Trithemis imitata Pinhey, 1961
Northern Fluttering Dropwing

Type locality: Buta, DRC

Diagnosis

Male is similar to T. monardi by (a) labrum at least partly pale; (b) black lines on thorax straight and slender, parallel and not merging; (c) Pt yellow to pale brown, contrasting with anterior and posterior black veins; (d) at least some basal veins yellow to red; (e) amber Hw patch includes triangle and anal loop, its distal border rather straight and perpendicular to costa, ending distal to tornus; (f) Abd slender, S4 over 3x as long as wide; (g) S8-9 largely black, with pale markings concentrated basally and/or dorsally; (h) lateral carinae of S5-7 usually marked with black; (i) S8 dorsal carina black at base, isolating pale basal spot. However, differs by (1) ranging from Kenya to Ethiopia and W Africa; (2) labium and labrum often with no or little black; (3) Hw base yellow to orange rather than deep amber, contrasting weakly with yellow veins, also with maturity; (4) venter of S7 often largely black (paler on ventral carinae), dorsum with complete black lateral band.
