.	Ophionines are moderate sized, orange, slender species with compressed abdomens. They have very large ocelli.
OPHIONINAE

 

	Female Acaenitinae have a large triangular projecting genital plate.
ACAENITINAE

 

	The Xoridinae are large robust black and orange woodland species with large toothed hind femora.
XORIDINAE

 

	Anomalonines are elongate slender species with compressed abdomen and a reticulated propodeum.
ANOMALONINAE

 

	Diplazontines have 3-toothed mandibles and a box-like first tergite.
DIPLAZONTINAE

 

	Ephialtines are generally robust black species with orange markings. Many have their tibiae banded in black and white. First tergite box-like with spiracle before the middle.
EPHIALTINAE

 

	The Banchinae frequently have a stalked diamond-shaped areolet and a lobe of the propodeum projecting over the mid coxae. The propodeum has few carinae, and their face is often goat-like.
BANCHINAE

 

	The Porizontines are small slender black species with compressed abdomen and clypeus confluent with face.
PORIZONTINAE

 

	The Tryphonines have a hair-margined clypeus and the first tergite bears two longitudinal parallel ridges.  Females frequently have stalked eggs projecting from their ovipositor.
TRYPHONINAE

 

	The Metopiinae have a bulging shield-like face.
METOPIINAE

 

	Most members of this large subfamily have a 5-sided areolet, a short sternaulus, and a puffy face with convex clypeus.
GELINAE

 

	Ichneumonines are generally large colorful species with 5-sided areolet, depressed abdomens, long sternaulus, and a truncate clypeus exposing the labium.
