Key to the genera of Drymini of Madagascar

1 Head almost vertical, at least 0.8 times as wide as body; eye long (length of about half head length); antenniferous tubercles curving strongly inwards, so antennae inserted much nearer to each other than inner margin of eyes. ................. Appolonius Distant, 1901

– Head nearly horizontal, at most 0.6 times as wide as body; eye much shorter than half head length; antenniferous tubercles nearly parallel, antennae erected not nearer to each other than inner margin of eyes. ........ 2

2 Basi- and distiflagellum somewhat clavate and thick; membrane at least apically dark; abdominal venter without pruinose spot. .............................................. 3

– Antenna slender and rather linear; membrane translucent; abdominal venter with large pruinose spot. ........ ....................................... Stilbocoris Bergroth, 1893

3 Profemora always unarmed; eyes with fine setae; lateral margin of pronotum carinate; hemelytra unicolorous brown or basally paler without characteristic pattern. ................................... Sinierus Distant, 1901

– Profemora usually with one or more teeth anteroventrally; eyes bare; lateral margin of pronotum from indistinct to laminate; hemelytra with conspicuous pale and dark spots. .......................................................... 4

4 Eyes always sessile and slightly protruding laterally; lateral margin of pronotum not distinct; humeral angles of pronotum rounded; basal part of ventral side of meso- and metafemora mostly armed with a tooth; basal half of corium pale. ............................................ ....... Malgadrymus Zámbó & Kondorosy , gen. nov.

– Shape of eyes very variable; lateral margin of pronotum distinct and from carinate to slightly laminate; meso- and metafemora unarmed ventrally; base of corium almost always dark. ..... Salaciola Bergroth, 1906
