Nemopterella exigua Tjeder, 1967: 493.
Etymology.Unknown, probably from the Latin word exigua(small) for its small size.
Typelocality: SOUTH AFRICA, Western Cape Province. Klaarstroom, 33°19’51’’S 22°32’05’’E. Typedepository. SAMC.
Diagnosis. Afroptera exiguais very similar in appearance to A. parvaand A. koranna sp. nov., due to its small size, rounded apex of the forewings ( Fig. 134), short antennae and black hairs on prescutum. It can however, be easily distinguished from the former species by the unstriped pronotum ( Fig. 101), short apical antennal segment ( Fig. 75) 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).
Type material examined. SOUTH AFRICA, Western Cape Province. Holotype ♂( Fig. 130), SAM–NEU– A001251 / Klaarstroom, Prince Albert District, [ 33°20’S 22°32’E], Mus Expd, Oct 1952(white printed label)/ Holotypus Nemopterella exiguaTjeder 1966(red handwritten label). ( SAMC). Other material examined. SOUTH AFRICA, Western Cape Province. 1♂, NEUR12588, Middeldrif Farm, Laingsburg District, 33°03’13’’S 21°16’14’’E, 708m, at light, 18.x.2009, A.P.Marais; 1♀, NEUR12589, Wamaker- skraal Farm, Laingsburg Dist., 33°01’24’’S 21°36’43’’E, 550m, 11.x.2008, J.B.Ball, A.P.Marais( SANC).
Distribution and habitat. Afroptera exiguahas a limited distribution restricted to the Western Cape Province, South Africa( Fig. 155). 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 typewhere 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 mmper year ( Mucina & Rutherford 2006).
