description: Key to Old World genera of Sapyginae
1. Dorsal margin of clypeal disk directly connected to frontal shelf or carina of frons medially. Hind wing vein r-m clearly angled (vein indicated by arrow in Fig. 4B)...................................................................... 2
- Dorsal margin of clypeal disk broadly separated from frontal shelf or carina of frons by distinct suture. Hind wing vein r-m straight or slightly curved.............................................................................. 3
2. Antennal flagellum short, F5–9 distinctly less than 1.5 × as long as broad (Fig. 2A). Occipital carina present laterally. Propodeum anterolaterally with a large polished area (Fig. 3B). Vein Rs of fore wing approximately half as long as vein M; vein 2Cu + 2cu-a not indented at junction with vein 3Cu (Fig. 4A); vein 1Rs slightly less than twice as long as vein r-rs; veins 2Rs and 3Rs of subequal length; second submarginal cell not more than 1.5 × as long as high (Fig. 4A). T2–6 densely coriaceous, without distinct punctures (Fig. 3C). Pubescence of tergites dorsally long and dense, suberect (Figs 1A, 3C)............................................................................................... Dasysapyga van Loon, gen. nov.
- Antennal flagellum long, all flagellomeres more than 1.5 × as long as broad. Occipital carina absent. Propodeum laterally coarsely and rather closely sculptured, at most with a narrow longitudinal polished area. Vein Rs of fore wing much shorter than M; vein 2Cu + 2cu-a distinctly indented at junction with vein 3Cu; vein 1Rs much more than twice as long as vein r-rs; veins 2Rs longer than 3Rs; second submarginal cell at least twice as long as high. T2–6 largely polished, with sparse punctures. Pubescence of tergites dorsally very short and sparse, erect................................. Parasapyga Turner, 1910
3. Fore wing vein 2r-m more or less straight medially. Tarsal claws with or without submedian tooth. (genus Sapygina Costa, 1887 s.l.)................................................................................................ 4
- Fore wing vein 2r-m distinctly sinuate. Tarsal claws always with a submedian tooth................................. 5
4. Mandible with basal tooth perpendicular and clearly separated from mandibular apex, often much larger than subapical tooth. Afrotropical............................................................... subgenus Sapygella Benoit, 1950
- Mandibular teeth located in close proximity, basal most tooth not perpendicular or distinctly larger than subapical tooth. West Palaearctic.................................................................. subgenus Sapygina Costa, 1887
5. Anterolateral surface of propodeum with a large polished area.................................................. 6
- Metapectal-propodeal complex more or less entirely punctate, without large polished area............................ 7
6. Male F 5–11 with polished concavities along each ventral tyloid. Basitarsus of middle tarsus twice as long as combined length of tarsomeres 2–4. East Palaearctic, Oriental ..................................... Polochridium Gussakovskij, 1932
- Male F5–11 without polished concavities along each ventral tyloid. Basitarsus of middle tarsus much less than twice as long as combined length of tarsomeres 2–4. West Palaearctic................................... Asmisapyga Kurzenko, 1994
7. Antennal flagellum distinctly clavate, gradually widening towards apex. Apical two flagellomeres of male distinctly swollen and with a deep ventral sulcus. Eyes in frontal view nearly parallel-sided medially. 1r-m rather strongly angled towards 1m-cu, resulting in an acute angle relative to Rs. Dorsal surface of propodeum longer than width of propodeum. West Palaearctic.................................................................................... Monosapyga Pic, 1920
- Antennal flagellum not clavate. Apical flagellomere of male reduced, distinctly shorter than preceding flagellomere (except subgenus Polosapyga Kurzenko, 1994 of Sapyga). Eyes in frontal view evenly convex. 1r-m not strongly angled towards 1m-cu and making an almost right angle with Rs. Dorsal surface of propodeum shorter or about as long as width of propodeum. Holarctic............................................................................................ 8
8. Malar space longer than diameter of anterior ocellus. Vein 1cu-a of fore wing arising distinctly distad of M from M+Cu. Second submarginal cell elongate, more than twice as long as high. Female S6 with a longitudinal median carina................................................................................................ Polochrum Spinola, 1805
- Malar space at most as long as diameter of anterior ocellus. Vein 1cu-a usually arising more or less interstitial with M from M+Cu. Second submarginal cell short, less than twice as long as high. Female S6 without longitudinal median carina ......................................................................................... Sapyga Latreille, 1796
