Pseudagrion (B) commoniae (Förster, 1902)
Black Sprite

Type locality: Ethiopia, no locality data available.

Diagnosis

Species not particularly close to any other Pseudagrion species by similar to most by (a) often in open; widespread; (b) S8-9 both usually distinctly marked with black apically, sometimes pruinose; (c) cerci without flange, at most inner border of lower branch angled; (d) cerci at most with small basal tooth; (e) paraprocts often with dorsal knob. However, differs by (1) face, dorsum of head and dorsum of thorax entirely black, postocular spots and antehumeral stripes absent; (2) tibiae dark, like femora; (3) paraprocts almost 2x as long as cerci (lateral view).
