Type species: Paragus pusillus Stuckenberg, 1954 : Transactions of the Royal Entomological Society of London, 105 (17): 401 .

Description (based on Stuckenberg, 1954b): Mediumsized to large species (5–7.5 mm) with oval and compact abdomen (broader in the female) exhibiting unusually large tergite 2. Male holoptic. Face of male yellow, with black lower margin and more or less distinct, dark median stripe. Face of female with median black stripe. Scutum shining black, with variably coloured reflections, covered with pale pilosity. Scutellum serrate, large, yellow anteriorly and black in posterior half. Tergites 3–5 usually with broad and distinct, white pruinose stripes. Male genitalia ( Figs 35, 36, 43, 44): surstylus elongated, usually narrowest medially; hypandrium with deep lateral emargination, usually with marginal prolongations; lingula usually well developed, ‘finger-like’ in lateral view ( Fig. 43), sometimes very small ( Fig. 44); aedeagal apodeme with long and well-developed lateral arms ( Figs 72, 73); postgonite plate-like, with much short pile in anterior part ( Fig. 107); lateral lobe of aedeagus large, anteriorly most protruded part of aedeagus ( Figs 43, 44); ejaculatory apodeme usually very large ( Fig. 105); aedeagus medium sized and very broad medially ( Figs 90, 91).

Diagnostic features: Eyes with stripes of pile (as in Fig. 9). Face with distinct facial tubercle ( Fig. 6). Scutum usually with long, submedian dusted stripes reaching the posterior margin ( Fig. 15). Scutellum with conspicuous teeth on posterior margin ( Fig. 18). Spurious vein ending before meeting point of vein M with discal cross-vein (as in Fig. 21). Abdomen short and elliptical; tergite 1 large, longer than distance between its posterior margin and the posterior margin of tergite 2 ( Figs 23, 29). Tergites 1–5 completely fused, at least laterally. The posterior margins of tergites 3 (female) and 4 (in both sexes) visible except laterally ( Figs 23, 29). Male genitalia: minis large, lateral arms of minis short ( Fig. 35); epandrium in narrower part slightly shorter than or of same length as cercus ( Fig. 36); ejaculatory apodeme large, umbrella-like ( Figs 43, 105); lateral lobe of aedeagus strongly fused with aedeagal apodeme ( Fig. 69); aedeagus in ventral view ‘amphora-like’, very broad, petiolate basally ( Figs 90, 91); postgonite plate-like, pilose ( Fig. 107).

Distribution: mainly Afrotropical and Oriental regions but also present in the Oceanian and Palaearctic regions ( Turkey).
