Aethiothemis erythromelas (Ris, 1910)
Pin-tailed Flasher
Synonyms:
- scientific: Lokia erythromelas; L. berenice Fraser, 1953
Type locality: Lac Leopold II, DRC
Diagnosis
Male is similar to A. coryndoni and A. circe by (a) larger size, Hw 24-35 mm; (b) thorax more uniform, at most with black stripes along middorsal carina, humeral and dorsal half of metapleural suture, may become entirely dark and/or pruinose with age; (c) Fw triangle of 2 cells, subtriangle of 3-4, but both sometimes just of 1; (d) distal Ax in Fw usually incomplete; (e) subcostal cross-veins dark, like subcosta and median vein; (f) tibiae and femora quite uniformly brown to black; (g) Abd broad, S3 at most 1.5x as long as wide (dorsal view); (h) venter of Abd deep orange to red with maturity. However, differs by (1) labrum dark brown to black, contrasting with paler labium and anteclypeus; (2) Abd spindle-shaped, swollen at base and slender at end, rather than tapered.
