Distribution

Range Description

This species is known from Guinea to the Democratic Republic of Congo.

Central Africa: Chiloglanis batesii is found throughout the Congo basins (in the Lower and This species is known from upper Congo River basins, and in the Dja and the Kasai River systems, Central Congo River basin), and almost every river basin in Cameroon except the Ndian and Nyong Rivers. This species is probably heterospecific and represents a species complex. Records of C.batesii in the Lower Congo need confirmation.

Western Africa: In Western Africa, this species is found in the basins of the Niger, Chad (Central African Republic), and Cross (Nigeria). It has also been recorded in Guinea and Mali.

Diagnostic Description

Diagnosis: labial disk rather large; mandibular barbels reduced; mandibular teeth numbering at most 6+6, often 5+5, and occasionally 4+4; adipose fin rounded posteriorly, beginning slightly ahead of anal-fin origin; 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).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).
