Cacopsylla peregrina   , from Crataegus monogyna, Ilinci   , 20.v.2006. ex pupa 5♀♀ 1♂ as hyperparasitoid. Cacopsylla pyri   , from Pyrus communis, Radmilovac   , 07.v.2007. ex pupa 16.v.2007. 3♀♀ as hyperparasitoid; Novi Sad, 03.v.2008. ex pupa 1 ♂. 07.ix.2008. ex pupa 3♀♀; ex pupa 1♀ 1♂. Psyllopsis fraxinicola   , from Fraxinus excelsior, Zemun-Nova Galenika   , 31.v.2007. ex pupa 3♀♀ as hyperparasitoid.

Trophic status. Parasitoid or hyperparasitoid.

Hosts. Psyllidae   ( Cacopsylla peregrina   , C. pyri   ) (Noyes 2017).

Distribution. West Palearctic and Central Asia.

Diagnosis. Flagellar segments regularly enlarged at apex. Sculpture on scutellum rougher than sculpture on mesoscutellum. Scutellum matt. The specimens are in accordance to the description by Trjapitzin (1989) and Japoshvili (2007).

Comments. In this study, Syrphophagus taeniatus   was reared from four species of jumping plant-lice: C. bidens   , C. peregrina   , C. pyri   and Psyllopsis fraxinicola   ( Table 2).

S. taeniatus   is reported as a primary as well as secondary parasitoid. It was cited by Noyes (2017) as a primary parasitoid of the nymphs of C. peregrina   and C. pyri   . However, Herard (1986) found that S. taeniatus   is a hyperparasitoid. He reared S. taeniatus   from nymphs of C. pyri   that had already been parasitized by Prionomitus mitratus   .

In Serbia, Grbić et al. (1989) reared S. taeniatus   from nymphs of C. pyri   , without clearly stating whether it was a primary or a hyperparasitoid.

In this study, Syrphophagus taeniatus   is recorded in association with Cacopsylla bidens   and Psyllopsis fraxinicola   for the first time. In several cases, we found that S. taeniatus   was a hyperparasitoid when psyllid hosts were C. pyri   , C. peregrina   and Ps. fraxinicola   .
