Specimens examined. South Korea: Gangwon–do: 5♀, Honcheon–gun, Sambong Natural forest, 25.vi.2003, on light trap, J.W. Seong. Jeollanam–do: 1♀, Jangseong–gun, on light trap, R.K. Duwal. Gyeongsangnam–do: 1♀, Goeje–si, Irun–myeon, Jisimdo, 28–29.viii.2008, R.K. Duwal and S. Jung.

Distribution. Korea, Russia.

Host. Radbosia excisa (Maxim.) H. Hara (Lamiaceae) [Kerzhner, 1988a, Schuh et al., 1995]. Remarks. Europiella gilva is recognized from only a few female specimens from light traps; therefore, its biology is unknown in Korea.
