Trithemis arteriosa (Burmeister, 1839)
Red-veined Dropwing

Synonyms:

  • scientific: T. jacksoni Pinhey, 1970

Type locality: Natal, South Africa

Diagnosis

Male is similar to T. imitata and T. monardi by (a) labrum at least partly pale; (b) at least some basal veins yellow to red; Pt yellow to dark reddish brown; (c) hamule with short, strongly curved hook; (d) Abd slender, S4 over 3x as long as wide. S8-9 largely black, with pale markings concentrated basally and/or dorsally; (e) lateral carinae of S5-7 usually marked with black. However, differs by (1) black lines on thorax usually irregular and thick, curving backwards to near or touch each other; (2) Pt reddish to almost black (rather than yellow to pale brown), contrast with anterior and often posterior black vein usually weak; (3) amber Hw patch often excludes triangle and sometimes even anal loop, its distal border roundly curved towards tornus; (4) S8 dorsal carina all pale (rather than being black at base), at most black trace at base, merging with pale basal spot, or entire dorsum pale.
