Etymology: Maylandia: In honour of Hans J. Mayland, German ictiologist (Ref. 45335); glaucos: The specific epithet, glaucos, is Greek for bluish gray, in reference to the blue-gray body and fin colouration; it is treated as a noun in apposition (Ref. 86409).
Eponymy: Hans-Joachim Mayland (1928–2004) was a German ichthyologist, aquarist, photographer and writer. [...] (Ref. 128868), visit book page.

背面の脊椎 (合計) : 17 - 19; 背鰭 (合計) : 8 - 10; 肛門の骨: 3; 臀鰭: 7 - 8. Diagnosis: A moderately-sloped head and bicuspid teeth in the outer row of the jaws place this species in Maylandia (Ref. 86409). The absence of a black submarginal band in the dorsal fin in conjunction with a yellow gular region and branchiostegal membranes, and the light-brown coloured females that have yellow fin margins distinguish M. glaucos from other members of Maylandia, except M. chrysomallos and M. benetos; there are generally fewer teeth in the outer row of the lower left jaw, range 14–19, of M. glaucos compared to M. chrysomallos, range 15–25, and more compared to M. benetos, range 9–13 (Ref. 86409). On the basis of colour pattern, females of M. glaucos cannot reliably be distinguished from those of most other members of the Aurora group, but they differ from those of M. xanthos by a shorter lower jaw, 28.8–32.8% of head length vs. 34.6–36.7%; and from those of M. aurora by 8–11 vertical bars below the dorsal fin vs. 6 in M. aurora (Ref. 86409).
