Hadrothemis versuta (Karsch, 1891)
Variable Jungleskimmer

Type locality: Cameroon, no locality data available.

Diagnosis

Male is similar to H. defecta by (a) labium pale with contrasting black central marking, sometimes all black; (b) labrum at least partly black; (c) wing bases broadly brown, tips not or comparatively faintly so; (d) no cell-doublings (rarely 1 or 2) in medial planate of Fw and Hw; (e) 1 Cux in Hw, rarely 2; (f) anterior lamina at most as high as hamule; (g) Abd broader and tapered towards end, S2 over 3 mm broad. However, differs by (1) sides of thorax usually black with contrasting yellow stripes, rather than uniformly dark; (2) subtriangle usually of 4 cells, but can vary from 3 to 5; (3) Hw triangle of 2 cells; (4) brown of Hw base usually includes triangle; (5) hook of hamule longer than lobe, opposing corner of which is angled; (6) Abd initially red but darkens and becomes pruinose with maturity.
