Studies on the fauna of the easternmost areas of Eurasia on the besis of phylogeny and speciation of clubionid spiders

对西南岛屿（托卡拉群岛、冲绳岛和八山群岛）进行了研究旅行，并收集了大量蜘蛛。对国家科学博物馆收藏的蛛科蜘蛛标本进行了分类学和形态学研究。这些标本不仅来自日本北海道、东北和北陆地区，还来自泰国、马来西亚、台湾和马达加斯加，这些标本是由“文武会国际科学研究计划”资助的科学研究项目收集的。其中，有ikedai Clubiona、kumadaorum C.mayamiae新种，kasanensis c.c rivialis和mandschurica C.mayamiae新种[文献2)、3)、5)和6)]。对台湾的棒蛛进行了深入的研究。它们被鉴定为14种，其中包括4种新种。其中日本有记录的有7种；特别是，台湾与八山群岛的动物群关系密切，以皮质球虫属（Clubiona corticalis）为优势种群。将日本蜘蛛分为15个种群约60种。根据这些蜘蛛的系统发育和物种形成的观察，可以有把握地说，日本的俱乐部蛛动物群是丰富的，是由许多不同的因素组成的。然而，其动物群与欧亚大陆，特别是西伯利亚、中国和朝鲜的动物群密切相关。

Research trips to the southwestern islands (the Tokara Islands, Okinawa Island and the Yaeyama Islands) were conducted, and a good collection of the spiders was made.Specimens of the spiders of the family Clubionidae deposited in the National Science Museum were taxonomically and morphologically studied. The specimens were collected not only from Hokkaido, Tohoku and Hokuriku Districts in Japan but from Thailand, Malaysia, Taiwan and Madagascar by the scientific researches supported by the Grants-in-aid for Field Research of the Monbusho International Scientific Research Program.There new species, Clubiona ikedai, C.kumadaorum and C.mayamiae, were described and another three species, Clubiona kasanensis, C.trivialis and C.mandschurica, were newly recorded from Japan [references2), 3), 5) and6)].Clubionid spiders from Taiwan were intensively studied.They were identified into 14 species including 4 new ones. Of these, 7 species were recorded also from Japan ; particularly, a close relationship between the fauna of Taiwan and that of the Yaeyama Islands was recognized in dominance of the species-group of Clubiona corticalis.Japanese spiders of the genus Clubiona were classified into about 60 species of 15 species-groups. On the basis of the phylogeny and observations of the speciation of these spiders it can be safely said that the fauna of Japan in the clubionid spiders is rich and made by many different factors. However, the fauna is closely related to that of the Eurasian continant, especially of Siberia, China and Korea.
