Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335). More on author: Trewavas.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Africa: Ndian (Ref. 81251), Mungo and Cross basins in Cameroon (Ref. 13094, 57223, 81251) and Nigeria (Ref. 31256). Reports from the Niger basin (map in Ref. 57223) questionable and unconfirmed (Ref. 13094, 81251). Report from Chad basin (Ref. 13331) erroneous (Ref. 81251).

Morphology | Morphometrics
Vertebrae: 30 - 32. Diagnosis: labial disk rounded and moderately developed (Ref. 57223, 81251), bearing very small barbels (Ref. 57223). Mandibular barbels small; no auxiliary mandibular barbels; papillae of upper lip with distinctive frond-like margins (Ref. 81251). Premaxillary teeth large, arranged in 3-4 rows; mandibular teeth numbering 8+8 to 10+10, usually arranged in 2 rows; eye small; caudal peduncle relatively deep; caudal fin weakly forked, with rounded lobes, lower longer than upper (Ref. 57223, 81251). Apparently no sexual dimorphism, but all individuals so far examined seemed to be immature (Ref. 57223). Top and sides of body with sharply contrasting dark vertical bands alternating with pale areas (Ref. 81251).
Coloration: live specimens: 3 very well defined black vertical bars; dorsal area from head to dorsal-fin origin, or to 1st vertical bar, yellow-orange to brown-orange, depending on individuals; light areas of body and of dorsal, adipose and caudal fins bright yellow or even lemon-coloured; pectorals, pelvics and anal fin pale yellow; faint dark cross-bars on central part of pectoral fins; anterior parts of adipose and anal fins marked with black dots; caudal fin with 4 yellow spots underlined with black; belly beige/cream or whitish (Ref. 57223, 81251).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
