Characteristics and Formation of the Pamphiliine Sawfly Fauna of Japan and ger Adjacent Regions (Hymenopters, Pamphiliidac)

1.为丰富以往积累的资料，于1998-2001年6-7月在北海道各地区采集了成虫和幼虫，1999-2000年6-8月在本州中部山区采集了成虫和幼虫，并于2000-2001年5-5月在本州西部初谷山采集了成虫和幼虫。所获得的资料包括一些未被描述的种或日本新记录种。2.编制了世界毛壳亚科的属组和种组分类单元名录。本文记述了一新属--金鱼属，分布于包括日本在内的东亚地区。全世界共有6属160种，其中东亚有4属95种，日本有4属47种。简要回顾了目前有关各分类单元的分类、分布和寄主植物的知识。本文提出了一个新的分类方法，将神经瘤属、眼甲科和海龙属种归为属内种组，并进行了分支分析，提出了最大的海龙属6个世界属和12个种组的系统发育关系假说。在此基础上，试图探讨日本珍稀动物群的历史形成。然而，尚未取得令人满意的结果，这主要是由于缺乏关于日本周围东亚片目动物群的充分信息。要解决这一问题，还需要更多关于东亚海鞘亚科的知识，特别是中国的知识。3.研究过程中的部分新发现已发表在13篇单独的论文中。

1. To enrich the previously accumulated material, adults and larvae of Pamphiliine sawflies were collected in various regions of Hokkaido in June and July, 1998 to 2001, in the mountainous regions of central Honshu inJune to August, 1999 to 2000, and in Chugoku Mountains in western Honshu in May, 2000 and 2001. The material obtained included some undescribed species or species new to Japan.2.A checklist was compiled of the genus group and species group taxa of the subfamily Pamphiliinae of the world. A new genus, Chrysolyda, was described from eastern Asia, including Japan. A total of 160species in six genera are known in the world, of which 95 species in four genera occur in eastern Asiaand 47 species in four generaoccur in Japan. Current knowledge on the taxonomy, distribution, and host plants of each taxon was concisely reviewed. A new classification of the species of Neurotoma, Onycholyda and Pamphilius into intrageneric species-groups was proposed, and a cladistic analysis was performed to present a hypothesis of the phylogenetic relationships of the six world generaand 12 species-groups recognized in the largest genus Pamphilius. Based on this information, attempts were made to consider the historical formation of the Japanese pamphiliine fauna. Satisfactory results have not been obtained, however, mainly due to the lack of adequate information of the pamphiliine fauna of eastern Asia around Japan. More knowledge on the Pamphiliinae of eastern Asia, notably those of China, is needed to solve the problem.3.Part of new findings during the course of the studies have been published in 13 separate papers.
