This is a large genus of Neotropic, Holarctic, Oriental, and Ethiopian distribution. The majori- 

 ty of the species occur in the Holarctic Region. Most species presumably parasitize sawflies, but 

 a European species identified as L. clypeatus (Zetterstedt) has been reared from two species of 

 the primitive microlepidopteran family Eriocraniidae and L. mnemonicae (Rohwer) has also 

 been reared from an eriocraniid.
