Nesciothemis farinosa (Förster, 1898)
Eastern Blacktail

Type locality: Komatipoort, South Africa

Diagnosis

Male is similar to N. pujoli by (a) larger size, Hw 31-35 mm, rarely down to 29 mm; (b) labrum black, often with paler border, and tibiae all black with maturity; (c) Abd pruinose to base of S6, rarely to base of S8 in south; (d) S7-10 black, often with yellow streaks. However, differs by (1) ranging from Arabia to South Africa; (2) hollow of hamule lobe deep and narrow, fitting ridge less than 3x (lateral view); (3) ridge along border of lobe of hamule continues below gap between lobe and hook; (4) at least more than half of S4 pruinose, often S5 entirely so, occasionally to base of S8.
