Notogomphus praetorius (Selys, 1878)
Yellowjack Longleg

Type locality: Transvaal, South Africa

Diagnosis

Male is similar to N. zernyi by (a) ranging from S Tanzania to South Africa; (b) face all pale, at most with thin dark line on frons or at base postclypeus; (c) antehumeral stripe broad; (d) interpleural suture usually with black stripe between metastigma and wing base; (e) postdorsal stripes separate from pale area of middorsal carina; (f) costa pale; (g) ventral teeth of cerci directed downwards, not visible in dorsal view. However, differs by (1) ranging from South Africa to Katanga and Malawi; (2) larger size, Hw 29-32 mm; (3) pale ‘posthumeral’ stripe present posterior to humeral stripe; (4) postdorsal stripe forms continuous band across mesepisternum; (5) cerci diverge at base, their elongate apices bent abruptly inwards, rather than cerci being parallel; (6) ventral tooth of cerci small rather than large.
