Abstract. A new genus of tryphonine ichneumonid, Boethella Bennett, n. gen. is described
from the Neotropics. Synapomorphies are provided which support the sister group relationship
of Boethella and Boethus Foerster (Tryphonini) (the latter known from the Holarctic, Neotropical
and Ethiopian regions). Boethella darlingi Bennett, n. sp. is described from eastern Brazil, B.
canilae Bennett, n. sp. (type species) is described from southern Mexico to eastern Brazil, B.
hubleyi Bennett, n. sp. is described from southeastern Brazil, B. guidottiae Bennett, n. sp. is
described from western and central Brazil and B. curriei Bennett, n. sp. is described from Peru.
