About the species
Lethrinops sp. "Macrostoma" is an undescribed sand-dwelling cichlid recorded from the South East Arm of Lake Malawi. Its trade name combines the Greek roots macro- ("large") and -stoma ("mouth"), pointing to an unusually large oral gape relative to other Lethrinops sharing its habitat. The name is purely descriptive rather than a nod to any specific described relative, and it should not be confused with Tyrannochromis macrostoma (Regan, 1922), a large predatory cichlid in an entirely different Lake Malawi genus that independently carries the same descriptive epithet. No authority, publication year, FishBase number, or Red List status exists for this form.
