Figures: 1B, 3B, 5A

Plagiognathus gilvus: Kulik, 1965: 155 (n. sp., desc., figs.); Kerzhner, 1979: 54 (desc., figs.); 1988a: 855 (key)

Europiella gilva: Schuh et al., 1995: 390 (n. com.); Kerzhner and Josifov, 1999: 345 (cat.); Kwon et al., 2001: 171 (cat.).

Diagnosis. Generally recognized by medium–sized, elongated oval body; entirely pale greenish coloration; pale dorsum with dark areas underneath apex of cuneus; ventrally densely distributed spots at distal region of metafemora arranged in two rows towards the base ( Fig. 3 B).

Male genitalia. For figure and description of male genitalia, see Kerzhner, 1979: 51 (as Plagiognathus gilvus ).

Female genitalia ( Fig. 5 A). Bursa copulatrix with semi–sclerotized areas on posterior regions beneath the sclerotized rings, sclerotized rings somewhat oval, broad and thin–rimmed.

Measurements. (5♀). Body length 3.55–3.86; head width across eyes 0.77–0.83; vertex width 0.38–0.48; lengths of antennal segments I–IV: 0.22–0.28, 0.92–0.97, 0.52–0.62, 0.34–0.41; total length of labium 1.40–1.49; mesal pronotal length 0.57–0.65; basal pronotal width 1.26–1.40; width across hemelytron 1.63–1.74; and lengths of metafemur, tibia and tarsus: 1.22–1.32, 1.86–1.99, 0.42–0.51.

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.
