项目摘要

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.

对西南诸岛（吐罗诸岛、冲绳、八重山诸岛）进行了考察，收集了大量蜘蛛，对保存在国立科学博物馆的管巢蛛科蜘蛛标本进行了分类学和形态学研究。本标本是在日本北海道、东北和北陆地区，以及泰国、马来西亚、台湾和马达加斯加等地采集的，记述了池袋管巢蛛Clubionaikedai、熊岛管巢蛛C.kumadaorum和山岛管巢蛛C.mayamiae新种，另外3种管巢蛛Clubionakasanensis、普通管巢蛛C.trivialis和东北管巢蛛C.mandschurica，对台湾管巢蛛科蜘蛛进行了深入研究，共鉴定出14种，其中包括4新种。其中7种也来自日本，特别是台湾区系与八重山群岛区系的关系密切，以皮质管巢蛛（Clubionacorticalis）的种群占优势。日本管巢蛛属蜘蛛被分为15个种群，约60种。根据这些蜘蛛的物种形成和观察，可以有把握地说，日本的管巢蜘蛛区系丰富，并由许多不同的因素组成。但与欧亚大陆，特别是西伯利亚、中国和朝鲜的动物区系关系密切。
