- <p><b><i>Atherigona</i> (<i>Atherigona</i>) <i>fumivenosa</i> Deeming, 1972</b></p><p>Fig. 21</p><p><i>Atherigona fumivenosa</i> Deeming, 1972: 5, figs 7, 8; Dike 2003: 219 (distribution).</p><p><i>Material examined</i>: 1♂, Skeleton Coast Park, Kunene River Mouth, 17°15.97'S, 11°46.83'E, 10.ii.1999, E. Marais, Malaise trap sample (NMNW).</p><p><i>Remarks</i>: The specimen cited above differs from the type from Kenya, in that the trifoliate process in its apical part agrees perfectly with the figure of the type provided by Deeming (1972: 4, fig. 8), but the preapical extension is very much greater, as in that figured for <i>A</i>. (<i>s</i>. <i>str</i>.) <i>palustris</i> Deeming (<i>ibid</i>., fig. 2). It transpires that the type has the greater part of this broken-off (see Fig. 21 for full extent). It also lacks any fumosity on the wing membrane and the apical section of vein <i>R 4+5</i> is slightly curved forwards at its apical extremity (unlike <i>ibid</i>., fig. 7). The trifoliate process of the Namibian specimen is illustrated here as Fig. 21. There are on the plate-like part of the “trifoliate process” several groups of compact minute studs and a single projecting seta on either side. In addition, the fronto-orbital plate is not at all shiny and there are no longitudinal darker vittae on the scutum. Another peculiarity of this specimen is that all of the proboscis, with the exception of the basal segment, is very weakly developed.</p><p><i>Distribution</i>: (Afrotropical): Kenya and Namibia *.</p>
