Synergus chinensis Melika, Ács & Bechtold, 2014

Figs 123–133

This species was described from north-eastern China (Beijing Province, Mentougou District, 150 km NW of Beijing), reared from unknown cynipid acorn, leaf and bud galls (Melika et al. 2004). It was later found by one of the authors (GM) in South Korea (Abe et al. 2007). Kovalev (1965) mentioned S. gallaepomiformis (Boyer de Fonscolombe) for the Far East of Russia, which was reared from asexual galls of Andricus hakonensis (= A. symbioticus, = A. attractus). We strongly doubt this identification. On the basis of the adult description given by Kovalev, these specimens belong to S. chinensis (Abe et al. 2007) . Synergus chinensis falls into a subclade with S. symbioticus and can be easily distinguished from the latter by some strong diagnostic characters given in the key and in the Diagnosis to S. symbioticus . Currently known from China, South Korea and Russia.
