The primate genus Namaia was erected by Pickford et al., 2008, on the basis of a maxilla containing two molars found at the middle Eocene locality of Black Crow, Namibia. The name Namaia is however preoccupied by an ostracod genus, Namaia Green, 1963, found in the Mississippian Banff Formation at Bow River Valley, Alberta, Canada, hence the name of the genus (Nama means bow in the Indian Language). The type species is Namaia reticulata Green 1963. We rebaptise the primate from Black Crow Notnamaia, not only to underscore that it is not the same as Namaia, but also because it was found in the southern part of Africa (Greek notos - south). The type species is Notnamaia bogenfelsi (Pickford et al., 2008). Coincidentally, one of the meanings of the German word bogen is Bow).
