REMARKS

European species recorded from Austria, Germany, Denmark, Israel, Great Britain, The Netherlands, Poland, Spain and Ukraine (Nieves-Aldrey & Pujade-Villar in press).

This species has been reared from 12 gall forms (Nieves-Aldrey & Pujade-Villar in press) but it is usually present in branch galls ( A. quercusradicis female agamic, Callirhytis female agamic and Pla- giotrochus amenti female agamic). In some cases, it is very difficult to differentiate this species from S. rotundiventris because the intraspecific variability of both species is very large (Pujade-Villar in press).
