__NOTOC__ ''Telmatochromis'' is a small cichlid genus of the subfamily Pseudocrenilabrinae. These ray-finned fishes are endemic to Lake Tanganyika in East Africa. ==Systematics== Analysis of their mtDNA NADH dehydrogenase subunit 2 (ND2) sequence shows that hybridization must have played some role in the evolution of this genus.〔 (2007): Phylogenetic relationships of the Lake Tanganyika cichlid tribe Lamprologini: The story from mitochondrial DNA. ''Mol. Phylogenet. Evol.'' 45(2): 629–642. (HTML abstract)〕 For one thing, it might be that ''Telmatochromis'' is close to ''Julidochromis'', which they somewhat resemble. A possibility is hybridization between the ancestor of ''Telmatochromis'' and a lineage of ''Julidochromis'' which later gave rise to ''J. marlieri'' and the Convict Julie (''J. regani''). Similar ND2 DNA has been found in these and ''T. bifrenatus'', ''T. brichardi'' and ''T. temporalis''.〔 ''T. vittatus'' on the other hand has a ND2 DNA sequence resembling that of ''Lamprologus congoensis'' and ''L. teugelsi''. But ''T. vittatus'' does not at all appear very similar to these species, and in fact may well be closer to ''T. bifrenatus'' and ''T. brichardi'' than to ''T. temporalis''. That would mean that male ancestors of ''T. vittatus'' had successfully interbred with female ''Lamprologus'' after the lineage of the former had diverged from its relatives.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Telmatochromis」の詳細全文を読む スポンサード リンク
