摘　　要：星吉丁属Chrysobothris隶属鞘翅目Coleoptera吉丁科Buprestidae,多数星吉丁是重要的农林业害虫。文章对陕西省4种常见星吉丁(锦星吉丁C.pulchripes、中华星吉丁C.sinensis、白氏星吉丁C.shirakii和桔星吉丁C.mandarina)的外部形态和雄性生殖器进行比较研究。结果表明:这4种星吉丁在外部形态特征(头部、前胸背板、前胸腹板突、鞘翅)及阳茎结构特征存在显著差异,可作为物种鉴定的主要依据。此外,本文提供了这4种星吉丁的整体图、局部特征图及分种检索表。The genus Chrysobothris belongs to the family Buprestidae of Coleoptera,and most of them are important agricultural and forestry pests.In this study,the external morphology and male genitalia of 4 common species of the genus Chrysobothris(C.pulchripes,C.sinensis,C.shirakii,and C.mandarina)from Shaanxi Province,China were compared.The results showed that the 4 species had significant differences in both external characters(head,pronotum,prosternal process and elytra)and aedeagus,and these characters can be used in species identification and taxonomy.Moreover,the photos of habitus and morphology characters,and a key to separate these 4 species were provided.
