Remarques
Estuaries. After Soh & al. (2012, p.238) this species is very closely related to P. inopinus and P. nansei. It is a dominant species in salinity between 5 and 15, in estuarine waters of southeastern Korea in spring and autumn, while P. inopinus is restricted to western estuarine waters of Korea occurring at salinities < 30 with P. popesia. However, Chang (2009) showed that P. inopinus occurs widely in the inland waters of Korea.
After genetic analysis, Sakaguchi & Ueda (2018) show that P. koreaanus from Korea belonged to the same clade as the P. japonicus Kikuchi, 1928, and becomes a junior synonym.
