REMARKS. Bey-Bienko (1951) described this species from the southern part the Russian

Far East (Ussuriysk and Zareche settlement at 16 km SW Posyet) and NE China. He noted some strong relationships of this taxon and the tropical members of this genus. Later BeyBienko (1954) mentioned the locality of the species in N Korea.

DISTRIBUTION. Russia: Khabarovsky krai (new record), Primorsky krai (SW and along the Ussuri River valley); NW, N, NE, E, SW China, Korea (Jin & Xia, 1994; Storozhenko et al., 2015).

ECOLOGY. Our data show that the species prefers shrubs (especially Lespedeza bicolor )

on openings and along edges of deciduous forests and meadows with tall vegetation as well

(cf. Stebaev et al., 1989). In shrubs, its abundance may be about 1.5–8 ind./hour (with average density between 0.02 and 0.11 ind./m 2). It is relatively rare over meadow vegetation.

Importantly, our recent observations showed that the species can settle some transformed habitats as well.
