【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。更多还原

【Abstract】 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.更多还原
