Diagnosis. Adults of A. bitis resemble those of A. dyscrita in their large body size and broad forewings (Fig. 89), but A. bitis can easily be distinguished from A. dyscrita by a combination of the following characters: A. bitis has dense white hairs over the whole thorax (Fig. 104) while in A. dyscrita the prescutum is covered in stiff black hairs (Fig. 102). Moreover, A. bitis has long antennae that reach the pterostigma (Fig. 89) while in A. dyscrita they do not (Fig. 129).

Size (mm). Male: body length 9.8 (8–11.7); forewing 23.6 (18.7–27.0); hind wing 55.7 (41.1–64.8); antenna 21.7 (17–25.5); Female: body length 11.2 (9.3–13.7); forewing 22.7 (19.2–26.3); hind wing 49.4 (42–55.6); antenna 15.2 (12.3–18.2). (N = 319).

Distribution and habitat. Afroptera bitis is endemic to the Northern Cape Province, South Africa, from localities mainly centred in the Richtersveld and Bushmanland Bioregions (Fig. 152). The Bioregions fall mainly within the Succulent and Nama Karoo Biomes. The habitats vary from arid mountainous desert with a succulent vegetation type and winter rains in the Richtersveld Bioregion to arid habitats dominated by shrubs and grass, characterized by late summer rains in Bushmanland (Mucina & Rutherford 2006).
