Nesciothemis minor Gambles, 1966
Small Blacktail

Type locality: Ka Yima, Sierra Leone

Diagnosis

Male is similar to N. farinosa and N. pujoli by black S7-10, often with yellow streaks. However, differs by (1) more partial to running waters from CAR to W Africa; (2) smaller size, Hw 27-29 mm, rarely up to 31 mm; (3) labrum pale and tibiae black with pale streaks even with maturity; (4) Abd pruinose to end of S6, rather than at most to the base of that segment. Note, however, that males of N. farinosa from south-western Africa (e.g. Angola, Botswana) with pruinosity to S7 or even S8 have been confused with N. minor, and may represent another species.
