The holotype of Maylandia cyneusmarginata, an adult male (PSU 3056,
Penn State University) measuring 73.9 mm SL, from Nkhotakota, the only
locality from which the species is known.
(For comments on the spelling of the specific name, see
Note 7.) This form apparently has not
been known by an informal name.
According to the diagnosis
provided for this species (Stauffer et al., 1997: 201),
M. cyneusmarginata is distinguished from other members of
its genus by having a blue marginal band [in the dorsal fin] and
brown lappets (the rounded or pointed edge of the fin membrane between
the tips of each two consecutive spines).
Breeding males of M. cyneusmarginata "have a blue ground
coloration laterally with 5-6 gray vertical bars and a white belly.
Dorsal fin blue/gray with a blue marginal band and brown lappets..."
