Abstract

A new species of Takedactylus Naruse & Maenosono, 2012, and a new genus and species of Aphanodactylidae are described from Japan. Takedactylus compressus n. sp. is collected from Ogasawara Islands. This new species is distinct from the only congener, Takedactylus masatsunei, by the shapes of the carapace, third maxilliped and the ambulatory legs. Another new species, monotypic Lichtylus kaisha n. gen., n. sp., is distinct from all other aphanodactylid species, in generic level, in the shape and position of the palp of third maxilliped, relatively long and slender ambulatory legs, and a combination of other important characters, i.e. the contour of the carapace, the degree of gap between third maxillipeds, condition of the distoflexor corners of second to fifth ambulatory propodi, and relative length of ambulatory dactyli. The present study brings the number of aphanodactylid taxa to 7 genera and 15 species. http://zoobank.org/urn:lsid:zoobank.org:pub:0B01E38B-A542-4D22-966F-43B01E8D57D5 http://zoobank.org/urn:lsid:zoobank.org:act:C1EAADE1-1774-4EED-B62D-8EB2BFDC1C32 http://zoobank.org/urn:lsid:zoobank.org:act:195D7820-DB42-4BD6-AF66-F8C91A42B3FE http://zoobank.org/urn:lsid:zoobank.org:act:8A2C77F2-184D-4D7F-9317-03D6C8FC8D0D

日本琉球和小笠原群岛的无齿目两新种（甲壳纲：十足目：Brachyuna），并建立了一个新属

记述了日本竹竹属(Takedactylus Naruse & Maenosono, 2012)一新种和竹竹科(Aphanodactylidae)一新属和新种。小笠原群岛采自竹竹(Takedactylus compressus)。这个新种不同于唯一的同类——竹爪龙(Takedactylus masatsunei)，它们的甲壳形状、第三上唇和活动腿都不同。另一新种单型Lichtylus kaisha n. gen.， n. sp.在属级、第三上肢触须的形状和位置、相对修长的活动腿以及甲壳轮廓、第三上肢之间的间隙程度、第二至第五活动肢的远伸角的状况和活动趾的相对长度等重要特征的组合上都与其他所有无肢动物不同。目前，无手虫分类群已达7属15种。http://zoobank.org/urn:lsid:zoobank.org:pub:0B01E38B-A542-4D22-966F-43B01E8D57D5 http://zoobank.org/urn:lsid:zoobank.org:act:C1EAADE1-1774-4EED-B62D-8EB2BFDC1C32 http://zoobank.org/urn:lsid:zoobank.org:act:195D7820-DB42-4BD6-AF66-F8C91A42B3FE http://zoobank.org/urn:lsid:zoobank.org:act:8A2C77F2-184D-4D7F-9317-03D6C8FC8D0D

期刊介绍： Tropical Zoology is an international zoological journal publishing original papers in the field of systematics, biogeography, phylogeny, ecology and conservation of all terrestrial and aquatic animal Phyla from tropical and subtropical areas. Only papers with new information, high quality and broad interest are considered. Single species description and checklists are not normally accepted. Review papers are welcome. The journal is owned by the Istituto di Ricerca sugli Ecosistemi Terrestri of the Consiglio Nazionale delle Ricerche, Florence, Italy (CNR-IRET) who performs research into the structure and functioning of aquatic and terrestrial ecosystems, focusing in particular on anthropogenic pressure and global change. The knowledge amassed forms the scientific basis for identifying the most appropriate protective and corrective interventions, and provides support for the bodies entrusted with formulating policies for environmental protection and recovery.
