Platycypha lacustris (Förster, 1914)
Forest Jewel

Type locality: Entebbe, Uganda

Diagnosis

Male is similar to P. caligata by (a) humeral and metapleural stripes narrow, about as wide as hind femur is thick, black of mesepimeron usually clearly dissected by pale ‘posthumeral’ stripe; (b) dorsum of S2-10 blue; (c) paraprocts less than half as long as cerci (lateral view). However, differs by (1) favouring forested streams and rivers; (2) sides of S1-3 and thorax greenish, rather than reddish with maturity; (3) S2-7 and sometimes S8 with apical black bar.
