Pseudagrion (A) salisburyense Ris, 1921
Slate Sprite

Type locality: M'Fongosi, Natal, South Africa

Diagnosis

Male is similar to P. spernatum by (a) mostly species of open or montane habitats; (b) labrum green to blue; (c) frons, Abd and often head and/or thorax usually pruinose; (d) thorax extensively black, usually with distinct (sometimes pruinose) antehumeral stripes; (e) legs usually at least broadly marked with black. Tarsal claws with small hook or notch beside main hook; (f) cerci short, only slightly longer than paraprocts (lateral view), lower branch only slightly longer than upper, gap between them mere notch or slit, flange of lower branch usually rather prominent and oblique relative to main axis of cercus (dorsal view); (g) paraprocts pointed and up-turned. However, differs by (1) smaller size, Hw 18-23 mm; (2) postclypeus blue with black base, rather than all black; (3) lower branch of cerci rather horizontal (lateral view).

Habitat description

Mostly streams, but also rivers and standing waters, in open landscapes, but sometimes shaded by gallery forest. Often calmer sections (like pools) with emergent vegetation and a sandy, soft (like muddy) and/or possibly gravelly bottom. From 0 to 2600 m above sea level, but mostly between 600 and 1700.
