15. Fore wing with membrane reticulate (Fig. 9); hind wing with bifid apex; segments 1 and 2 of metasoma cylindrical, slender, forming a 2-segmented petiole (Fig. 10); head with frontal and posterior surfaces separated by a pleated membrane dorsally which has a bellows-appearance when expanded

MYMAROMMATIDAE

-. Fore wing with membrane not reticulate; hind wing, if present without a bifid apex; metasoma with, at most a 1-segmented petiole; head not with membranous bellows-like structur

16

16. Tarsi 3-segmented; minute to very small insects not more than 1.2mm in length, excluding ovipositor (Figs 11,12)

-. Tarsi 4- or 5-segmented; minute to moderate sized insects varying from 0.3-45mm in length, excluding ovipositor, the majority more than 1.3mm in length

18

17. Funicle 3-segmented; gaster clearly petiolate with a distinct constriction between gaster and propodeum; mesoscutum and scutellum with distinct, raised, reticulate sculpture; frontovertex with a clearly developed transverse, V-shaped frontal suture

EULOPHIDAE (Trisecodes only)

-. Funicle at most 2-segmented; gaster sessile, broadly attached to propodeum; mesoscutum and scutellum without raised, reticulate sculpture; frontal suture of frontovertex, if present, transverse and linear

TRICHOGRAMMATIDAE

18. Frons with a straight, transverse suture a little above toruli which connects with vertical sutures adjacent to each orbit, thus forming an "H"(Fig. 13); fore wing venation frequently extremely reduced and not reaching more than about one-third of wing length (Fig. 14); hind wing elongately petiolate (Fig. 15)

MYMARIDAE

- Frons occasionally with a transverse suture, which may be straight or V-shaped, but never with vertical sutures which run adjacent to inner orbits (Fig. 16); fore wing venation always reaching more than half way along wing; hind wing not elongately petiolate

19. Hind femur swollen and with ventral teeth, hind tibia distinctly curved (Figs 17-20)

20. Visible part of prepectus very small and hardly visible, normally much smaller than tegula in side view Figs 24,25); body normally black with white, yellow or red markings, rarely metallic

-. Visible part of prepectus relatively large, normally at least about the size of a tegula in side view (Figs 26,27); body normally metallic (some Torymidae, Eulophidae and Pteromalidae)

22

21. Tegula relatively broad, not more than about 1.5X as long as broad (Fig. 28); fore wings not folded longitudinally in resting position; female with ovipositor not recurved over dorsum of gaster
