Three species of the pagurid hermit crab genus Catapaguroides A. Milne-Edwards & Bouvier, 1892, all from Japanese waters, are reported. Catapaguroides fragilis (Melin, 1939) is redescribed on the basis of the holotype and additional material from southern Japan. Diagnostic characters of this poorly known species are fully assessed. Two new species, C. bythos and C. rubromaculatus, are described and illustrated on the basis of material from upper bathyal depths off the Ryukyu Islands. Catapaguroides rubromaculatus n. sp. resembles C. fragilis and C. hirsutus Komai & Rahayu, 2013, but the characteristic shape of the ocular peduncle and the elongate male right sexual tube with an anteriorly directed distal portion readily separate C. rubromaculatus n. sp. from the latter two congeners. Catapaguroides bythos n. sp. appears close to C. mortenseni de Saint Laurent, 1968 and C. pectinipes (Lewinsohn, 1969), but the different armature of the chelipeds distinguishes C. bythos n. sp. from the latter two allies. Catapaguroides is now represented by 30 species.
报道了采自日本海域的3种Pagurid寄居蟹属Catapaguroides A.米尔恩 - 爱德华兹和布维耶,1892年,均来自日本海域。脆弱卡特帕古陆寄居蟹(Melin,1939年)基于正模标本和来自日本南部的补充材料进行了重新描述。对这个鲜为人知的物种的诊断特征进行了全面评估。根据琉球群岛深海区域的材料描述并图示了两个新物种,即深海卡特帕古陆寄居蟹和红斑卡特帕古陆寄居蟹。红斑卡特帕古陆寄居蟹新种与脆弱卡特帕古陆寄居蟹和多毛卡特帕古陆寄居蟹(小间和拉哈尤,2013年)相似,但眼柄的特征形状以及雄性右性管细长且远端向前的部分使红斑卡特帕古陆寄居蟹新种易于与后两个同属物种区分开来。深海卡特帕古陆寄居蟹新种似乎与莫滕森卡特帕古陆寄居蟹(德圣洛朗,1968年)和栉足卡特帕古陆寄居蟹(莱温松,1969年)相近,但螯足的不同刚毛结构将深海卡特帕古陆寄居蟹新种与后两个近缘物种区分开来。卡特帕古陆寄居蟹属目前有30个物种。
