Pseudagrion (B) deningi Pinhey, 1961
Dark Sprite

Type locality: Lale Chali, Bangweulu, Zambia

Diagnosis

Male is similar to P. sudanicum by (a) often found in open; (b) cerci with prominent flange (long and wide wing-like internal ridge) bearing 1-2 teeth (dorsal view); (c) cerci at most with small basal tooth; cerci seldom dwarfed by paraprocts, if so normally not notched. However, differs by (1) ranging from N Botswana to Katanga; (2) dorsum of head and thorax all black, antehumeral stripes and postocular spots absent; (3) cerci huge, many times larger than paraprocts, scoop-shaped (lateral view).
