摘要

: Kamaka corophina Ren & Sha, 2013(甲壳纲:Amphipoda: Kamakidae)在日本西南部琉球群岛采集的个体。这是在日本首次发现的片足类动物，也是在日本发现的该属的第五种。Kamaka corophina的特征是雄性触角2的叶柄4肿胀，在后远端角处有一个小突起，雄性颚足目2的似足部有一个斜掌或横向掌，而每只纲5-7的基部有5-9个后羽状刚毛。中国原始冠棘雄颌足目2只有一个斜掌，而日本标本中的雄颌足目2有两种掌。

First record of Kamaka corophina Ren & Sha, 2013 (Crustacea: Amphipoda: Kamakidae) in Japan

: Kamaka corophina Ren & Sha, 2013 (Crustacea: Amphipoda: Kamakidae) individuals were collected from the Ryukyu Archipelago in Southwest Japan. This is the ﬁrst record of the amphipod in Japan and the ﬁfth species of the genus in Japan. Kamaka corophina is characterized by a swollen peduncular article 4 of the male antenna 2 with a small process at the posterodistal corner, the male gnathopod 2 propodus with an oblique or transverse palm, and the bases of pereopods 5–7 each bearing 5–9 posterior plumose setae. Although the male gnathopod 2 in the original K. corophina from China has only an oblique palm, those in the Japanese specimens have two types of palm.
