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: Roberts.
Environment / Climate / Range
Freshwater; benthopelagic. Tropical, preferred ?
Africa: known only from the type locality in the Menchum River (Niger basin at Bamenda heights), Cameroon (Ref. 13094, 57223). Reports from the Cross (Ref. 13331) or from Nigeria (Ref. 31256) questionable and unconfirmed.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.5 cm SL male/unsexed; (Ref. 57223)
Morphology | Morphometrics
Vertebrae: 31. Diagnosis: labial disk longer than broad, very large and rounded; mandibular barbels very small; premaxillary teeth usually in 2 rows, numbering 8+8 to 10+10 (in smallest specimens 6+6 to 7+7); adipose fin small, beginning slightly ahead of anal-fin origin; caudal peduncle elongate; caudal fin 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).
Coloration: live specimens: uniformly dark, nearly black, except on 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).

Estimates of some properties 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), 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. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
