The subfamily Sterictiphorinae which include 324 species from 26 genera is widespread group of sawfly. Most recorded species of Sterictiphorinae distributed in the Palaearctic, Nearactic, Oriental and Afrotropic regions. Among them, only 20 species have been reported from the Eastern Palaearctic region. Unfortunately, this group is very poorly studied in Korea. In the Korean fauna were reported only one species, Sterictiphora tanoi Togashi 1997(Togashi, 1997).
The larvae of genus Sterictiphora feed on cherry and serviceberry (Smith, 1979). The adults of genus Sterictiphora are easily distinguished from the other genera of Sterictiphorinae by following characters: convex anterior margin of the head in dorsal view, hind wing with very long anal cell.
As a result of this study, we report five new species, Sterictiphora rugosa sp. nov., S. gapjangensis sp. nov., S. flavicollis sp. nov., S. koreana sp. nov. and S. daeguensis sp. nov. and provide a key to Korean species and diagnosis with photos of five new species.
