盔唇瓢虫族(鞘翅目:瓢虫科)系统分类研究进展

Research progress on systematic taxonomy of Chilocorini (Coleoptera: Coccinellidae)

盔唇瓢虫族昆虫是瓢虫科中一类重要的捕食性天敌,主要捕食介壳虫,是该类害虫的重要生物防治天敌。盔唇瓢虫族昆虫研究历史悠久,目前世界盔唇瓢虫族包括22属超过280种,其中有9属42种分布在中国。该族许多属建立时间早,鉴别特征的原始描述不够详细,导致属间界定模糊,属的地位时常受到质疑且变动频繁。一些种类丰富,形态多变、且分布广泛的属如盔唇瓢虫属、光缘瓢虫属仍缺少世界性的订正研究。随着瓢虫科分子系统发育研究的开展,瓢虫科经典分类系统受到了较大的挑战,而盔唇瓢虫亚科已被证实为非单系起源的类群。目前,将盔唇瓢虫族归入瓢虫亚科得到绝大多数瓢虫科分子系统发育研究的支持,但与其它类群的亲缘关系仍存争议。尽管已有研究对盔唇瓢虫族现存所有属的系统发育关系进行了分析,但部分类群缺少分子数据,导致这些类群在该族系统发育关系中的位置并不明确。本文回顾了国内外盔唇瓢虫族的分类历史,记述了目前该族在瓢虫科的分类地位以及族下系统发育关系进展,最后对盔唇瓢虫族分类研究存在的问题及未来研究进行了展望。

Ladybirds of the tribe Chilocorini prey mainly on coccids.Many species of this tribe are economically important as they are widely used as biological control agents.Currently,Chilocorini includes 22 genera and more than 280 species in the world,among which 42 species in 9 genera are distributed in China.Many genera in this tribe were established before the 19 th century,and the original description of the distinguishing characters were not detailed enough,which due to the definition of the genera was controversial and the status of the genera had been queried and changed frequently.Some group such as Chilocorus and Exochomus with species richness,heterogeneous morphological characters and widely distributed,still lack worldwide revision studies.Along with the development of research on the molecular phylogeny of Coccinellidae,the rationality of the traditional classification system of Coccinellidae has been greatly challenged.Most studies have indicated that the subfamily Chilocorinae is not a monophyletic group.Chilocorini belong to the subfamily Coccinellidae is supported by most of the phylogenetic studies of Coccinellidae,but there is no consensus concerning the relationships between Chilocorini and other group.Until now,the phylogenetic relationships of all the existing genera of Chilocorini have been reconstructed.However,the relationship of some genera to other group of Chilocorini remains unclear,because of the molecular data absence of these genera in the phylogenetic analysis.In this study,the taxonomic history of Chilocorini was reviewed.Current taxonomic status of this tribe in Coccinellidae and the progress of its phylogenetic relationship under the tribe were summarized.Finnaly,the existing problems and research prospects were discussed to provide reference for the future related research.
