Nemopterella exigua Tjeder, 1967: 493 .

Etymology. Unknown, probably from the Latin word exigua (small) for its small size.

Type locality: SOUTH AFRICA, Western Cape Province. Klaarstroom , 33°19’51’’S 22°32’05’’E GoogleMaps .

Type depository. SAMC .

Diagnosis. Afroptera exigua is very similar in appearance to A. parva and A. koranna sp. nov., due to its small size, rounded apex of the forewings ( Fig. 134 View FIGURES 133–140 ), short antennae and black hairs on prescutum. It can however, be easily distinguished from the former species by the unstriped pronotum ( Fig. 101 View FIGURES 96–101 ), short apical antennal segment ( Fig. 75 View FIGURES 67–78 ) and darkened tips of femurs, and from the latter by having a different shape to the apical antennal segment and by the white pubescence on the mesoscutum and mesoscutellum instead of the black hairs that are present in A. koranna sp. nov.

Size (mm). Male: body length 7.7 (7–8.3); forewing 20 (17.5–22.5); hind wing 39.8 (35–44.6); antenna 13.5 (11–15.9). (N = 2).

Distribution and habitat. Afroptera exigua has a limited distribution restricted to the Western Cape Province, South Africa ( Fig. 155 View FIGURES 155–156 ). The collection localities fall within the Rainshadow Valley and Lower Karoo Bioregions in the Succulent and Nama Karoo Biomes respectively ( Mucina & Rutherford 2006). The habitat in the former bioregion is mostly flat to undulating land with Heuweltjies (small hills) formations and series of hills, dominated mostly by succulent shrubs, herbs and low shrubs. The area is characterised by low MAP (165 mm) because of the rainshadow of the Swartberg Mountains. While in the latter bioregion the species seems to be associated with dry habitats of undulating lands of mud and sandstone soils, mostly dominated by a Gamka Karoo vegetation type where the main components are dwarf spiny shrubs, Karoo shrubs and sparse low trees. The area receives autumn and summer rains with an average of 100–250 mm per year ( Mucina & Rutherford 2006).
