Abstract
Enigmatochromis lucanusi, a new cichlid genus and species, is described from Guinea (West Africa). It is a member of the chromidotilapiine cichlid clade, and differs from other genera within the group in a combination of morphological characters and coloration patterns; e.g., twelve circumpeduncular scales; three tubular infraorbital bones in addition to the lachrymal bone; upper lateral-line separated from the dorsal-fin base; first ray of pelvic fin in adult females of equal length or longer than second ray; sexual dimorphism well developed; small juveniles with 3–4 rows of irregular dark dots on body; and breeding coloration of females.References
