Subfamily AGATHIDINAE 



The genera in this subfamily form a rather homogeneous and uniform group. Between 1917 

 and 1945, this subfamily went under the name Braconinae due to nomenclatural problems with 

 the type-species of Cremnops and Bracon. In 1945, use of the name Agathidinae was made 

 possible by the International Commission in its Opinion 162. 



All species are endoparasites of lepidopterous larvae.
