Subfamily BRACHYCISTIDINAE 



Brachycistidinae exhibit very pronounced sexual dimorphism, males being fully winged and 

 females wingless and with modified thorax. Positive sex associations have been established only 

 in Brachycistis Fox. Eventually there will be considerable generic synonymy because the 

 remaining males and females are assigned to separate genera.
