New Record of Two Species of Jassa from Korea (Crustacea: Amphipoda: Ischyroceridae)

During the long-term surveys of marine environment some ischyrocerid amphipods were collected, which indicated the various types of habitats. Among them the two species, Jassa marmarata Holmes, 1903 and J. marinai Conlan, 1990, are here reported from Korea for the first time with short redescriptions. J. marmarata occurs in the cirripedian community, while J. marinai between marine algal colonies at low tide on the rocky shore.
