Lake Malawi, recorded exclusively from Msaka in the South West Arm,
based on specimens collected in June 2005.
Sexual dimorphism:
Breeding males show a dark grey to black body including pelvic and anal
fins, contrasted by white on the upper surface of the head, the dorsolateral
region surrounding the dorsal fin, much of the dorsal fin, and the upper
leading edge of the caudal fin. Females and immature individuals cannot be
diagnosed externally.
Breeding:
Polygynandrous; maternal mouthbrooder.
Special notes:
Assigned to the slender-bodied D. limnothrissa group and morphologically
very similar to Diplotaxodon limnothrissa. Known from a single collection at
Msaka, and no detailed morphometric or population genetic comparisons have
been published. It has been suggested that the distinctive male phenotype
may represent a developmental stage of breeding dress of another member of
the limnothrissa complex. No full genome sequence data are currently
available, and the taxonomic status of this form remains unresolved.
