TIBIALIS -GROUP

The present concept includes both groups established by Stuckenberg (1954b) for subgenus Pandasyopthalmus ( tibialis -group and longiventris -group).

Description (based on Stuckenberg, 1954b and Vockeroth, 1986): Face of both sexes often with distinct, black, median stripe. Scutum with very fine puncturation. Scutellum entirely black. Abdomen usually narrow, often subpetiolate.

Diagnostic features: Face with distinct facial tubercle ( Fig. 7 ) and with dark facial stripe in females (as in Fig. 10 ). Flagellomere about three times as long as pedicel ( Fig. 14 ). Spurious vein extending beyond or to the point of meeting of vein M with discal crossvein ( Fig. 22 ). Male genitalia: hypandrium usually with characteristic, lateral protuberances ( Fig. 63 ); lateral lobe of aedeagus reduced ( Fig. 68 ); epandrium in narrower part half length of cercus ( Fig. 65 ); ejaculatory apodeme narrow and distally with large umbrella-like fringe ( Figs 61, 62 , 100 ); postgonite much more protruded anteriorly than aedeagus ( Figs 61, 62 ); aedeagal apodeme with well-developed lateral arms ( Fig. 83 ); aedeagus with small, arm-like, lateral projections ( Figs 96–99 ).

Distribution: Main distribution in the Afrotropical region but present also in the Holarctic, Oriental, Oceanian and Neotropical regions.
