The Mid-North Station population

Placidochromis nigribarbis "Mid-North Station" is the Mid-North Station population of Placidochromis nigribarbis, a geographic colour form from Lake Malawi in Lake Malawi part of the lake. It is the same species as Placidochromis nigribarbis, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Placidochromis nigribarbis is a small, little-known haplochromine cichlid endemic to Lake Malawi, one of the many deep-water Placidochromis named in a single stroke by the Belgian ichthyologist Mark Hanssens in his 2004 monographic revision of the genus. The epithet nigribarbis is Latin for 'black-bearded' (niger, 'black' + barba, 'beard'), most plausibly referring to a dark marking on the chin or lower jaw region of this deep-water Placidochromis, though the exact feature intended by Hanssens's original diagnosis is not confirmed here. It is documented from a locality malawi.si records as 'Mid-North Station' — most likely a fisheries or research trawl-survey station in the middle-northern part of the lake rather than a shoreline place name, and like its many relatives in the same revision it is known chiefly from preserved, trawled specimens rather than from living, brightly coloured fish.
