V. incerta (Takeda & Miyake, 1969), V. typica Ward, 1942, V. quadrispinosa (Zehntner, 1894), and V. longipes (A. Milne-Edwards, 1873), are reported based on specimens collected from the Okinawa Island Group, Central Ryukyus, southern Japan. Notes on their morphological features and taxonomical problems are provided. The specimens identified as V. typica in the present study are distinguished from V. rotumana (Borradaile, 1900) by having tooth-shaped external orbital angle, but the distinguishable characters between the specimens examined and V. woodmasoni (Deb, 1987) remain unclear. In addition, the specimens identified as V. quadrispinosa in the present study can be distinguished from V. xishaensis (Song, 1987) by proportionally narrower male pleon and different dark pattern on the carapace, but the distinguishable characters between the specimens examined and V. nanshensis (Dai, Cai & Yang, 1994) also remain unclear. The taxonomic status and distinguishable characters of these species need to be reconsidered in future studies. Furthermore, “Litocheira quadrispinosa” recorded by Sakai (1976: pl. 191, fig. 3) from the Ryukyu Islands is found to be V. longipes instead, because of strongly converging posterolateral margin of the carapace, strongly protruding front in dorsal view, and different carapace colouration.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"en","subitem_1522300316516":"Ryukyu University Museum, Fujukan"},{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学資料館 (風樹館)"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/47427"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"2187-6657"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"en","subitem_1522650091861":"Fauna Ryukyuana"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2020-12-04","bibliographicIssueDateType":"Issued"},"bibliographicPageEnd":"36","bibliographicPageStart":"15","bibliographicVolumeNumber":"58"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_1522306287251":{"subitem_1522306382014":"URI","subitem_1522306436033":"https://fauna-ryukyuana.webnode.jp/"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"58-2.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2011275/files/58-2.pdf"},"version_id":"3a502b26-4f84-4936-ae10-00e6a19ad3e8"}]},"item_title":"琉球列島産のヒメオキナガニ属 (甲殻亜門: 十脚目: 短尾下目: ケブカガニ科) について","item_type_id":"15","owner":"1","path":["1642838196741","1642838412624"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-12-08"},"publish_date":"2020-12-08","publish_status":"0","recid":"2011275","relation_version_is_last":true,"title":["琉球列島産のヒメオキナガニ属 (甲殻亜門: 十脚目: 短尾下目: ケブカガニ科) について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T06:19:53.303452+00:00"}
