Review of the sawfly genus Empria (Hymenoptera, Tenthredinidae) in Japan

The following eleven Empria species are reported from Japan: E. candidata (Fallén, 1808), E. japonica Heidemaa & Prous, 2011, E. liturata (Gmelin, 1790), E. loktini Ermolenko, 1971, E. plana (Jakowlew, 1891), E. quadrimaculata Takeuchi, 1952, E. rubicola Ermolenko, 1971, E. tridens (Konow, 1896), E. tridentis Lee & Ryu, 1996, E. honshuana Prous & Heidemaa, sp. n., and E. takeuchii Prous & Heidemaa sp. n. The lectotypes of Poecilosoma pallipes Matsumura, 1912, Empria itelmena Malaise, 1931, Tenthredo candidata Fallén, 1808, and Tenthredo (Poecilostoma) hybrida Erichson, 1851 are designated. Empria itelmena Malaise, 1931 (syn. n.) is synonymized with E. plana (Jakowlew, 1891). Poecilosoma pallipes Matsumura, 1912, previously assigned to Empria, is transferred to Monsoma, creating Monsoma pallipes (Matsumura, 1912), comb. n. Results of phylogenetic analyses using mitochondrial (COI) and nuclear (ITS1 and ITS2) sequences are also provided.
