Known only from a relatively small area near the villages of Takwai I and II, Atebong Wire and Edjuingan in wester Cameroon, with records existing from the Bagwor and Mack river systems both of which are tributaries within the upper Cross River basin, western Cameroon.

Type locality is ‘West Cameroon, 5°34’N, 9°50’E’.

Endemic to the Ubangi (also spelled Oubangui) River drainage in southwestern Central African Republic with type locality given as ‘Small stream along Mbaiki-Mongoumba road, south of Bangui, 3°55’N, 18°10’E, Central African Republic’.

Following the key of Romand (1992) this species can be told apart from congeners by the following combination of characters: adult size > 40 mm SL; large, dark, transverse bars and some reddish-brown pigmentation on flanks; longitudinal bands more-or-less defined; longitudinal bands composed of small red spots; caudal-fin subquadrangular caudal fin; 11-13 anal-fin rays; 16-17 dorsal-fin rays; 7-8 anal-fin rays located anterior to dorsal-fin origin.

Native to northwestern Africa with a range extending southwards from Guinea-Bissau through coastal parts of Guinea and Sierra Leone as far as western Liberia, around the city of Monrovia.

Type locality was originally given as ‘Sierra Leone’ and ‘Upper Nile’ but this was later changed to ‘Freetown, 8°30’N, 13°15’W, Sierra Leon’, referring to the capital of Sierra Leone.

Type locality is close to a waterfall on the Ndian River in southwestern Cameroon, and appears restricted to the coastal plains either side of the border between Cameroon and Nigeria, including the Korup and Cross River National Parks.

This species is widely-distributed in lowland, coastal regions of Togo, Benin and Nigeria as far as the Cross River delta, and occurs at some inland localities along the lower Niger River. Populations in Cameroon, Equatorial Guinea and Gabon are now considered to represent other species.

Described from northern Gabon, close to ‘Zoumoukou’, which is seeen on modern maps as ‘Zomoko’, but has a much wider distribution extending into Equatorial Guinea (upper parts of some Benito River tributaries), and southern Cameroon (Ntem River), as well as the Ivindo and Okano drainages in Gabon, the latter pair both tributaries of the much larger Ogooué system.

Type locality is the settlement of Bessou, Lobaye prefecture, Central African Republic, which lies within the Ubangi (also spelled Oubangui) River basin. The Ubangi is a major tributary of the Congo River and this species appears restricted to its middle section and thus probably extends into northern Republic of Congo and Democratic Republic of Congo.

The type series was derived from a commercial shipment and this species’ natural range remains unconfirmed. It may be restricted to the area between the Kwango and Gamba rivers, the latter a tributary of the former, in western Democratic Republic of Congo. The Kwango is itself a tributary of the Kasai, an affluent of the Congo.

The type material was derived from a commercial shipment of fishes from Leopoldville, now Kinshasa, Democratic Republic of Congo, and presumed to have been collected in the vicinity. The precise extent of its distribution unknown but appears extensive in the middle and lower Congo regions, with specimen collected from Lac Fwa (Sankuru River drainage, a Congo River tributary), many hundreds of kilometres west of Kinshasa, identified as belonging to this species.
