New species of the genus Spio (Annelida, Spionidae) from the southern and western coasts of Korea

A new spionid polychaete, Spio pigmentata sp. nov., is described from the southern and western coasts of Korea. This new species differs from its congeners by the combination of the following morphological characteristics: the presence of orange-brown pigmentation on the anterior part of the prostom...
