''Chalinochromis'' is a small and disputed cichlid genus from the subfamily Pseudocrenilabrinae. These ray-finned fishes are endemic to Lake Tanganyika in the East African Rift. The scientific name refers to the bridle-like markings across the heads of members of this genus. They have specialized jaws enabling them to feed on sponges.〔 (2007): Phylogenetic relationships of the Lake Tanganyika cichlid tribe Lamprologini: The story from mitochondrial DNA. ''Mol. Phylogenet. Evol.'' 45(2): 629–642. (HTML abstract)〕 This genus has a puzzling relationship with the extremely similar species placed in ''Julidochromis''. In their mtDNA NADH dehydrogenase subunit 2 sequence, ''Chalinochromis'' are closer to ''J. dickfeldi'', ''J. ornatus'' and ''J. transcriptus'' – in particular the latter two – than to any other living fish, while ''J. marlieri'' and ''J. regani'' are closer to ''Telmatochromis''. ''Julidochromis'' thus might need to be split in two, with ''Chalinochromis'' included in one lineage. Alternatively, there has twice been successful intergeneric hybridization between particular lineages of ''Julidochromis'' males and ''Chalinochromis'' females (males generally do not pass on mtDNA to their offspring). Yet another possibility is that ''Julidochromis'' is monophyletic and includes ''Chalinochromis''; in this scenario males of the common ancestor of ''J. marlieri'' and ''J. regani'' would have hybridized with females of the common ancestor of ''Telmatochromis''.〔 ''Chalinochromis'' are popular aquarium fishes, and require similar care to ''Julidochromis''. Like most lamprologine species, ''Chalinochromis'' are secretive during spawning, often choosing a small cave or crevice to spawn inside. In the aquarium the species often spawns under flat pieces of slate. ==Species== The three formally described species in this genus are as follows: * ''Chalinochromis brichardi'' Poll, 1974 * ''Chalinochromis cyanophleps'' S. O. Kullander, Mi. Karlsson, Ma. Karlsson & Norén, 2014 〔Kullander, S.O., Karlsson, M., Karlsson, M. & Norén, M.
