Etymology. The generic name is derived from the words Africa for the continent of Africa and part of the name Neuroptera   since the genus is endemic to Africa.

The generic name Afroptera   is feminine, despite the species name ( munroi   ) being masculine, as it was named after Hugh Kenneth Munro ( Tjeder 1967).

Type species ( Fig. 111 View FIGURES 111–114 ). Nemopterella munroi Tjeder, 1967   , designated here.

Diagnosis. Small to medium-sized species distinguished by: (1) Forewings hyaline without spots or shading between Cx, shading over proximal Cx towards wing base ( Fig. 38b View FIGURES 34–38 ); (2) Subcostal and radial areas never shaded ( Fig. 38b View FIGURES 34–38 ); (3) Pterostigma distinct comprising a single costal cell with yellowish brown or dark brown colour ( Fig. 38a View FIGURES 34–38 ), adjacent costal cells before and after pterostigma never tinged ( Fig. 38a View FIGURES 34–38 ); (4) Number of costal cells less than 30; (5) Hind wings with whitish area bearing white setae ( Fig. 41 View FIGURES 39–41 ); (6) Apical segment of antennae partly or mainly membranous ( Fig. 39 View FIGURES 39–41 ); (7) Fifth abdominal segment with pair of pleuritocavae ( Fig. 34 View FIGURES 34–38 ); (8) Anal area never tinged ( Fig. 38 b View FIGURES 34–38 ).

Description. Size (mm). Male: body length 6.1–12.8; forewing 15.9–27.8; hindwing 31.7–64.8; antenna 11– 27.4; Female: body length 8.5–14.1; forewing 17–26.3; hindwing 35.2–60.0; antenna 9.4–18.7.

Head. Small to medium-sized, without pubescence, with long rostrum, broad vertex and well defined epicranial and postfrontal sutures ( Fig. 40 View FIGURES 39–41 ). Vertex much broader in females than males. In some species, vertex may have two yellow rounded spots near eye margins. Frons above antennae slightly elevated without transverse yellow spots as manifest in Nemia   , Nemopterella   and Siccanda   . Eyes protruding, either large where their diameter equals length of genae or small less than length of genae and always widely separated. In males, antennae may be short not reaching pterostigma or long reaching beyond pterostigma or same length as forewings, covered with short setae arranged in circles over antennal surface. Apical segment of antennae partly or mainly membranous with narrow sclerotised, pigmented setaceous area at base of segment and along dorsal surface of membranous area ( Fig. 39 View FIGURES 39–41 ). In females, antennae short not reaching pterostigma with apical segment typically ending in short, acute membranous portion.

Thorax. As in Nemopterella   but mid and lateral stripes indistinct or with unstriped thorax in some species. Thorax in males with long hairs while in females hairs are short and sparse. Legs as in Nemopterella   .

Forewings. As in Nemopterella   but proximal Cx in most species distinctly shaded brown or dark brown, with costal cells never shaded. Subcostal, radial and anal areas never tinged. Number of Cx less than 30. Pterostigma distinct comprising a single costal cell with brown or dark brown colour, adjacent costal cells before and after pterostigma usually not tinged except in some species females adjacent cells partly tinged. Hind wings with black setation from wing base to dark area with white setae in apical white portion.

Abdomen. As in Nemopterella   but longitudinal midstripe only present in a few species, dorsum uniformly brown in most, dark brown or blackish with yellowish, reddish or reddish yellow hind margins to tergites ( Fig. 34 View FIGURES 34–38 ). Lateral abdominal stripes ill-defined in most cases or appearing as brown or greyish brown shading along lateral margins of tergite. Male and female genitalia as in Nemopterella   .
