Dryinus is the most common genus of Dryininae in the world. The females can be distinguished from those of other genera in this subfamily by a combination of the following characters: absence of tufts of setae on the flagellum; thin fifth segment of the fore tarsus, which is less than two times as broad as the enlarged claw; palpal formula 6/3; shorter enlarged claw, which is as long as, or shorter than, the fore tibia; and a shorter FI that is as long as, or shorter than, the pedicel ( Olmi, 1984 , 1993 ; Olmi & Bechly, 2001 ). There are 22 extant species recorded from the Palaearctic Region and 42 extant species from the Oriental Region. Their hosts have been recorded from many taxa of the Fulgoromorpha ( Guglielmino & Olmi, 1997 ).
