Figs 4 , 17–18 ; Map 7 .

Lesteva nipponica Watanabe, 1990: 164 (type locality: Japan, Honshu, Nara Prefecture, Mt. Kasuga-yama)

MATERIAL. 1 ♂: Stolbovskoy Stream above springs, 21.07.2013, K.V. Makarov leg. ( CS) .

DISTRIBUTION. Russia: southern Kurile Islands (Kunashir: Map 7 ). — Japan (Honshu).

BIONOMICS. The specimen was collected on a steep slope on the bank of a cold stream near thermal springs.

REMARKS. Habitus as in Fig. 4 . In the present study we provide more detailed figures of the aedeagus ( Figs 17–18 ), since Figs 195–197 in Watanabe [1990] are somewhat sketchy. This species is recorded from Russia and Kunashir for the first time.
