Maylandia pyrsonotos, photographed underwater at Nakantenga Island in the Maleri Islands group, Malawi. This is the species informally known under the name Pseudotropheus zebra "red dorsal."
Stauffer et al. (1997),
M. pyrsonotos is one of three species having a blue ground color,
black vertical bars, and a reddish dorsal fin (the others being
M. emmiltos and
M. sandaracinos.) M. pyrsonotos
is the only one in which the black vertical bars extend into the basal
portion of the dorsal fin. (Actually, Stauffer et al. discuss a fourth
species with blue ground color, black vertical bars, and orange dorsal
fin M. thapsinogen from Eccles
Reef but that species may
be recognized by having a yellow chin or gular area.)

Ribbink et al., 1983, who first
recognized that this was a distinct species;
