Synonymy
Nemopterella segregata Tjeder, 1967: 472.
Etymology. Unknown.
Type locality. Namibia. Kalkfontein, 28°01’S 18°45’ E.
Type depository. SAMC.
Diagnosis. Afroptera segregata is similar to A. munroi, being of similar size, shape of the forewings and abdominal colour. It can be separated from A. munroi by being more yellowish in colour (Figs 96, 123), with much longer body pubescence.
Size (mm). Male: body length 10 (8.2–11.1); forewing 23.5 (20.9–26.3); hind wing 56.0 (47.5–63.4); antenna 22.4 (18.5–27.4). Female: body length 10 (7–11.5); forewing 21.8 (18.4–24.4); hind wing 47.0 (39–52.4); antenna 13.8 (12.6–15.9). (N = 31).

Distribution and habitat. Afroptera segregata is known from South Africa and Namibia (Fig. 151). In South Africa, the known range of distribution is from the Richtersveld Bioregion in the Succulent Karoo Biome (Mucina & Rutherford 2006). The species seems to be associated with two different vegetation types: the Central Richtersveld Mountain Shrubland where the area is montane with succulent shrubs and herbs, and characterised by mild winter rainfall with an average of 60–200 mm per year. The species is also associated with the Goariep Mountain Succulent Shrubland where the habitat comprises the Goariep Mountain (Ploegberg), vegetated mostly by dense succulent shrubs and Aloe, and other types of trees. The area receives winter rains with MAP 70 mm. In Namibia, the distribution is in the Kalahari xeric Savanna Ecoregion where the habitat is an open Savanna, known for its extreme aridity and poor nutrient sandy soils; vegetated mostly by grasses, Acacia and Boscia trees. The area receives summer rains with an average of 150–500 mm per year (Lovegrove 1993; Dennis et al. 1997). Another population was found confined to the extension of the Succulent Karoo Biome in southern Namibia, which falls within the Namaqualand-Namib Domain in southwestern Namibia (Jürgens 1991). The area is characterised by winter rains and succulent vegetation.
