A. namaquensis stat. nov. (FitzSimons, 1938)

Distribution. Known from scattered localities in the Succulent Karoo Biome in the Little Namaqualand region of the Northern Cape Province (Bauer 2014a) (Fig. 4).

Remarks. Haacke (1965), in describing A. africana tirasensis considered A. namaquensis as a subspecies of A. africana, and it has maintained this rank since (Mertens 1971; Branch 1981, 1988, 1998; Onderstall 1984; Bauer 2014a), although chiefly because this poorly known taxon has not been reviewed subsequently. Under modern species concepts, the differences between the supposed subspecies of A. africana— including precloacal pore counts, presence of internasal granules, gular scale counts, and color pattern (Haacke 1965) would generally be accepted as evidence of specific distinctness, especially in light of the large disjunctions between the forms and their likely low vagility (Mouton & Mostert 1985; Jacobsen 1997). On this basis we here recognize this taxon at the rank of full species.
