DISTRIBUTION. Russia: Maritime Province, southern Kurile Islands (Kunashir: Map 8 ). — Japan (Honshu, Shikoku, Kyushu). The record of L. plagiata for South Korea by Cho et al. [2002] is a misidentification of L. miyabi Watanabe, 1990 [ Kim, Ahn, 2011].

BIONOMICS. Specimens were collected on stone banks of streams and rivers ( Figs 13, 15 ).

REMARKS. In the original description [ Sharp, 1889], the number of syntypes was not specified. The first author designates a lectotype to fix the identity of the name. Lesteva plagiata is a relatively variable species both in habitus and in the shape of the apical portions of the aedeagus and parameres. It is similar to L. kojohamana Watanabe, 1990 , described from Iburi, Hokkaido, and a potential synonym of L. plagiata . A revision of type material would be required to confirm this. Habitus as in Fig. 5 . The aedeagus of L. plagiata in two projections is illustrated in Figs 19–20 . The species is recorded from Kunashir Island for the first time.
