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.

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.
