Figures: 1E–F, 2C–D, 3E, 5C–G

Plagiognathus miyamotoi Kerzhner 1988b: 64 (n. sp.)

Europiella miyamotoi: Schuh et al., 1995: 391 (n. comb.); Schuh, 1995: 316 (cat.); Kerzhner and Josifov, 1999: 346 (cat.); Yasunaga, 2001b: 164 (diag., fig.).

Diagnosis. Generally recognized by large body; usually pale yellow coloration; pale entire antennae and legs; antennal segment II nearly equal to width of pronotum; short labium reaching apex of mesocoxa; scattered spots ventrally on distal half of metafemora ( Fig. 3 E), and dorsally at subapical region with few minute spots; length of metafemora nearly equal to length of pronotum.

Male genitalia ( Fig. 5 C–F). Endosoma: Shape S–like, with two broad and sub–equal apical processes; from the basal curving area, a chitinised slender leafy structure arising as in figure 5C. Phallotheca: As in figure 5E. Left paramere: Body large, structure as in figure 5F. Right paramere: As in figure 5D.

Female genitalia ( Fig. 3 G). Bursa copulatrix with semi sclerotized plates, and sclerotized rings asymmetrical, elongated oval.

Measurements. (1♀). Body length 4.53; head width across eyes 0.87; vertex width 0.45; lengths of antennal segments I–IV: 0.33, 1.38, 0.95, 0.69; total length of labium 1.45; mesal pronotal length 0.74; basal pronotal width 1.33; width across hemelytron 1.82; and lengths of metafemur, tibia and tarsus: 1.86, 2.52, 0.62.

Specimens examined. South Korea: Gyeongsangbuk–do: 1♀, Uiseong-gun, 24.v.2000, on Boehmeria nivea (L.) Gaudich ( Urticaceae ), S.H. Lee. Japan: Hokkaido: 1♂, Etanbetsu, Asahikawa C., 18.vii.1998, T. and M. Yasunaga, det. by T. Yasunaga, 2008; 1♀ and 5th instar, same data as above, 4.vii.1998, on Aster glehni Fr. Schm., T. Yasunaga ; 1♀, Aoyama, T. Tobetsu, 2.viii.1997, R. Endoh, det. by T. Yasunaga, 2008.

Distribution. Japan, Korea *, Russia.

Host. Artemisia gigantea Kitamura ( Kerzhner, 1988b) ; Aster glehni Fr. Schm. (Asteraceae) . Remarks. Only one specimen was observed and was confirmed after comparing it with reference specimens (Japanese specimens from Yasunaga). The label data showed it was collected on Boehmeria nivea (L.) Gaudich (Utricaceae), but the breeding host is unknown in Korea.
