Characteristics and the origin of East Asian spiders, based on a view of species diversity and phylogeny of liphistiids

1)由生活在日本和东亚国家森林保护区的原始陷阱蜘蛛组成的Liphistiidae科被认为是蜘蛛研究中最重要的类群之一。在日本九州和琉球群岛的森林中进行了调查访问，并在这些领域获得了良好的收集蜘蛛及其生态学数据。2）所获得的标本进行了形态学和分类学研究，并与来自亚洲国家的物种标本进行了比较，如越南，泰国和马来西亚。3）在日本蜘蛛学学会和国际蜘蛛学学会的大会上作了口头报告，并与欧美蜘蛛学家进行了讨论。论文发表在国际学会的科学期刊上4）在系统研究已知种和越南发现的两个新种的基础上，将分布于日本、中国和越南的七针蛛亚科分为Ryuthela、Heptathela、Abcathela、Songthela和Vinathela五个类群，并讨论了它们之间的亲缘关系（Ono，1999，Journal of Arachnology）。5）通过对日本琉球群岛和九州的实地调查，确认了日本的天蛾科2属16种。2001年在萨尔斯堡举行的德国和国际蛛形纲学会议上讨论了它们的动物地理学、生物学特征和地质历史。

1) The family Liphistiidae composed of primitive trap door spiders living in the preserved forests in Japan and East Asian countries is regarded as one of the most important groups in the study of spiders. Research trips were conducted in forests of Kyushu and the Ryukyu Islands, Japan, and a good collection of the spiders as well as their ecological data were obtained in those fields.2) Obtained specimens were morphologically and taxonomically studied, and compared with specimens of species of the family collected from Asian countries as Vietnam, Thailand and Malaysia, which were deposited in the collection of the National Science Museum Tokyo and some European museums.3) Results of the study were orally presented at congresses of the Arachnological Society of Japan and the International Society of Arachnology and discussed with European and American arachnologists. Papers were published in the scientific journals of international societies (see following references).4) The subfamily Heptathelinae distributed from Japan, China and Vietnam were divided into five groups, Ryuthela, Heptathela, Abcathela, Songthela and Vinathela, on the basis of systematic study of known species and two new species found in Vietnam, and their relationships were discussed (Ono, 1999, Journal of Arachnology).5) Sixteen species of two heptatheline genera of the family Liphistiidae were recognized in Japan through field investigations in the Ryukyu Islands and Kyushu. Their zoogeographic and biological characteristics as well as geological history were discussed and presented at the congress of German and International Meeting of Arachnology at Salzburg, 2001.
