Tribe Steatocranini

Steatocranus irvinei (2n = 42), previously assigned to the tribe Gobiocichlini , has been placed in the new tribe Steatocranini , although its generic status remains unclear ( Dunz and Schliewen, 2013). This rheophilic species is endemic to the Volta basin. Steatocranini are a sister group to all other haplotilapiine species (sensu Schliewen and Stiassny, 2003; Dunz and Schliewen, 2013), with the exception of the Het-

erochromini. Unlike the Tilapiine species karyotyped to date (reviewed and updated in Poletto et al., 2010 and the present work), its first acrocentric pair is only twice as large as the small acrocentrics and probably originates from a tandem fusion between two small elements. Its first chromosome pair in size is a large metacentric probably arising from a centric fusion. It is also characterized by the presence of four small metacentric pairs.
