About the species

Nyassachromis sp. "Eucinostomus Yellow" is an undescribed open-water haplochromine cichlid from Lake Malawi's South East Arm, named for a yellow breeding-male coloration. The first element of its trade name has no confirmed derivation on record in the sources used here — it does not correspond to any Nyassachromis species this author can confirm as validly described, so it is treated as a field label rather than a resemblance claim. It has no formal description, no describing author, and no FishBase entry.
