The present concept includes some species that fit neither of Stuckenberg’s species groups, as noted by Thompson & Ghorpadé (1992), Radenković et al. (1998) and Kassebeer (1999a).

KEY TO SUBGENERA OF PARAGUS, OF THE MONOGENERIC TRIBE PARAGINI GOFFE (1952)

Description (in part based on Whittington, 1998): Eyes large in comparison with head size ( Fig. 5 ) and width of face narrow in comparison with head ( Fig. 8 ). Face of both sexes without distinct black median stripe. Puncturation of scutum and tergites coarse. Scutellum entirely black. Abdomen narrow. Tergites 3–5 usually not fused, except in Afrotropical representatives ( P. apicalis , P. manensis , P. tonkouiensis ), which show slight fusion at the extreme lateral margins. Male genitalia ( Figs 37–42 , 55–60 , 66, 67 , 78–81 , 92–95 , 101–103, 110, 111 ): shape of surstylus, hypandrium, lingula, lateral lobe of aedeagus and aedeagus variable; aedeagal apodeme of rather uniform shape, narrow, long, in lateral view L-like, in dorsal view T-like; ejaculatory apodeme small.

Diagnostic features: Face flat, with indistinct facial tubercle ( Fig. 5 ), and with pale and slightly developed facial stripe ( Fig. 8 ). Flagellomere short, less than three times as long as pedicel ( Fig. 13 ). Spurious vein ending before meeting point of vein M with discal cross-vein (as in Fig. 21 ). Male genitalia: epandrium in narrower part less than half the length of the cercus ( Figs 40, 42 ) or as long as cercus ( Fig. 38 ); ejaculatory apodema small, apical part simple, two- dimensional ( Figs 101–103 ); lateral lobe of aedeagus anteriorly protruded as much as or more than postgonites ( Figs 55–57 ); aedeagal apodeme without welldeveloped lateral arms ( Figs 79, 81 ), but with strong beak-like dorsal prolongation ( Figs 66, 67 , 78, 80 ).

Distribution: main distribution in Afrotropical and Oriental regions but present also in the Palaearctic ( Japan).
