Atoconeura biordinata Karsch, 1899
Common Highlander

Type locality: Kitope, Tanzania

Diagnosis

Male is similar to locally co-occurring A. pseudeudoxia 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) Hw base clear; (e) Abd never pruinose; (f) S4-9 with basal yellow spots, which are lateral on S4-6 and ventral on S7-9; basal spot S3 crescent-shaped; (g) underside of S7-9 at most with some fine hairs; (h) cerci more sinuous and epiproct shorter; (i) epiproct narrow and slender, with only slightly notched apex. However, differs by (1) ranging from S Kenya to N Zambia and Zimbabwe; (2) relatively smaller size, Hw 28-34 mm; (3) frontal shield (partly) pale rather than dark, antefrons dark; (4) vertex usually glossy black rather than brown; (5) poststernum flatter, covered with loose long, fine hairs; (6) inner surface of hind femora smooth and bare, save some fine hairs.
