Taxonomic review of the genus Empria Lepeletier & Serville (Hymenoptera, Tenthredinidae) in South Korea: morphological and molecular identification of two new species

Abstract

The sawfly genus Empria Lepeletier & Serville (Hymenoptera: Tenthredinidae: Allantinae) is reviewed in South Korea and four species are reported as new in the country: Empria lycroi Prous & Park, sp. nov. (also Russia); E. nigroterga Park & Lee, sp. nov. (also Russia); E. wui Wei & Nie (also Japan); and E. zhangi Wei & Yan (also Russia). Tenthredo magnicornis Eversmann, 1864, syn. nov. is treated as a synonym of E. candidata (Fallén, 1808). A key to the six species currently known from South Korea and photographs of the diagnostic characters for each species are presented. In addition, phylogenetic analysis based on one mitochondrial (COI) and two nuclear (NaK, POL2) genes are reported for 20 species of Empria.
