Các tia vây lưng cứng (tổng cộng) : 18 - 19; Các vây lưng mềm (tổng cộng) : 7 - 9; Tia cứng vây hậu môn: 3; Tia mềm vây hậu môn: 7 - 8. Diagnosis: Female and subadult Melanochromis loriae are distinguished from their congeners, except those of M. melanopterus, M. lepidiadaptes, and M. kaskazini, by a white to cream coloured body vs. yellow to brown in other congeners, two black horizontal stripes on the flank, a black submarginal band in the dorsal fin, and black markings on the lower lobe of the caudal fin; Melanochromis loriae is distinguished from M. melanopterus and M. kaskazini by a shorter lower jaw, 31.9-35.2% of head length vs. 37.2-41.7% on M. melanopterus and 36.4-44.6% in M. kaskazini, and from M. lepidiadaptes by the higher number of tooth rows, 5-7 vs. 2-3 (Ref. 89864). Male Melanochromis loriae in breeding colouration are distinguished from their congeners, except M. melanopterus, M. simulans, and M. robustus, by a broad black band in the spinous part of the dorsal fin, absent in all congeners; it is distinguished from M. melanopterus and M. simulans by a shorter lower jaw, 31.9-35.2% of head length vs. 37.2-41.7% in M. melanopterus and 40% in M. simulans, and from M. robustus by a shallower caudal peduncle, 11.7-12.6% of standard length vs. 12.9-14.4% (Ref. 89864).
The preferred habitat is mostly rocky with little sand, and the majority of individuals occur at a depth ranging between 5 and 20 meters (Ref. 6307, 89864). It is an omnivore, feeding mainly from the Aufwuchs on rocks; in addition to algae also cichlid fry and catfish eggs are observed in the stomach contents (Ref. 89864).
