Pseudagrion (B) sudanicum Le Roi, 1915
Blue-sided Sprite

Type locality: Meschra el Rek, Sudan


Male is similar to P. nubicum and P. torridum by (a) often found in open; widespread; (b) antehumeral stripes and postocular spots present; (c) cerci seldom dwarfed by paraprocts, if so normally not notched; (d) cerci small, not scoop-shaped, with prominent flange (long and wide wing-like internal ridge) bearing 1-2 teeth (dorsal view). However, differs by (1) antehumesal stripes brown to yellow with maturity, or pruinose, rather than green to blue; (2) apex of penis rounded rather than notched; (3) flange of cerci with 1 tooth in its apical half, rather than 1-2 including 1 in basal half; (4) paraprocts large, strongly upturned (lateral view), rather than small and weakly upturned.
