Western Elf

Type locality: Ghana, no locality data available.

Diagnosis

Male is typical of the scarcer rainforest (from W Kenya to W Africa) Tetrathemis species by (a) interpleural stripe runs from wing base to metastigma, parallel to metapleural and humeral stripes, sometimes partly fused with humeral; (b) never pruinose and wings always clear, although base may be yellow; (c) arculus usually at or distal to Ax2; (d) Hw supratriangles with 1 cross-vein; (e) bridge spaces with 1 cross-vein; (f) lateral pale spot on S1 adjoined to similar spot on S2; (g) cerci less than 3x as long as S10, rather straight. Close to T. ruwensoriensis by combination of (h) S10 at most as long as S9 (dorsal view); (i) cerci equal to or shorter than epiproct; (j) epiproct triangular, with rather narrow apex; but (1) cerci divergent, apices angulated; (2) epiproct less than 1.2x as long as cerci.
