Following the elevation of Cenocoeliini to subfamily status in 1984 and the transfer of Brachistini and Diospilini to Brachistinae in 2011, the subfamily now comprises three tribes: Helconini, Ussurohelconini, and Vervoortihelconini, with approximately 12 genera. Members are known to parasitize wood-boring , particularly .
