中国吉丁亚科分类修订（鞘翅目：吉丁虫科）

The family Buprestidae (Coleoptera, Buprestoidea), commonly known as jewel beetles, is always a concern for its brilliant body color, serious harm and used for decorative and medicinal resources, etc. Buprestinae is a highly diverse subfamily, up to the present, 20 tribe and 115 genera are recognized and more than 3200 species have been reported, of these, only 8 tribe and 13 genera contains 117 species have previously been known from China. Among these species, some are important forest pests, and more than half species have economic value by potential useful for plant pollination. However, there are lots of prominent problems existed in Chinese Buprestinae taxonomy, such as species numbers unclear; taxonomic positions of some taxa uncertain; some species, especially which have important economic significance, were used an invalid name for a long time; and the studies of the faunistics and geographic divergence not plenty. Hence, the present project aims to enrich the Buprestinae species resources data through faunistic investigation and comparative morphology, to revise taxa of Chinese Buprestinae according to the newest classification system and research findings. We also try to analyze the geographic distribution pattern of Chinese Buprestinae to obtain a new understanding on faunistic formation and divergence. The results of this project will close the gap of Buprestinae research level between China and the World and be useful for forestry, horticulture, inspection and quarantine.

吉丁科昆虫因绚丽的体色、严重的危害性和作为装饰及药用资源等而长期受到人们关注。吉丁亚科全球已知20族115属3200余种，中国记录8族13属117种。我国该亚科部分种类为重要的林木害虫，且超过半数是潜在的传粉昆虫，具有经济和生态价值。目前我国该亚科分类存在的突出问题是：物种资源本底不清，分类编目落后；一些类群的分类地位存在较大争议；一些经济意义重要的种类长期使用了同物异名；对其在我国的区系形成、分化和生物地理学缺乏研究。针对上述问题，本项目旨在通过更广泛的区系调查和比较形态学研究，进一步了解我国该类昆虫资源种类和数量；应用最新的分类体系，对我国吉丁亚科各级阶元进行整理和修订；通过对该亚科现有地理分布格局的分析，对其在我国的区系形成和分化产生新的认识。本项研究的综合成果将缩小我国该亚科分类与国际整体研究的巨大差距，并为林业、园艺、检验检疫等领域提供参考。

吉丁亚科昆虫中，既有潜在的传粉昆虫，也有重要的蛀干害虫，其生物学特性独特，是很好的研究对象。本亚科种类数量我国原记录117种，至项目截止，记录物种数增加到146种（不包含未发表新物种）。项目执行过程中，吉丁亚科标本增加1300多号，并同时获取了大量生态照、寄主信息及一些珍稀种类的标本。发表SCI学术论文6篇，会议论文1篇，接收SCI学术论文2篇，共描述了3新属9新种，确认了6种成虫的新寄主，增加了中国新记录亚属1个，新记录种4个。完善了文献资料库，明确了18个物种在26个省份的新分布记录，并有12个新种待发表。探讨了该亚科特有种比例高的可能原因，提出了早期星吉丁属物种的鉴定结果需要慎重使用。本项目的开展，将对我国吉丁亚科分类工作的推进有重要作用。
