(Modified from van Achterberg 2002)
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, 37, 51); hind tibia usually hardly longer than hind femur (Figs 12, 40, 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, 80, 91, 102); hind tibia usually distinctly longer than hind femur (Figs 66, 79, 92, 103); inner side of hind tibia variable, frequently without long oblique depression........................................................................................... 3
2. Veins 2-SR and 2-SR+M of fore wing absent; vein 1-SR of fore wing not or hardly differentiated because of absence of vein 1-SR+M; sclerite present between hind coxae; neck moderately to very slender and finely striate and no distinct pronotal fold, rarely with weakly developed pronotal fold and specialised (Figs 10, 18, 36, 49); outer side of hind tibia posteriorly usually without fine oblique striae and/or ventrally with fine carina; vein 2-CU1 of fore wing nearly always reduced, but sometimes complete; metapleuron slender; ovipositor sheath with or without a subapical ivory or whitish band (completely black: Figs 3, 24, 30, 43; with subapical ivory band: Figs 2, 4, 14, 21, 23, 25, 54)................................ Foenatopus Smith
- Veins 2-SR and 2-SR+M of fore wing present (Figs 72, 80)[vein 2-SR+M absent in P. reductus sp. nov. (Fig. 91)], 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, 94)..................................................................................... Parastephanellus Enderlein
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); 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); [ovipositor sheath with ivory subapical band; pronotum without transverse protuberance (Figs 56, 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)]............. Megischus Brullé
