抄録

Seventeen juvenile specimens of the tropical ghost crab Ocypode sinensis Dai, Song & Yang, 1985 (Ocypodidae) were found on three sandy beaches in Shinonsen-cho, Hyogo Prefecture, western Honshu, Japan. This represents the first record of the species from the coast of Sea of Japan. These juveniles of O. sinensis occurred around shorelines of the sandy beaches, together with juveniles of temperate O. stimpsoni. Their co-occurrences suggest that, at least the juveniles of tropical O. sinensis and native temperate O. stimpsoni may compete for the habitat. The range extension of the tropical O. sinensis, especially towards the north along the coast of the Sea of Japan, should be monitored in the context of possible competitions with native species.
