Scientists from Germany have named a new species of killifish discovered in West Africa.

Rainer Sonnenberg, Thomas Blum and Bernhard Misof of Zoologisches Forschungsmuseum Alexander Koenig in Bonn named the new killifish Episemion krystallinoron.

Episemion krystallinoron was described from the Monts de Cristal in northwestern Gabon and the nearby border of southeastern Equatorial Guinea.

The Episemion genus was previously monotypic, holding a single species - Episemion callipteron - which was described from the same region by Radda and Purzl in 1987.

The authors wrote in this week's issue of the journal Zootaxa that E. krystallinoron is clearly distinguished from callipteron by the differing male colouration.

Mitochondrial DNA evidence also supports the differentiation of the two species.

For more information on the new species see the paper: Sonnenberg R, Blum T and BY Misof (2006) - Description of a new Episemion species (Cyprinodontiformes: Notobranchiidae) from northern Gabon and southeastern Equatorial Guinea. Zootaxa 1361: 1-20 (2006).
