Rostrum yellowish brown, reaching apex of middle coxa; apical part of segment IV dark. Pronotum entirely pilose except basal margin, yellowish brown or orange on posterior lobe, sometimes with a longitudinal stripe along with middle of pronotum (see remarks), calli dark grayish brown, pruinose, with sparse, silky pubescence; mesoscutum and scutellum dark grayish brown, shagreened, somewhat arched, transversely rugose; pleura widely grayish brown, pruinose, except for propleuron shiny dark brown. Hemelytra dark brown, weakly shagreened; anterolateral part of corium and base and apex of cuneus widely yellow; embolium yellow; membrane dark grayish brown, with a pale spot along apex of cuneus.

Dimensions (in mm). Female: Body length 5.89–6.23; head width including eyes 0.98–1.04; vertex width 0.45–0.48; rostral length 1.25–1.47; mesial pronotal length 0.79–0.95; basal pronotal width 1.35–1.39; width across hemelytra 1.48–1.14.

Distribution. Russia (Fareast), Korea (Whole).

Biology. The species is confirmed to feed on the leaves of Quercus aliena during laboratory observations. The species is sometimes attracted to light traps in May in Korea.

Remarks. The specimens from South Korea show a light orange color pattern on the entire pronotum, whereas the ones from the Fareast Russia and North Korea show a dark orange color pattern on the entire pronotum, and a brownish longitudinal stripe on the posterior lobe of the pronotum.
