New Records of the Nereidid Polychaete Leonnates persicus from...

We recorded the nereidid polychaete Leonnates persicus Wesenberg-Lund, 1949 , previously known from coasts of Indian Ocean and western Pacific Ocean, from the coasts of Japan, Korea, and Thailand, based on examination of 27 specimens collected from shallow subtidal or intertidal muddy flats at 16 localities. The morphological characteristics of this material agreed well with those of the holotype from the Persian Gulf. We describe some Important new characteristics of the holotype, which had not been appropriately described in previous literature.
