Abstract

A slipper lobster species Chelarctus virgosus recently separated from C. cultrifer (Ortmann 1897) by Yang and Chan (2012) was caught by a baited trap at a depth of 30 m, from off Onagawa, Oshika Peninsula (southern end of the Sanriku Coast), northeastern Japan. This record verified the distribution of C. virgosus in Japan. Also, this is the first record of scyllarid lobsters from the coastal waters of the Kuroshio-Oyashio Mixing Zone, updating the northern limit of distribution by more than 300 km. In addition, possible Japanese records tentatively listed in the original description of C. virgosus are revisited, and the distribution on the Pacific coast at the Boso Peninsula to the Ryukyu Archipelago was confirmed.

日本东北部大鹿半岛的 Chelarctus virgosus Yang 和 Chan 的首次记录（甲壳类、十足目、青蟹科），2012 年：拖鞋龙虾向北延伸 300 公里

摘要

Yang 和 Chan (2012)最近从C. cultrifer (Ortmann 1897 ) 中分离出一只拖鞋龙虾物种Chelarctus virgosus，在大鹿半岛女川 (三陆海岸南端) 附近 30 m 深处用诱饵捕获。 ，日本东北部。该记录证实了C. virgosus在日本的分布。此外，这是黑潮-亲潮混合带沿岸水域首次记录青龙虾，将分布范围北部界限更新了300多公里。此外，重新审视了C. virgosus原始描述中暂定的日本可能记录，并确认了房总半岛太平洋沿岸至琉球群岛的分布。
