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 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 elberti (AHL, 1924)

March 20th, 2012 — 11:09pm

This species’ currently accepted range stretches from eastern Nigeria (Mbam River) across central Cameroon (via the Sanaga River system of which the Mbam is a tributary) and across the border into Central African Republic (upper Mambéré basin).

It was described from ‘Jade Plateau, Cameroon’, this apparently corresponding to the Lebo River which lies in what is now the Central African Republic and presumably forms part of the Mambéré headwaters.

Chromidotilapia guntheri (SAUVAGE, 1822)

March 13th, 2012 — 1:26pm

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.

Barboides gracilis BRÜNING, 1929

March 13th, 2012 — 1:24pm

This species is still very rare in the hobby although it has built up something of a following among enthusiasts of planted 'nano' aquaria and you may see it on sale under the trade names of 'dwarf amber/ember barb'. Its small adult size evolved via a process known as miniaturisation characterised by sexually mature adults with a significantly reduced size of less than 20mm SL. Among bony fishes cyprinids are one of the few groups in which this phenomenon occurs repeated…
