Currently known only from China (Beijing Province, Mentougou District, 150 km NW of Beijing), reared from unknown cynipid acorn, leaf and bud galls ( Melika et al. 2004). This species, together with S. belizinellus and S. ishikarii , forms a distinct subclade and morphologically with all three species show some similarity. Diagnostic characters for all three species are given in the key and also in the Diagnosis to S. ishikarii and S. belizinellus .

Based on this research we can conclude that there are currently 17 valid species of Synergus in the Eastern Palaearctic, and two species with an uncertain status ( Table 2 View TABLE 2 ).

Total: 17 valid species and 2 with uncertain status
