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’.

Collections of wild fish are generally lab…

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 Assinie-Mafia in south-eastern Côte d’Ivoire (Ivory Coast), western Africa but currently accepted to be extensively distributed in coastal river drainages of central western Africa from the Saint John River, central Liberia to the Cross River drainage, in southeastern Nigeria and southwestern Cameroon. It also occurs in the Niger and its major tributary the Benue (Bénoué) and has thus been recorded from Benin, Burkina Faso, Cameroon, Côte d’Ivoire, Equatorial Guinea, Ghana, Guinea, Liberia, Mali, Niger, Nigeria and Togo.

The genus Barbus is in something of a confused state classification-wise. While there exist almost 340 putative species the vast majority of them do not appear to be closely-related to the genus Barbus sensu stricto.

Berrebi et al. (1996) proposed that only the European, Southwest Asian and North African representatives should be included in Barbus (around 20 species) and that ‘all species of Barbus sen…

This species is also known as ‘Gardner’s Killi’ and ‘blue lyretail’ and the commonly-available aquarium forms are perhaps among the best choices for those new to keeping killifishes being relatively hardy, colourful and easy to breed.

A number of ornamental strains have also been line-bred by aquarists including ‘gold’ and ‘albino’.

Distributed throughout coastal regions north and westwards from Gabon through Equatorial Guinea, Cameroon, Nigeria, Benin and Togo as far as Ghana although some consider it restricted to northwestern Gabon and Equatorial Guinea with the remaining populations representing various subspecies (see ‘Notes’).

Type locality is ‘Gaboon River’, which presumably refe…

Following Bonou and Teugels (1985), P. africana can be distinguished from congeners by the following combination of characters: colour pattern unique, comprising a series of 8-11 dark, chevron-shaped markings extending along the body posterior to the pectoral fins; 19-24 scales in the transverse series; lateral line complete with 73-83 pored scales; 45-48 dorsal-fin rays 45-48; 32-35 anal-fin rays.
