(adapted from Khalaim, 2007)

1A	First metasomal segment with glymma joined by a furrow to ventral part of postpetiole (Fig. 1) ....2

1B	First metasomal segment without glymma (Fig. 2), or with isolated glymma (Fig. 3) ...3

2A	Thyridia much longer than wide. Sternaulus distinct, almost as long as mesopleuron... Probles

2B	Thyridia short, at the most as long as wide. Sternaulus of varying length, or absent... Tersilochus

3A	Propodeal spiracle large (Fig. 4). Propodeum with basal keel (sometimes indistinct) (Fig. 4). Second recurrent vein postfurcal (as in Fig. 6)... Meggoleus

3B	Propodeal spiracle not enlarged (Fig. 5). Propodeum with basal keel, furrow or area (Fig. 5). Second recurrent vein postfurcal, interstitial or antefurcal... 4

4A	Propodeum with wide basal furrow or area (Fig. 5). Second recurrent vein interstitial (Fig. 20) or antefurcal (Fig. 19). First metasomal segment without distinct glymma (as in Fig. 2)... 5

4B	Propodeum with basal keel (as in Fig. 4). Second recurrent vein postfurcal or rarely interstitial. First metasomal segment without glymma, or sometimes with distinct glymma (Fig. 3)... 7

5A	Maxillary palpus much longer than height of head (Fig. 8). Second recurrent vein antefurcal (Fig. 19)... Heterocola

5B	Maxillary palpus at the most half as long as height of head. Second recurrent vein interstitial (Fig. 20) or antefurcal... 6

6A	Nervellus of hindwing strongly reclivous (Fig. 11). Inner margins of eyes of male strongly convergent dorsally (Fig. 9)... Allophrys

6B	Nervellus of hindwing vertical or moderately reclivous (Fig. 10). Inner margins of eyes of male parallel... Phradis

7A	Brachial cell of forewing closed at apex, posterior part of postnervulus present except for a narrow bulla (as in Figs 19, 20)... Diaparsis

7B	Brachial cell of forewing widely open at apex, posterior part of postnervulus absent (Figs 6, 7)... 8
