Distribution. Worlwide.

Hosts. Cicadellidae ( Guglielmino et al. 2013) .

Remarks. Fossil species of Deinodryinus were described by Olmi et al. (2010) and Guglielmino & Olmi (2011). Larvae of Deinodryinus were described by Guglielmino et al. (2017a). Leafhoppers parasitized by Deinodryinus species usually show dryinid sacs dorsally situated between the head and the prothorax ( Fig. 81A).
