Trithemis stictica (Burmeister, 1839)
Jaunty Dropwing
Type locality: Natal, South Africa
Diagnosis
Male is similar to T. morrisoni by (a) vertex and dorsum of frons metallic blue, with no hint of purple; (b) pruinosity of thorax in life pale blue; (c) 10-12½ Ax in Fw [8½-14½]; (d) Hw often with yellow wash centred on anal loop; (e) anterior lamina anteriorly clothed rather evenly with hair, without distinct apical tuft; hook of hamule with generally finer tip; (f) genital lobe slender, narrower than hamule; (g) Abd mostly slender, S4 at least 3x as long as wide; (h) S4-7 with single or no row of streaks. However, differs by (1) being widespread, often in highlands; (2) eyes in life uniformly bluish, rather than two-toned; (3) Hw base clear rather than often amber; (4) penis with two gradually narrowing incurved processes.

Habitat description
Mostly streams, but also rivers and standing waters, in open landscapes, but sometimes in open areas in forest or shaded by gallery forest. Usually with emergent vegetation and often a sandy, soft (like muddy) and/or probably gravelly bottom, probably especially calmer sections (like pools) with coarse detritus. From 0 to 2200 m above sea level, but mostly below 1900.
