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

1.为了丰富以前积累的材料，在北海道的各个地区，1998年至2001年6月和7月，在本州中部的山区，1999年至2000年6月至8月，在本州西部的中国山区，2000年和2001年5月的Pamphiliine叶蜂成虫和幼虫收集。2.编制了世界扁叶蜂亚科属组和种组分类单元的名录。在包括日本在内的东亚地区描述了一个新属，Chrysolyda。全世界已知6属160种，其中东亚4属95种，日本4属47种。简要综述了各分类群的分类、分布和寄主植物等方面的研究进展。本文提出了将Neurotoma属、Onycholyda属和Pamphilius属划分为属内种组的新分类方法，并对Pamphilius属中已知的6个世界属和12个种组的系统发育关系进行了分支分析。根据这些信息，试图考虑日本的小册子动物区系的历史形成。然而，由于缺乏对日本周边东亚小卷蛾区系的充分资料，至今尚未取得令人满意的结果。3.研究过程中的部分新发现已发表在13篇论文中。

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.
