Key to genera of Platypyginae

1 Oral cavity with a prominent ventral sulcus, and produced posteriorly resulting in well developed postgena of either two lateral points or one single medial point ( Fig. 16 b View Figs 16–17 ) .............................................................................................................. 2

– Oral cavity without a prominent ventral sulcus; postgena normal, or if produced posteriorly, a bulbous or blunt process ( Fig. 25 View Figs 24–25 ), not pointed .............................. 4

2 Discal cell closed distally by crossvein ( Fig. 37 View Figs 35–38 ); postgena developed into two lateral processes or posterior end of sulcus squared ( Fig. 16 b View Figs 16–17 ) ........................... 3

– Discal cell open distally, not closed by crossvein ( Fig. 35 View Figs 35–38 ); postgena developed into single point ............................................................... Cephalodromia Becker

3 Vein R1 short, ending in costa before level of r-m crossvein ( Fig. 37 View Figs 35–38 ); vein Sc complete, ending in costa; first antennal flagellomere with basoventral and apicoventral bulges ( Fig. 12 View Figs 10–13 ); crossvein r-m at middle of discal cell ( Fig. 37 View Figs 35–38 ); spermathecae with long sclerotised apical duct leading to spherical reservoir ( Fig. 43 View Figs 40–44 ) ............................................... Ahessea Greathead and Evenhuis , gen. n.

– Vein Sc incomplete, no ending in costa; first antennal flagellomere shaped as in Fig. 6 View Figs 4–9 , without such bulges basally or apically; crossvein r-m at extreme base of discal cell ( Fig. 38 View Figs 35–38 ); spermathecae with thin, membranous apical ducts leading to kidney-shaped reservoir ( Fig. 44 View Figs 40–44 ) ............................................ Cyrtisiopsis Séguy

4 Discal cell closed distally by crossvein ..................................... Platypygus Loew

– Discal cell open distally, not closed by crossvein.......................... Cyrtosia Perris
