Abstract: | Six- and seven-band morphs have been identified in a cichlid, Cyphotilapia frontosa, that is endemic to Lake Tanganyika. These color morphs have allopatric distributions; the six-band morph is widespread in
the northern half of the lake while the seven-band morph is restricted to Kigoma on the east coast of the lake. Because no
specimens of the seven-band morph have been available for taxonomic study except for the holotype of C. frontosa, the taxonomic status of these morphs has not been discussed. In a recent survey at the lake, 21 specimens of the seven-band
morph were collected. A comparison of these with existing collection specimens of the six-band morph showed significant differences
in morphometric and meristic characters; however, because all characters largely overlapped between these morphs, they are
regarded as conspecific. |
