Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335).
Eponymy: George Latimer Bates (1863–1940) was an American farmer and amateur ornithologist. [...] (Ref. 128868), visit book page.

Entorno: milieu / zona climática / rango de profundidad / gama de distribución
Ecología
; agua dulce; salobre bentopelágico. Tropical; 5°N - 10°S
Africa: Niger basin (Ref. 57223, 81251), Oshun, Osse, Cross (Ref. 57223), headwaters of the Chad basin (Ref. 57223, 81251), and almost every river basin in Cameroon except the Ndian and Nyong; absent west of the Niger (Ref. 81251). Probably absent from the Congo basin where C. micropogon is found (see Ref. 87986).
Tamaño / Peso / Edad
Madurez: Lm ?  range ? - ? cm
Max length : 4.0 cm SL macho / no sexado; (Ref. 57223)
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 5 - 6; Espinas anales: 0; Vértebra: 30 - 33. Diagnosis: labial disk/sucker rather large (Ref. 57223, 81251), round or longer than broad rather than transversely oval (Ref. 81251). Mandibular barbels reduced; mandibular teeth numbering at most 6+6, often 5+5, and occasionally 4+4 (Ref. 57223, 81251). Adipose fin high (Ref. 81251), rounded posteriorly, beginning slightly ahead of anal-fin origin (Ref. 57223, 81251). Caudal fin deeply forked; eyes rather large; very pronounced sexual dimorphism: males (even in premature stages) with enlarged caudal fin, in particular the upper lobe which also becomes more pointed or even filamentous; males also have a large and rounded humeral process (Ref. 57223, 81251).
Coloration: live specimens: diffuse dark vertical bars (that may even form a marbled pattern) delimiting better defined paler (yellowish or olivaceous) areas; dark vertical bars also present at bases of pectoral and caudal fin bases, but caudal-fin lobes pale yellow; finally, anal fin marked with dark spots, but these are less distinct than those in C. disneyi collected at the same locality (Ref. 57223, 81251).
Body shape (shape guide): fusiform / normal.
Oviparous (Ref. 205). Maximum total length 47 mm (Ref. 3202).
