A. africana (Boulenger, 1888)

Distribution. Erongo Region, west central Namibia (Mouton & Mostert 1985; Griffin 2003) (Fig. 4).

Remarks. Since the work of Haacke (1965) A. africana has been considered a polytypic species (e.g., Branch et al. 1988; Rösler 2000; Kluge 2001; Griffin 2003). We here consider A. africana as a monotypic central Namibian endemic (see below). All three of our genetic samples originate from the Erongo Region of central Namibia and are thus presumably referable to A. africana sensu stricto. However, the levels of divergence among these samples (up to 19.34%) are comparable to or greater than interspecific differences elsewhere in the genus (Fig. 1), suggesting that further study of this taxon is required.
