Abstract

A review of eleven Palaearctic species of the genus Synacra Foerster is provided, four of which are described as new to science: S. azepylopriasp. n. (Russia: Kunashir Island; Japan: Honshu Island), S. compressigastrasp. n. (Russia: northern European part and East Siberia (Yakutia), southern Far East), S. giganteasp. n. (Russia: Primorskii Territory) and S. tobiasisp. n. (South Kazakhstan). The following new synonymy is established: Synacra Foerster, 1856 = Foeldia Szabó, 1974, syn. n.; Synacra sociabilis (Kieffer, 1904) = Foeldia triclavicanthiger Szabó, 1974, syn. n. All the Palaearctic species of Synacra are keyed and illustrated.
