A new species of pagurid hermit crab, Pagurus decimbranchiae, is described and illustrated based on 20 specimens collected from shallow waters of the Pacific coast of Japan ranging from Boso Peninsula to Tanegashima Island. It is quite distinctive in having the rudimentary arthrobranch on the third maxilliped represented by a single bud, however close morphological similarity is found between the new species and P. moluccensis Haig and Ball. Comparisons are also made among other species, including P. boriaustraliensis Morgan, P. sp. cf. boriaustraliensis sensu Rahayu and Komai (2000) and the members of the P. anachoretus group. The present generic assignment of the new species should be considered provisional, as more extensive study is needed to investigate phylogenetic relationships of the new species and the other species of Pagurus.
基于从日本太平洋沿岸浅水区（从房总半岛到种子岛）采集的20个标本，描述并图示了一种新的寄居蟹物种——十指鳃寄居蟹（Pagurus decimbranchiae）。它非常独特，第三颚足上的鳃肢退化，仅由一个芽体代表，然而，在新物种与莫鲁克鳃寄居蟹（Pagurus moluccensis Haig and Ball）之间发现了密切的形态相似性。还对其他物种进行了比较，包括澳大利亚鳃寄居蟹（Pagurus boriaustraliensis Morgan）、疑似澳大利亚鳃寄居蟹（Pagurus sp. cf. boriaustraliensis sensu Rahayu and Komai，2000）以及隐居鳃寄居蟹（Pagurus anachoretus）组的成员。由于需要更广泛的研究来调查新物种与其他鳃寄居蟹物种的系统发育关系，因此新物种目前的属级分类应被视为临时的。
