Etymology: Maylandia: In honour of Hans J. Mayland, German ictiologist (Ref. 45335); pambazuko: The name pambazuko, from Swahili, means dawn or sunrise to note the orange/red dorsal fin of males, alluding to the orange/red sky of daybreak (Ref. 93436).

Dorsale stekels (totaal): 16 - 18; Dorsale zachte stralen (totaal): 8-10; Anale stekels 3; Anale zachte stralen: 7 - 8. Diagnosis: The presence of bicuspid teeth in the anterior portion of the outer row on both the upper and lower jaws and a moderately-sloped ethmo-vomerine block with a swollen rostral tip place this species in Maylandia (Ref. 93436). The yellow/orange dorsal fin of males in combination with distinct black bars on a blue ground colour and the absence of a yellow chin distinguish this species from all other members of the genus except for M. emmiltos and M. pyrsonotos (Ref. 93436). The lateral bars of male M. pambazuko infiltrate the proximal portion of the dorsal fin and can form a solid band in males of the Lundo population, while the lateral bars of most males of M. emmiltos and M. pyrsonotos stop at the base of the dorsal fin; in some individuals of the latter species narrow bar extensions are visible in the dorsal fin but none have been encountered with black membranes in the soft-rayed part of the dorsal, which is another character of the colour pattern of M. pambazuko; also the anal fin of male M. pambazuko is darker and often black, while that of most male M. pyrsonotos and M. emmiltos is light blue (Ref. 93436). Female Maylandia pambazuko have a light brown to beige ground colour while those of M. emmiltos and M. pyrsonotos are dark brown to blue-brown; Maylandia pambazuko has more teeth in the outer row of the left lower jaw than M. emmiltos and M. pyrsonotos, being 13-23 vs. 8-12 and 4-10 respectively, and differs further from M. emmiltos by a larger distance between snout and pelvic-fin origin, being 35,3-44,2% of standard length vs. 22,8-32,8% (Ref. 93436).
