Atoconeura luxata Dijkstra, 2006
Western Highlander

Type locality: Meme, Atop, Cameroon

Diagnosis

Male is similar to A. pseudeudoxia and A. biordinata by (a) labrum all black, at most narrowly pale at base; (b) antero-lateral borders of postclypeus seldom darkened; (c) mesepisternum without transverse pale streak bordering antealar sinus; (d) Abd never pruinose; (e) underside of S7-9 at most with some fine hairs; (f) epiproct narrow and slender, with only slightly notched apex. However, differs by (1) Hw amber rather than clear at base of subcostal and cubital spaces; (2) basal spot S3 oval to triangular rather than crescent-shaped; (3) S4-9 all black except for large dorsal spot on S7; (4) cerci rather straight, rather than sinuous, and epiproct relatively long, rather than short.
