Review of the Asian wood-boring genus Euxiphydria (Hymenoptera, Symphyta, Xiphydriidae)

Abstract

Five species of Euxiphydria are recognized, E. leucopoda Takeuchi, 1938, from Japan, E. potanini (Jakovlev, 1891) from Japan, Russia, Korea, and China, E. pseudoruficeps Okutani, 1966, from Taiwan, E. vietnamensis, sp. n. from Vietnam, and E. shaanxiana, sp. n., from China. Euxiphydria subtrifida Maa, 1944, is considered a new synonym of E. potanini. A key and illustrations are given to distinguish the species.
