Distribution.

Russia (Far East: Primorsky Krai) ( Kerzhner 1988 b), South Korea ( Gyeonggi-do, Gangwon-do, Gyeongsangnam-do, Jeollabuk-do) ( Ahn et al. 2018).

Note.

This species is widely distributed in South Korea, where it inhabits the bark of multiple deciduous tree species (Table 3 View Table 3 ). Kerzhner (1988 b) briefly mentioned three nymphs that might pertain to this species collected from Ryazanovka, Primorsky Krai, on the bark of Quercus sp. ( Fagaceae ) and Ulmus sp. ( Ulmaceae ), but no additional information is available. We present images of the final-instar nymphs for the first time (Fig. 6 F View Figure 6 ); at first glance, it resembles I. hananoi Hasegawa, 1946 from temperate Japan in having a dark dorsum scattered with small, whitish spots ( Tsunoda et al. 2020), but they can be distinguished by the spots being smaller and sparser, and the dark brown tergal segments with a medial bright region, its width approximately 1 / 4 of each abdominal segment.

Kerzhner (1988 b) reported individuals collected at light in two localities from Primorsky Krai. Similarly, we collected eight females at a light trap in Sancheong-gun, Gyeongsangnam-do Province. Additionally, a single male was collected at light in Mt. Maisan, Jeollabuk-do Province (WG Kim, pers. comm.).
