Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. 45335);  macrochir: From the Greek "macros" = big and the Greek "cheir" = hand, or pectoral fin in fishes, referring to the large pectoral fin (Ref. 52307).

Issue
Status of and differences between O. macrochir and O. mweruensis are not clear; the latter is possibly restricted to Luapula/Lake Mweru/Congo basin and builds a star-shaped nest, in contrast to the more widespread O. macrochir which builds a volcano-shaped nest; origin (and identification) of introduced specimens is also unclear, but they mainly originate from Lake Mweru/Luapula (Ref. 88). See also Ref. 2, 33478, 55074.
