Platycypha caligata (Selys, 1853)
Dancing Jewel

Type locality: Durban, South Africa

Diagnosis

Male is similar to P. angolensis and P. lacustris 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) being widespread on streams and rivers, and sometimes at lakes; (2) sides of S1-3 and thorax reddish with maturity; (3) at most S2-5 with apical black bars. See P. caligata f. lacus for difference of this potentially distinct species at Lake Malawi. [Adapted from Dijkstra & Clausnitzer 2014]

Habitat description

Mostly rivers, but also streams and large lakes, in open landscapes or sometimes shaded by gallery forest. Usually with dead trunks or branches, often emergent vegetation and a soft (like muddy) bottom, and probably submerged roots and/or coarse detritus. From 0 to 2000 m above sea level, but mostly below 1800.
