Distribution. Asia: [ Azerbaijan, China, Japan, Kazakhstan, Korea *, Russia, Uzbekistan], North America, and European continents.

Host. Artemisia absinthium L. and A. vulgaris L. ( Asteraceae ) [Wagner, 1975].

Remarks. Europiella artemisiae is the most common species of the genus occurring in Korea, feeding on Artemisia , and abundantly emerging from early spring to late autumn. The formerly reported species from Korea ( Kwon et al., 2001), Europiella albipennis is considered a misidentification of E. artemisiae , because all the collected materials during our survey from 2008–2011, and the North Korean materials (collections of Josifov) which were observed in this study, were identified as E. artemisiae rather than E. albipennis . Therefore, we confirm E. artemisiae occurs in Korea; and E. albipennis is removed from the Korean list.
