한국산 Paradoxostoma 속의 분류학적 연구

Abstract

Four species of the genus Paradoxostoma Fischer, 1855 are reported from Korea. Paradoxostoma cf. flaccidum Schornikov, 1975, P. cf. brunneum Schornikov, 1974 and two potentially new species, P. sp. 1 and P. sp. 2. Before this study, six species of the genus Paradoxostoma were recorded from East Sea of Korea including P. flaccidum Schornikov but only as a part of species list without any other details. Paradoxostoma sp. 1 and Paradoxostoma sp. 2 are closely related with P. affine Okubo, 1977 and P. depressum Okubo, 1977, respectively. However, they differ in many details of carapace and soft parts morphology. Here I provide detail description of four Korean species of the genus Paradoxostoma.
