Notogomphus zernyi (St. Quentin, 1942)
Type locality: Lupembe Mt, Tanzania
Male is similar to N. praetorius 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 S Tanzania to Zimbabwe; (2) smaller size, Hw 25-28 mm; (3) postdorsal stripe forms elongate band isolated by black of mesepisternum; (4)‘posthumeral’ stripe absent; (5) cerci more or less parallel, rather than diverging at base; (6) ventral tooth of cerci large rather than small.
