Sectiliclava cleone (Walker, 1844)

( Figs. 45, 46 )

Material examined. Psylla alni ( Fig. 8 ), on Alnus glutinosa (Linnaeus) Gaertin, Todorovići , 13.vii.2007, ex pupa 1♀.

Trophic status. Parasitoid of adult jumping plant-lice.

Hosts. Cacopsylla pyri , C. mali , C. melanoneura and C. affinis ( Trjapitzin 1989; Noyes 2017).

Distribution. Palearctic.

Diagnosis. Head and mesosoma blue golden green. Tegula yellow white or yellow, legs yellow. Fore leg with apical tarsal segment grossly enlarged, distinctly large than those of middle and hind leg. Clava on the top cut. Frontovertex and gena with long setae. The specimen matches the description published by Graham (1961) and Trjapitzin (1989).

Comments. New record for Serbia. In this study, Sectiliclava cleone was reared from an adult of Psylla alni . The species from genus Sectiliclava parasitize exclusively the adults of psyllids. So far, S. cleone has been recorded as a parasitoid of Cacopsylla melanoneura , C. affinis , C. pyri and C. mali ( Trjapitzin 1989; Noyes & Hanson 1996). Here, Sectiliclava cleone is recorded in association with Psylla alni for the first time ( Table 2).
