexual dimorphism does not seem to exist, although mature individuals have never been examined (Ref. 57223, 81251).
Coloration: live specimens: uniformly dark, nearly black, except on abdomen/belly which is light; alternation of dark and pale areas typical of Chiloglanis species has not been observed in fresh specimens of this species, but becomes slightly apparent after preservation (Ref. 57223, 81251).
Body shape (shape guide): elongated.
