Abstract

A newly recorded species, Sinocorophium dongtanense, of the genus Sinocorophium was collected from shallow waters of Korea. This species was previously reported as S. homoceratum in Korea. However, after reanalysis of previously studied samples, this species was identified as S. dongtanense, which had previously been reported from the Yangtze estuary, Shanghai, China in 2014. In this study, the newly recorded species is illustrated with a diagnosis and compared to the previously misidentified species. Molecular phylogenetic studies for Sinocorophium species in Korea are provided. A key to the Sinocorophium species in Korea is also provided.
