Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 13 - 18; Rayons mous dorsaux (Total) : 8 - 10; Épines anales: 3; Rayons mous anaux: 6 - 9. Diagnosis: The moderately sloped head, swollen rostral tip of the neurocranium, isognathous jaws, and the presence of bicuspid teeth in the outer rows of the jaws place this species in Maylandia (Ref. 27596). The red dorsal fin in combination with black bars on a blue ground colour distinguish this species from all other members of the genus except for Maylandia emmiltos, which also has a red dorsal fin; Maylandia pyrsonotos differs from all the other red top BB forms in that the vertical black lateral bars infiltrate the proximal portion of the dorsal fin (Ref. 27596).
Body shape (shape guide): fusiform / normal.
