The name Diapteron ( Greek synonym for "displaced fin" or "forward-shifted fin") denotes a sub-genus of fish from the order of the toothfish (Cyprinodontiformes) living in Africa .
Occurrence
The occurrence extends to Gabon and the north-eastern Republic of the Congo , in the catchment area of the Ivindo . It is assumed that the species of the subgenus Diapteron are relic forms . A differentiation from the other aphyosemions is possible due to the small size and above all due to the dorsal that is attached in front of or at the same level as the anal . The fish inhabit small, swampy remnants of streams in the rainforest .
Appearance
The animals of all four valid species reach a maximum total length of about three to four centimeters. The body is elongated and has an approximately round cross-section; the dorsal and anal areas start roughly in the middle of the body. The sexual dimorphism is very pronounced, the female animals have a gray-brown or brown basic color and have transparent or only inconspicuously colored fins. The males, however, feature intense red and blue colors, males of the species D. georgiae and D. fulgens have about orange ribbons in addition anal and caudal on.
species
- Diapteron abacinum (Huber, 1976)
- Diapteron cyanosticum (Lambert & Géry, 1968)
- Diapteron fulgens (Radda, 1975)
- Diapteron georgiae (Lambert & Géry, 1968)
- Diapteron seegersi (Huber, 1980)
For various reasons, it has not yet been finally clarified whether Diapteron seegersi is a valid species.
