Description of three new species of the genus Chromaphyosemion Radda, 1971 (Cyprinodontiformes: Nothobranchiidae) from the coastal plains of Cameroon with a preliminary review of the Chromaphyosemion splendopleure complex.

This dataset contains the digitized treatments in Plazi based on the original journal article Rainer Sonnenberg (2007): Description of three new species of the genus Chromaphyosemion Radda, 1971 (Cyprinodontiformes: Nothobranchiidae) from the coastal plains of Cameroon with a preliminary review of the Chromaphyosemion splendopleure complex. Zootaxa 1591: 1-38, URL: http://www.zoobank.org/urn:lsid:zoobank.org:pub:6D790764-9926-4979-BBA2-365F8465682DAbstractThree new species of the genus Chromaphyosemion Radda, 1971 are described from the coastal plains of Cameroon. They are distinguished from the phylogenetically and geographically close congeneric species through diagnostic characters of male color patterns. Some remarks on recently described species are made and a phylogenetic hypothesis of all currently known described species and all but two undescribed forms of the genus Chromaphyosemion based on mitochondrial DNA sequences is given. The molecular data support the monophyly of this genus as previously stated on the basis of morphological data and allow a review of the Chromaphyosemion splendopleure complex, a taxonomically confusing group. All newly described species are endemic to Cameroon, contributing to the high diversity and endemicity of the nothobranchiids in this country.ResumeTrois nouvelles especes du genre Chromaphyosemion Radda, 1971 sont decrites des plaines cotieres du Cameroun. Elles se distinguent des proches especes phylogenetiques et geographiques du genre par les motifs de couleurs diagnostics du male. Quelques remarques sont faites au sujet d’ especes recemment decrites. Une etude phylogenetique du genre Chromaphyosemion integrant toutes les especes connues ainsi que toutes les formes non decrites - a l’exception de deux - et basee sur l’ADN mitochondrial est proposee. Les donnees moleculaires, en accord avec des resultats prealablement publies sur la base de donnees morphologiques, supportent la monophylie du genre, et permettent une revue du complexe C. splendopleure, un groupe a la taxonomie mal etablie. Toutes les nouvelles especes decrites sont endemiques du Cameroun, et attestent de la haute diversite et endemicite des nothobranchiides de ce pays.
