Key to Meristomerinx and related genera of Afrotropical Pachygastrinae

1 Scutellum with two spines ..................................................................................................... Meristomeringina James

- Scutellum without spines .............................................................................................................................................. 2

2 At least part of eighth antennal flagellomere forming a bare, arista–like style, the basal portion of which can be thickened and heavily, uniformly setose ....................................................................................................................... 3

- Eighth antennal flagellomere without any part slender or arista-like........................................................................... 5

3 Eighth antennal flagellomere entirely slender and arista-like, basal portion without any obvious stiff, dense setae ( Woodley 1997: figs. 1–3) ..................................................................................................... Meristomerinx Enderlein

- Eighth antennal flagellomere with basal part thickened, with obvious stiff, dense setae, only apical portion aristalike................................................................................................................................................................................. 4

4 Basal one-third or less of eighth flagellomere thickened and with stiff, dense setae ( Woodley 1987: fig. 1); thoracic pleura and at least part of abdominal tergites yellowish-orange; male with eyes widely separated .. Ashantina Kertész

- Basal one-half or more of eighth flagellomere thickened and with stiff, dense setae; thoracic pleura and abdominal tergites largely black, except for translucent spot on basal two tergites; male with eyes contiguous ............................ ................................................................................................................................................ Hermetiomima Grünberg

5 Antenna distinctly longer than head; flagellomeres 7 and 8 of antenna slightly to moderately thickened and completely covered with obvious stiff, dense setae; eighth flagellomere at least twice as long as seventh.......................... ..................................................................................................................................................... Dolichodema Kertész

- Antenna distinctly shorter than head ( Figs. 1, 2 ); flagellomeres 7 and 8 of antenna short, conically tapered, their diameter less than preceding flagellomeres and without obvious stiff, dense setae ( Figs. 5, 6 ); eighth flagellomere minute, shorter than seventh in male, subequal to seventh in female .................................
