TETRACAMPIDAE

29. Gaster distinctly constricted at its junction with propodeum (Figs 49-51); fore wing often with postmarginal and stigmal veins long and distinct, but in some (eg Tetrastichinae) postmarginal vein almost absent(Fig. 52); body frequently at least partly metallic; notauli, if complete normally distinctly curved; fore tibial spur usually straight

Gaster, at its base, about as broad as propodeum and not distinctly constricted at this point (Figs 53-55); fore wing with postmarginal vein absent or almost always so and stigmal vein very short; body non-metallic, usually black, dark brown or yellowish; notauli complete and straight; fore tibial spur curved

APHELINIDAE

30. Antenna with a very long unsegmented club, female funicle composed of three or four indistinct and strongly transverse funicle segments, male funicle with from one to four anelliform segments (Figs 56-57); body mostly shining black (Figs 57,58), occasionally yellow, red or brown; gaster sessile; axillae not distinctly marked off from the scutellum, the two together forming a strongly transverse band about three times as broad as long; propodeum with a large central triangular area which is shiny (Fig. 56)
