Aciagrion dondoense Dijkstra, 2007
Opal Slim

Synonyms:

  • scientific: A. congoense sensu Pinhey, 1972 nec (Sjöstedt, 1917)

Type locality: Pemba Island, Ngezi Forest, Tanzania

Diagnosis

Male is similar to A. zambiense by (a) larger size, Hw 19-22 mm; (b) dorsum of head pale with some black traces; (c) thorax largely pale; (d) cerci distinctly longer than paraprocts, with broad or rounded apex; (e) basal tooth of paraprocts directed straight upwards. However, differs by (1) ranging from NE Tanzania to NE South Africa; (2) cerci about as long as S10, with squarish apex and rather small tooth-like ventral process placed close to base.
