Trithemis anomala Pinhey, 1956
Type locality: Abercorn [= Mbala], Zambia
Male is similar to T. aenea by (a) with maturity, thorax pruinose pale to dark blue, brown or black, often contrasting with largely black and pale- streaked Abd; (b) 10-12½ Ax in Fw [8½-14½]; (c) Hw base often with no or less amber; (d) anterior lamina anteriorly clothed rather evenly with hair, without distinct apical tuft; hook of hamule with generally finer tip; (e) anterior lamina with bulbous anterior profile and without knobs; genital lobe almost as long as short-hooked hamule; (f) genital lobe slender, narrower than hamule; (g) Abd mostly slender, S4 at least 3x as long as wide; (h) S4-5 and often S6-7 with double row of pale streaks. However, differs by (1) being restricted to Katanga and N Zambia; (2) dorsum of frons pale with black basal band; (3) labrum pale, marked with black T; (4) thorax dark with thick black markings; (5) Abd broader, S4 about 3x as long as wide (best seen in ventral view).
