Abstract

According to conventional views, the rosy bitterling, Rhodeus ocellatus, comprises two subspecies, R. ocellatus kurumeus and R. ocellatus ocellatus, the former being native to Japan whereas the latter was introduced into Japan from China during World War II. To examine the genetic structure of Japanese R. ocellatus, part of the mitochondrial cytochrome b gene from 48 individuals collected from various locations in Japan was sequenced. Three major mitochondrial lineages were found. Based on historical evidence, two of these represent R. ocellatus ocellatus and the third R. ocellatus kurumeus. The existence of two distinct lineages of R. ocellatus ocellatus in Japan suggests at least two colonizations. Some local populations comprised purely R. ocellatus kurumeus, but those from Kashima and Ogori included both subspecies. Because the proportion of R. ocellatus ocellatus in Kashima increased from 1994 to 1995, invasion by R. ocellatus ocellatus into R. ocellatus kurumeus habitats is apparently in progress.
