The Chromidotilapiini are a tribe of the cichlids (Cichlidae) to which about ten genera with over 50 described and about 10 previously undescribed species are placed. Species of the Chromidotilapiini occur in West Africa in Niger and Benue and in the regions south of the Niger Arc, in Lower Guinea and in the northern Congo Basin . They are predominantly inhabitants of smaller rivers (fluvatil), only in Lake Mai-Ndombe and in Lake Tumbasee in the west of the Democratic Republic of the Congo and in the Cameroonian crater lake Barombi Koto there are also lake inhabitants among the Chromidotilapiini.

features

The independence of the tribe and the difference to other African cichlid tribe is only supported by molecular biological data. Diagnostic morphological features of the tribes could not be determined so far. The fish reach body lengths of 6 to 20 cm.

All Chromidotilapiini are cave or mouth brooders.

Systematics

The following cladogram shows the internal systematics of the Pseudocrenilabrinae (the African cichlids) and the position of the Chromidotilapiini as a sister group of the Haplotilapiini, the cichlids that live in the East African large lakes:

Pseudocrenilabrinae	Heterochromidini      Tylochromini      Hemichromini      Pelmatochromini      Haplotilapiini (cichlids of the East African Great Lakes)      Chromidotilapiini

The following cladogram shows the internal systematics of the Chromidotilapiini according to Schwarzer et al. (2015) and the paraphyly of the genus Chromidotilapia :

Chromidotilapiini	Pelvicachromis      Limbochromis      "Chromidotilapia" schoutedeni      Nanochromis      Congochromis      "Chromidotilapia" guntheri , "C." linkei & "C." regani      Benitochromis      Wallaceochromis      Thysochromis      Teleogramma      Divandu      Chromidotilapia sensu stricto      Parananochromis

Another genus of Chromidotilapiini is Enigmatochromis , which in the study by Schwarzer et al. has not been examined and is therefore not listed in the cladogram above. The genus Pterochromis was counted by Greenwood to the tribe Chromidotilapiini, but later by Lamboj to the tribe Pelmatochromini .
