Etymology: Maylandia: In honour of Hans J. Mayland, German ictiologist (Ref. 45335); koningsi: Named after Adrianus Konings for his comprehensive knowledge and for teaching the author most of what he knows about the fishes of Lake Malawi (Ref. 127491).
Eponymy: Hans-Joachim Mayland (1928–2004) was a German ichthyologist, aquarist, photographer and writer. [...] (Ref. 128868), visit book page.

Spine dorsali (totale) : 17 - 18; Raggi dorsali molli (totale) : 7 - 9; Spine anali: 2 - 3; Raggi anali molli: 7 - 8. Diagnosis: The moderately-sloped vomer, 43.1°, with a swollen rostral tip, bicuspid teeth in the anterior portion of the outer row of both upper and lower jaws, the lower jaw at a 45° angle to a line from the tip of the snout to the hypural plate, a lower jaw that is slightly longer than the upper, and its feeding at a 90° angle to the substrate place this species in Maylandia (Ref. 127491). The lack of conspicuous vertical bars on the flank and the dark submarginal band in the dorsal fin of male Maylandia koningsi distinguish it from all other species of Maylandia, except M. usisyae; males of M. usisyae have a gold-coloured flank while this is blue in male M. koningsi (Ref. 127491). Females of M. koningsi are entirely brownish yellow and thus distinguished from those of most other species of Maylandia, except for females of M. flavifemina and M. phaeos; the snout of the latter species is relatively longer than that of M. koningsi, 37.9-44.7% of head length vs. 26.6-33.1%, but females of M. flavifemina cannot reliably distinguished from those of M. koningsi apart from the fact that they have a larger size, maximum 79 mm standard length vs. 49 mm standard length for M. koningsi (Ref. 127491).
This species is a deep-water form and is usually found at depths greater than 15 m (Ref. 127491).
