| Research Abstract |
Family Liparidae is one of the specious taxa in the North Pacific. In this study, the diversity and evolutionary history of the family were explored on the basis of molecular and morphological analyses. A new species, Careproctus notosaikaiensis, was described from the Sea of Japan, which is one of the semi-enclosed seas in the North Pacific. Also, a new species closely related with Careproctus colletti is to be described from the Sea of Japan. The genetic and morphological divergences were found among the local populations (e.g., Sea of Japan, Sea of Okhotsk, Bering Sea, Pacific Ocean) of the Careproctus rastrinus and Crystallychthys matsushimae, suggesting they may include some cryptic species. Because the species of Liparidae usually lay large demersal eggs, they may easily differentiate among local population, resulting their diversity.
