Study on the fauna of the northeastern Indochinese Peninsula - in relation to the Japanese fauna

在1997年至1999年的148天里，12名日本科学家和5名越南科学家参加了该项目，在越南北部的一些地方，包括Tam Dao山、Pia Oak山、Ba Be、Ha Giang、Sa Pa、Son La、Cuc Phuong和Que Phong，调查了昆虫、蜘蛛和其他陆生无脊椎动物。截至目前，该项目已在昆虫科、鳞翅目(6)、鞘翅目(4)、双翅目(2)、翅虫目(1)、膜翅目(1)发表学术论文15篇；蛛形纲，蛛形纲(1)。越南和日本在一些类群上有相似之处，如蜘蛛目七爪目和鞘翅目三爪目。利用线粒体DNA序列对分布于印度支那至日本的甲壳甲亚属Apotomopterus进行了系统发育分析；在此基础上，提出了一个新的系统发育系统，并讨论了该类群的多样性。越南科学家和日本科学家在这个项目上通力合作。小和田博士与河内农业大学昆虫学专业的工作人员和学生共同举办了昆虫学分类论坛会。他亦与桂芳国家公园的护林员讨论研究和保育该地区的自然环境。1999年6月12日至22日，越南研究人员河光雄教授访问日本，就该项目的成果进行讨论，并在未来进一步开展合作研究。

In the total of 148 days from 1997 to 1999, twelve Japanese and five Vietnamese scientists participated in this project and surveyed the fauna of insects, spiders and the other terrestrial invertebrates in some localities in northern Vietnam, including Mt. Tam Dao, Mt. Pia Oak, Ba Be, Ha Giang, Sa Pa, Son La, Cuc Phuong and Que Phong. As the result of this research project, fifteen scientific papers have been published up to now in the following group : Insecta, Lepidoptera (6), Coleopera (4), Diptera (2), Odonata (1), Hymenoptera(1) ; Arachnida, Araneae (1). The faunistic similarity between Vietnam and Japan was suggested on some groups, for example, Heptathela (Araneae) and Triomicrus (Coleoptera). A phylogenetic analysis using mitochondrial DNA sequences was made on the carabid beetle subgenus Apotomopterus distributed from Indochina to Japan ; as the result, a new phylogenetic system was proposed and the diversification of this group was discussed.The Vietnamese and the Japanese scientists worked together cooperatively in this project. A forum on taxonomic works of entomology was made by Dr. Owada with the staffs and students of entomology in the Hanoi Agricultural University. He also discussed with the rangers of the Cuc Phuong National Park on the study and conservation of nature in this area. In 12-22th Jun. 1999, the Vietnamese investigator, Prof. Ha Quang Hung visited Japan for discussing on the results of this project and further cooperative studies in future.
