Material examined. About 40 specimens, including the type series. One specimen is from the Russian Far East (Shinohara 1987a).
Distribution. Russia (Sakhalin), Japan (Hokkaido, Kunashiri Is.) (Sundukov 2015).
Host plant. Rosaceae: Rubus parvifolius L. (Hara & Shinohara 2017).
Remarks. This species is similar to two Japanese species, O. minomalis (Takeuchi, 1930) and O. similis Shinohara, 1987, and a Chinese species, O. atra Shinohara & Wei, 2016 (Shinohara 1987a; Shinohara & Wei 2016). Molecular data are not available for O. atra, but we have COI and NaK sequences for O. minomalis, O. similis and O. yezoensis and they formed a clade with 100% UFBoot support in the COI and 99% UFBoot support in the NaK genes (Figs 139, 153). In the COI analysis, the two sequences of O. yezoensis differed by 0.1% and the nearest neighbour, diverging by a minimum of 2.3%, was O. similis, with which O. yezoensis formed a clade with 100% UFBoot support (Fig. 139). In the NaK analysis, the two sequences of O. yezoensis differed by 0.1% and the nearest neighbour, diverging by a minimum of 0%, was O. similis.
Takeuchi (1936a) first recorded this species as “ Anoplolyda minomalis ” (= O. minomalis) from Sakhalin. Shinohara (1985b), adopting a broader concept of O. minomalis, included Sakhalin in the distribution of O. minomalis. However, Shinohara (1987a) recognized three species in the previous concept of O. minomalis and described the species occurring in Hokkaido and Sakhalin as O. yezoensis, thus excluding Sakhalin from the distribution of O. minomalis. Zhelochovtsev & Zinovjev (1995) correctly understood this history and noted “ yezoensis Shinohara, 1987 (= minomalis auct., in part). — EFE”. Sundukov (2017) included O. minomalis in the Russian fauna, probably according to Shinohara (1985b) and neglecting Shinohara (1987a). Without further evidence, O. minomalis should be excluded from the list of the Russian fauna.
