Etymology: Maylandia: In honour of Hans J. Mayland, German ictiologist (Ref. 45335); xanthos: The specific epithet, xanthos, is Greek for yellow, in reference to the yellow belly and dorsal fin of breeding males; it is treated as a noun in apposition (Ref. 86409).

Các tia vây lưng cứng (tổng cộng) : 17 - 18; Các vây lưng mềm (tổng cộng) : 8 - 10; Tia cứng vây hậu môn: 3; Tia mềm vây hậu môn: 8 - 9. Diagnosis: A moderately-sloped head and bicuspid teeth in the outer row of the jaws place this species in Maylandia (Ref. 86409). The brown and blue/gray alternating lateral bars in conjunction with the yellow dorsal and dark anal fin of breeding males distinguish M. xanthos from males of all other members of Maylandia (Ref. 86409). Female M. xanthos are yellow/brown, usually more yellow than females of any other member of the Aurora group, but not all female M. xanthos can be distinguished according to the colour pattern; Maylandia xanthos is further distinguished from M. aurora males from the Mbweca and Tumbi Point populations that are similar but lack dark pigment in the anal fin, and from the neighboring M. glaucos by the lower jaw length, which is longer in M. xanthos, 34.6–36.7% of head length, than in M. aurora, 28.4–33.5% of head length, and in M. glaucos, 28.8–32.8% of head length (Ref. 86409).
