Abstract
Two new species of Encyrtidae, Psyllaephagus phacopteron sp. nov. and Psyllaephagus garuga sp. nov. (Hymenoptera: Chalcidoidea) from Dehradun, Uttarakhand, India, that parasitize Phacopteron lentiginosum Buckton (Hemiptera: Psyllidae), a leaf-galler of Garuga pinnata Roxburgh (Burseraceae), are described. The two species are differentiated from other known Indian species of the genus through modifying a previously published key to species.
