The specimens match the description published by Nikolskaya (1952) and Trjapitzin (1989).

Comments. New record for Serbia.

Psyllaephagus procerus was reared from seven jumping plant-lice, from three genera: Camarotoscena ( C. speciosa ), Cacopsylla ( C. bidens , C. pyri and C. pyrisuga ) and Psyllopsis ( Ps. discrepans , Ps. fraxinicola and Ps. repens ).

Psyllaephagus procerus has been recorded in association with Cacopsylla sp., ( Cacopsylla pyri and Psyllopsis fraxini ), as well as the oak scale Eulecanium ciliatum (Coccidae) so far (Noyes 2017). Here, Psyllaephagus procerus is recorded in association with Cacopsylla bidens , C. pyrisuga , Psyllopsis discrepans , Ps. fraxinicola and Ps. repens for the first time ( Table 2).
