Melanochromis perileucos (formerly known as
Melanochromis "black-white johannii"), photographed underwater
at Likoma Island, Malawi. "M. perileucos may be distinguished
from other members of this genus, except M. elastodema, by
its faded, often interrupted, horizontal stripes in males. It may be
distinguished from M. elastodema
by its pale blue caudal peduncle [sic] compared with the
dark blue or almost black caudal peduncle
of M. elastodema. Melanochromis perileucos is the only
Melanochromis in which females may be white"
(Bowers & Stauffer, 1997: 58).
From the above diagnosis, the fish in the above photo
would seem to be closer to M. elastodema. Bowers & Stauffer,
however, identify their M. perileucos with the
M. "black-white johannii" of Ribbink et al. (1983), and this
photo (from Plate 9j of
Ribbink et al., 1983; reproduced by permission of the
Zoological Society of Southern Africa) is exactly that.
