Key to Malagasy Cremastinae genera

1 Fore wing with areolet closed, petiolate. Clypeus small with a tongue-like apical lobe. Mandibles very broad at base and tapered at apex, the teeth blunt or almost unindented ( Fig. 7 ).................................... Eurygenys Townes

- Fore wing with areolet open, clypeus and mandibles different.................................................. 2

2(1) Fore wing with Rs-m basal to 2m-cu by at least about the length of Rs-m ( Fig. 4 b). Hind femur often swollen, with a tooth beneath (always in males, often in females)................................................................ 3

- Fore wing with Rs-m opposite or basal to 2m-cu by less than the length of Rs-m ( Fig. 4 a). Hind femur simple in both sexes...................................................................................................... 4

3(2) Hind wing with Cu1 pigmented and reaching the wing margin. Ovipositor rather stout, slightly upcurved, its tip straight ( Fig. 8 )..................................................................................... Fafana gen. nov.

- Vein Cu1 of hind wing spectral. Ovipositor thin, its tip usually distinctly sinuate...................... Pristomerus Curtis

4(2) Ventral margins of tergite I touching, thus enclosing and hiding most of the sternite ( Fig. 5 a)........... Temelucha Förster

- Ventral margins of tergite I separated their entire length ( Fig. 5 b)............................................... 5

5(4) Occipital carina incomplete above. Male genital gonosquama with a long ventral asymmetric lobe ( Fig. 6 )................................................................................................. Cremastus Gravenhorst

- Occipital carina complete or narrowly incomplete above. Male gonoforceps without ventral lobe....................... 6

6(5) Lower tooth of mandible more than 1.5x longer than upper ( Fig. 9 )........................... Pimplomorpha Cameron

- Lower tooth a most 1.5x longer than upper ( Figs. 12–13 )........................................ Trathala Cameron
