The Asian shrimp Palaemon macrodactylus is native to the north-western Pacific Ocean. After introduction in the USA it has spread rapidly. The species has recently been found in two distant regions along the European Atlantic coasts: south-western Spain and the southern North Sea. In the present paper the first records of the species in the southern bight of the North Sea are presented and discussed. The morphology and colour pattern of P. macrodactylus is described and illustrated, based on European specimens. A detailed identification key to the Palaemonidae of northwestern Europe, southwards down to the Bay of Biscay, is given. In the field, adult and subadult specimens of P. macrodactylus can be readily identified by the presence of a whitish longitudinal dorsal stripe running all along their back.
