DISTRIBUTION: Russia (Far East) and Korea (middle part; new record).

MATERIAL EXAMINED: 1 female, 22.vii.2007, on Taxus cuspidata S. et Z. ( Taxaceae ), Hongcheon-eup, Hongcheongun, Gangwon-do, South Korea, leg. J. Seong.

DISCUSSION AND BIOLOGICAL NOTES. A single specimen of the species was collected on the bark of a live tree, Taxus cuspidata (Taxaceae) ( Fig. 1 a) with unidentified coccids. Therefore, we assumed this species fed on those coccids. The single specimen quickly responded to the presence of the collector by jumping along the trunk and branches of the tree rather than walking.
