The Korean record of Scolytoplatypus mikado Blandford 1893 is originated from Murayama (1929) whereas Wood(1989) synonimyzed S. sinensis Tsai & Huang 1965 as a junior synonym of S. mikado Blandford 1893. In 2010, the authors collected several specimens from Korea and Japan and found considerable morphological differences between S. sinensis and S. mikad the process on the prosternum, the pubescences on the procoxae, and the shape of the male elytral declivity. Comparing the Cytochrome Oxidase I and 16S rRNA gene, we also found the genetical gap between the South Korean specimens (= S. sinensis, with the Japanese sample from Mt. Tsukubasan) and the sample from Mt. Yamizosan, Japan (= S. mikado). Accordingly, S. sinensis Tsai & Huang 1965 is here reinstated.
