Here is a note on classification of Guinea fowl I found:
Classification. Belshaw (1985) has classified guinea fowl as order Galliformes, family Numididae, but Howard and Moore (1984) placed them in family Phasianidae and subfamily Numidinae. There are four genera (Agelastes, Guttera, Numida, Acryllium) comprising seven species. Genus Numida consists of a single polytypic species meleagris and 22 subspecies. Crowe (1985) has used a simpler classification of Numida meleagris involving nine well marked subspecies which fall into thress groupings:
West African - N. m. galeata and sabyi
East African - N. m. meleagris and somaliensis
Central-South African - N. m. reichenowi, mitrata, marungensis, papillosa, and Coronata.
So it looks like the sabyi are W. African, the somaliensis E. African and the mitrata, reichenowi are Central-S. Africa.
Than leaves the damarensis to figure out.
