Ceroptres kovalevi Belizin, 1973

Ceroptres kovalevi Belizin, 1973: 37 , ♀.

Ceroptres masudai Abe, 1997: 253 , ♀ & ♂ [syn. in Lobato-Vila & Pujade-Villar (2019: 33)].

Distribution. Russian Far East ( Belizin 1973: 37; Melika 2012: 146; Pénzes et al. 2012: 56), Japan (Honshu) ( Abe 1997: 253; Abe et al. 2007: 201), South Korea ( Abe 1997: 253; Lobato-Vila et al. 2020d: 182), and China (Hebei, Henan, Liaoning, Shaanxi, Zhejiang Provinces, and Ningxia Hui Autonomous Region) ( Wang et al. 2012: 384; Pujade-Villar et al. 2016b: 20; Lobato-Vila & Pujade-Villar 2019: 33; Lobato-Vila et al. 2021b: 4).

Remarks. Andricus hakonensis ( Ashmead, 1904) was mentioned as a host gall of C. kovalevi for the first time in Pénzes et al. (2012), who stated that Wachi & Abe (2009) obtained C. masudai occasionally from these galls. However, this host gall association is neither mentioned in Wachi & Abe (2009) nor Wachi & Abe (2010), and other authors have never recorded C. kovalevi from galls of A. hakonensis . Therefore, we consider this association as doubtful and have not included it in Table 2.

Biology. Ceroptres kovalevi has been recorded from host galls in the genera Andricus , Plagiotrochus , Ussuraspis , as well as from other undetermined galls, on oaks ( Quercus ) of the sections Quercus ( Q. aliena Blume , Q. dentata Thunb. , Q. fabri Hance , Q. serrata Murray ) and Cerris ( Q. acutissima Carruth. ) ( Table 2; Lobato-Vila et al. 2021b).
