Pseudagrion (B) assegaii Pinhey, 1950
Assegai Sprite

Type locality: Transvaal, South Africa

Diagnosis

Male is similar to P. lindicum 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) upper branch of cerci hooked, but inner border of lower branch smooth; (f) paraprocts never with dorsal knob (lateral view). However, differs by (1) often in the open, and ranging from N South Africa and N Botswana to Zambia, also Uganda; (2) smaller size, Hw 17-19 mm; (3) dorsum of S2 with single-pronged black marking, rather like spearhead, rather than with double-pronged black marking; (4) apex of penis with deep and wide notch between large apical lobes, rather than being rounded or squarish; (5) lower branch of cerci short (lateral view), rather than long and finger-like.
