1. First subdiscal cell of fore wing comparatively wide basally, wider than first discal cell or vein 1-SR of fore wing not differentiated and first discal cell absent because of absence of vein 1-SR+M ( Figs 11 View FIGURES 5–12 , 37 View FIGURES 33–40 , 51 View FIGURES 45–52 ); hind tibia usually hardly longer than hind femur ( Figs 12 View FIGURES 5–12 , 40 View FIGURES 33–40 , 52 View FIGURES 45–52 ); inner side of hind tibia with a long oblique depression..................................... 2

- First subdiscal cell of fore wing comparatively narrow basally, about as wide as first discal cell or narrower and vein 1-SR of fore wing differentiated with first discal cell present because of presence of vein 1-SR+M ( Figs 1 View FIGURE 1 , 80 View FIGURES 74–81 , 91 View FIGURES 85–92 , 102 View FIGURES 96–103 ); hind tibia usually distinctly longer than hind femur ( Figs 66 View FIGURES 66–71 , 79 View FIGURES 74–81 , 92 View FIGURES 85–92 , 103 View FIGURES 96–103 ); inner side of hind tibia variable, frequently without long oblique depression........................................................................................... 3

( Fig. 91 View FIGURES 85–92 )], sometimes only pigmented; vein 1-SR of fore wing distinctly differentiated because of presence of vein 1-SR+M; sclerite absent between hind coxae; neck short and comparatively robust, without pronotal fold or transverse carinae; outer side of hind tibia with distinct oblique striae ventrally (but often fine or only ventrally distinctly developed and frequently with some rugulosity and/or apical half of tibia with ventral carina more or less developed), rarely without striae or ventral carina; vein 2-CU1 of fore wing completely developed; metapleuron robust; ovipositor sheath without ivory or whitish subapical band ( Figs 83 View FIGURES 82–83 , 94 View FIGURES 93–94 ).....................................................................................

3. Hind tarsus of female with five tarsomeres; hind femur distinctly slender and elongate, coarsely striate, ventrally with 2–3 large teeth, rarely with 4 teeth ( Fig. 103 View FIGURES 96–103 ); inner side of hind tibia only with a short narrow oblique groove below a small convexity..................................................................................... Stephanus Jurine

- Hind tarsus of female with three tarsomeres; hind femur comparatively robust and less elongate, largely smooth and with some punctures, ventrally with 2 large teeth; inner side of hind tibia usually with wide submedial ventral carina and or with oblique striae ventro-posteriorly ( Fig. 66 View FIGURES 66–71 ); [ovipositor sheath with ivory subapical band; pronotum without transverse protuberance ( Figs 56 View FIGURE 56 , 71 View FIGURES 66–71 ); temple without pale yellowish streak behind eye, at most with a ventral patch; outer side of hind tibia without oblique striae or rugulosity; vein 1-M of fore wing 3.5–8.0 × as long as vein 1-SR ( Fig. 1 View FIGURE 1 )].............
