Pseudagrion (B) coeleste Longfield, 1947
- scientific: P. umsingaziense Balinsky, 1963
Type locality: Mupa, Angola
Male is similar to P. glaucescens and P. helenae, by (a) face green or blue, sometimes yellowish; (b) S8-9 seldom with narrowly black apical border, often all blue; (c) cerci without flange; (d) cerci at most with small basal tooth; cerci seldom dwarfed by paraprocts, if so normally not notched; (e) inner borders of both upper and lower branch of cerci angled or toothed, thus cerci appearing double-hooked (dorsal view); (f) paraprocts never with dorsal knob (lateral view). However, differs by (1) ranging from N South Africa and N Botswana to Zambia; (2) smaller size, Hw 16-21 mm; (3) penis with deep apical notch and small lateral points, rather than with shallow apical notch and no lateral points; (4) cerci almost as long as S10, angle of inner border of lower branch of cerci rather obtuse (dorsal view), rather than with sharp angle.

Standing waters and rivers, but possibly also large lakes and flowing channels in marshes, in open landscapes, but sometimes shaded by gallery forest. Usually with emergent and often aquatic vegetation. From 0 to 1600 m above sea level.
