Abstract
A new hermit crab species of Paguridae, Trichopagurus spinibrachium n. sp., is described on the basis of a single male specimen collected from the anchialine environment of a semi-submerged marine cave in Okinawa Island, Ryukyu Islands, southwestern Japan. It is morphologically similar to T. macrochela Komai & Osawa, 2005 and T. tenuidactylus Komai, 2013, but differs in the shape and armature of the ocular, antennular and antennal peduncles, chelipeds, and ambulatory legs. The new species may be distinguished from all known congeners by the stronger armature of the carpi and meri of both chelipeds. Trichopagurus spinibrachium n. sp. is the third species of the genus recorded from submarine caves, although it may also occur on nearby coral reefs as does T. macrochela and T. trichophthalmus (Forest, 1954).
A new species of the genus Trichopagurus de Saint Laurent, 1968 (Crustacea: Decapoda: Anomura: Paguridae) from a semi-submerged marine cave in Okinawa Island, southwest Japan.
根据从日本西南部琉球群岛冲绳岛的一个半潜海洋洞穴的锚系环境中采集到的一个雄性标本，描述了寄居蟹科的一个新物种--Trichopagurus spinibrachium n. sp.。在形态上，它与 T. macrochela Komai & Osawa, 2005 和 T. tenuidactylus Komai, 2013 相似，但在眼睛、触角和触角柄、螯足和伏足的形状和纟上有所不同。新种与所有已知同属种的区别在于两螯足的腕部和腓部具有更强的纟。Trichopagurus spinibrachium n. sp.是该属在海底洞穴中记录的第三个物种，尽管它也可能像 T. macrochela 和 T. trichophthalmus 一样出现在附近的珊瑚礁中（Forest，1954 年）。
期刊介绍：
Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
