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 )].............
