Hadrothemis vrijdaghi Schouteden, 1934
Golden-winged Jungleskimmer

Type locality: Coquilhatville [= Mbandaka], DRC

Diagnosis

Male is similar to H. camarensis by (a) frons at least partially dark metallic; (b) labrum all pale, sometimes dark brown or black; (c) labium all pale; (d) vertex without tubercles; (e) thorax and Abd dull brown to black, not rufous; (f) numerous cell-doublings in medial planate of Fw and often Hw; (g) Pt seldom over 4 mm long; (h) S2 under 4 mm broad. However, differs by (1) being restricted to the C Congo Basin; (2) mesepisterna largely blackish to brown, like sides of thorax; (3) wings all deep golden-yellow; (4) Fw triangle of 3 cells (rarely 2 or 4), subtriangle of 5-6 (occasionally varies 3-8).
