The caridean shrimp genus Thor Kingsley, 1878 (Thoridae) is currently represented by 14 species distributed in shallow tropical to subtropical waters in the Indo-Pacific, East Pacific and West Atlantic oceans. In this study, two species of the genus are reported on the basis of material from Okinawa and Kume islands in the Ryukyu Archipelago, southern Japan. Thor leptochelus (Xu & Li, 2015) n. comb., recently described from Xisha Islands, China and originally assigned to Thinora Bruce, 1997, is transferred to Thor. Relationship of the species to three congeneric species (T. cordelli Wicksten, 1996, T. spinipes Bruce, 1983 and T. spinosus Boone, 1935) is discussed. The second is T. marguitae Bruce, 1973, representing the rediscovery since the original description and new record for Japanese waters. The four specimens of T. leptochelus were all free-living, whereas the single specimen of T. marguitae was found to be associated with a solitary fungiid coral, as previously reported.
铠甲虾属Thor Kingsley，1878年（铠甲虾科）目前有14个物种，分布于印度-太平洋、东太平洋和西大西洋的热带至亚热带浅水区。在本研究中，基于来自日本南部琉球群岛冲绳岛和久米岛的材料，报道了该属的两个物种。细螯铠甲虾（Thor leptochelus）（Xu & Li，2015年）新组合，最近在中国西沙群岛被描述，最初被归入Thinora Bruce，1997年，现被转移到Thor属。讨论了该物种与三个同属物种（科氏铠甲虾（T. cordelli）Wicksten，1996年；刺足铠甲虾（T. spinipes）Bruce，1983年；多刺铠甲虾（T. spinosus）Boone，1935年）的关系。第二个物种是玛氏铠甲虾（T. marguitae）Bruce，1973年，这是自最初描述以来的重新发现，也是日本海域的新记录。细螯铠甲虾的四个标本都是自由生活的，而玛氏铠甲虾的单个标本如先前报道的那样，被发现与一种独居的石芝珊瑚有关。
