22. Fore wing with charactersitic venation: stigmal vein very short with uncus hardly separated from the well-developed postmarginal vein (Figs 31,32); hind coxa elongate, at least about 2x as long as fore coxa (Figs 31,32); tarsi always 5-segmented; flagellum always with more than 6 segments; gastral petiole virtually never longer than broad; female of vast majority of species with ovipositor well-exserted (Fig. 31)

-. Not with above combination of characters; either stigmal vein of fore wing elongate with uncus well separated from postmarginal vein (Fig. 33), or hind coxa not so enlarged (Figs 34,35), or tarsi are 4-segmented, or flagellum not with more than 6 segments, or gastral petiole clearly longer than broad; majority of species with ovipositor not or hardly exserted, although many species with a well-exsererted ovipositor are known (Figs 34,35)

23. Gaster coarsly sculptured (Fig. 36) and with cercal bristles reduced to short tubercles; notauli shallow; female with ovipositor not or hardly exserted

ORMYRIDAE

Fig. 36 Fig. 37

- Gaster never with rough sculpture, more or less smooth (Fig. 37), with cercal bristles elongate; notauli deeply impressed; female with exserted part of ovipositor normally at least about one-quarter as long as gaster (Fig. 37)

TORYMIDAE

24. Species associated with fruit of figs; fore and hind legs with femora and tibiae almost always relatively large in relation to those of the mid leg which are unmodified and relatively slender (Figs 38-41a). [Females normally with a well-exserted ovipositor; males normally with wings absent or very reduced.]
