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.
