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保存完好的森林中的原始门蛛组成的门蛛科（Liphistiidae）是蜘蛛研究的重要类群之一。在日本九州和琉球群岛的森林中进行了研究旅行，收集了大量的蜘蛛及其生态数据。2)对获得的标本进行形态学和分类学研究，并与日本东京国立科学博物馆和欧洲一些博物馆收藏的越南、泰国、马来西亚等亚洲国家的该科物种标本进行比较。3)研究结果在日本蜘蛛学会和国际蜘蛛学会大会上口头提出，并与欧美蜘蛛学家进行讨论。论文发表在国际学会的科学期刊上（见以下参考文献）。4)在对越南发现的2个新种和已知种进行系统研究的基础上，将分布于日本、中国和越南的heptathelae亚科划分为Ryuthela、Heptathela、Abcathela、Songthela和Vinathela 5个类群，并讨论了它们之间的关系（Ono, 1999, Journal of arachology）。5)通过在日本琉球群岛和九州岛的野外调查，鉴定出了鲤科七烷属2个属16种。2001年在萨尔茨堡举行的德国国际蜘蛛技术大会上，对它们的动物地理和生物学特征以及地质历史进行了讨论和介绍。

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.
