توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 17 - 18; شعاع نرم باله پشتي (کل) : 9 - 10; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 7 - 8. Diagnosis: A moderately-sloped head and bicuspid teeth in the outer row of the jaws place this species in Maylandia (Ref. 86409). Both males and females are light blue, fading to white ventrally, distinguishing them from all other members of Maylandia, except M. callainos; male M. nkhunguensis are distinguished from those of the similarly coloured M. chrysomallos from the Gome population, M. estherae, and M. callainos, the latter two species of the sediment-free rocky habitat, by the yellow base of the pectoral fin, vs. no yellow pigment in males of the other three species; female M. nkhunguensis are light blue, lighter than those of the only other known species with all-blue females, M. callainos, which are a darker cobalt-blue; female M. estherae are either brown or orange/red); Maylandia nkhunguensis is further distinguished from M. callainos by a shorter lower jaw, 29.4-34.1% of head length vs. 34.9-43.3% (Ref. 86409).
