Genus Clistoabdominalis

1 Hypandrium deflected in ventral view, gonopods weakly developed............................................. 2

– Hypandrium straight in ventral view, gonopods well developed.................................................. 3

2 Phallic guide broad and flat, with small protuberances in ventral view. Base of surstyli without protuberances ( Figs 5A–E ). Cross-vein basally situated, pterostigma extremely reduced, eyes separated in males................................................................................................... Clistoabdominalis nitidifrons ( Becker, 1900)

– Phallic guide only broad at base, pointed at tip. Surstyli with protuberances at base in dorsal view ( Figs 5F–K ). Cross-vein and pterostigma different, eyes not separated in males............................ Clistoabdominalis crassus ( Bezzi, 1926)

3 Gonopods asymmetrical, outer gonopod longer; sides of phallic guide parallel, tip rounded ( Figs 6A–F ); ejaculatory apodeme and sperm pump parachute-like (as in E. flexus ). Scutellum silvery pollinose, with 7–8 pairs of strong hairs. S7 not visible without dissection. Hind femur much thicker than others and curved, no subapical spines on mid tibiae.................................................................................... Clistoabdominalis lomholdti Földvári, 2003

– Gonopods highly asymmetrical, since the outer gonopod has a large, flat, spiny lobe ( Figs 6G–L ), ejaculatory apodeme and sperm pump different. Scutellum not silvery pollinose. S7 is visible in dorsal view without dissection. Hind femur not thicker than others, two subapical (distal) spines on mid tibiae of both sexes.............. Clistoabdominalis namibiensis sp. nov.
