Abstract
The Careproctus rastrinus species complex, widely known from the North Pacific, has been revealed recently to include nine genetically divergent groups on the basis of mitochondrial DNA (mtDNA) sequence variations. Herein we describe an AFLP analysis that focuses on three closely related groups in order to clarify the evolutionary history of the species complex in the Sea of Japan and off the Pacific coast of Japan. A principal coordinate analysis indicated the absence of nuclear divergence in two groups defined by mtDNA variations in the Sea of Japan, whereas another group from the Pacific coast of northern Japan was clearly distinct. This suggests extensive gene flow between two groups in the Sea of Japan as a result of secondary contact.
