Synergus japonicus WALKER, 1874

The most abundant Synergus species, reared from cynipid oak galls, collected by us at the Xiaolongmen Biological Station ( China, Beijing Province, Mentougou District, 150 km NW of Beijing) during July 2002, from three unidentified Quercus species was Synergus japonicus . We reared this species from all three mentioned oak galls: “ Andricus sp. 1 ”, “ Andricus sp. 2 ”, “ Andricus sp. 3 ”, and from asexual galls of Andricus mukaigawae (MUKAIGAWA, 1913). Both species, Andricus mukaigawae and Synergus japonicus are listed for the Chinese fauna for the first time. Synergus japonicus belongs to Section I (MAYR 1872) of Synergus , which is characterized by a band of punctures on the posterior end of metasomal terga 2+3, reaching the ventral edge of the tergum, while the two newly described species belong to Section II (MAYR 1872).
