Europiella Reuter, 1909

Europiella Reuter, 1909: 83 (n. gen.); Schuh et al., 1995: 379 (n. syn., disc.); Schuh, 1995: 312 (cat.); 2004: 2 (diag., desc.); Kerzhner and Josifov, 1999: 343 (cat.); Yasunaga, 2001: 162 (diag.); Kwon et al., 2001: 170 (cat.); Duwal et al., 2010: 21 (diag.).

Type species: Agalliastes stigmosus Uhler, 1893; subsequent designation.

Diagnosis. Recognized by small to medium sized, oval or elongated oval body; completely pale, or greenish, or entirely fuscous or black coloration; reclining simple dark and sericeous setae on dorsum; distribution of spots on metafemora and tibia. For detailed description see Schuh et al., 1995; and Schuh, 2004.

Male genitalia. Pygophore relatively larger than total abdomen. Body of endosoma partially or completely twisted mesally; apex with two apical processes, and occasionally semi–sclerotized or membranous blades arising from basal curved area; and secondary gonopore placed around chitinized bands of endosoma.

Female genitalia: Bursa copulatrix semitransparent with or without minute spinules; sclerotized rings asymmetrical, thin rimmed, and variously shaped.

Remarks. The breeding host for this genus is confirmed as Artemisia spp.; the genus is occasionally also observed on other plants belonging to family Asteraceae, and Lamiaceae in the Palearctic region (Schuh, 2004). In Korea these tiny bugs were mostly collected from asteraceous plants.

The survey confirmed that Eurpiella artemisiae and E. kiritshenkoi are commonly distributed in Korea whereas the remaining species are rare and represented with very few specimens in our collection.
