Remarks.
This species closely resembles M. maculatus (Iwamoto, 1943) by the noduli laterals at almost the same distance from the lateral margins, and the morphology of pleopod 1 exopod. However, it can be distinguished in having the eyes with 20–24 ommatidia, male pereopod 6 fringed with long setae and bearing a distal protrusion on the sternal margin at the basis, and the ischium of pereopod 7 fringed with setae as well. In M. maculatus, its eyes have 15 or 16 ommatidia, the basis of pereopod 6 and the ischium of male pereopod 7 with sparse setae. For detailed descriptions and illustrations of M. koreanus see Kwon (1993).

China (Anhui, Chongqing, Guangxi, Guizhou, Hubei, Hunan, Jiangsu, Jiangxi, Shaanxi, Sichuan, Yunnan, Zhejiang), Japan, and Korea.
