March 21st, 2012 — 3:59pm

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.

Aphyosemion herzogi RADDA, 1975

March 21st, 2012 — 2:47pm

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.

Aphyosemion decorsei (PELLEGRIN, 1904)

March 21st, 2012 — 2:10pm

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.

Aphyosemion congicum (AHL, 1924)

March 21st, 2012 — 1:55pm

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.

Aphyosemion cognatum MEINKEN, 1951

March 21st, 2012 — 1:00pm

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.

Aphyosemion bualanum (AHL, 1924)

March 21st, 2012 — 11:46am

Described from ‘Buala, Cameroon’, which corresponds to modern-day Bouala in Central African Republic. It’s known distribution includes parts of northern Cameroon, western Central African Republic, southeastern Chad and possibly eastern Nigeria in the upper Benue and Mayo Kébbi river systems.

The specific name was mis-used to refer to various populations of the congener A. elberti prior to 1990, and we’ve been unable to confirm if the specimen pictured here is correctly identified or not. It is listed as ‘endangered’ by the IUCN.

Aphyosemion rectogoense RADDA & HUBER, 1977

March 21st, 2012 — 10:35am

Known only from the Batéké plateau region and surrounding area in southeastern Gabon where it’s been recorded from the Léconi-Djouya and upper Mpassa rivers, these forming a portion of the much larger Ogooué basin. Type locality is ‘6 km west of Léconi’, the latter presumably referring to the settlement of that name.
