Abstract: This study revises the prasinatus species group of the genus Callimerus (Coleoptera, Cleridae), sensu Stenocallimerus Corporaal & Pic, 1940. Ten species are recognized, including one new species, Callimerus modestus sp. nov., from northeastern Vietnam. Two new synonyms are proposed for C. koenigi Pic, 1954 (C. koenigi var. subattenuatus Pic, 1954 syn. nov.; C. taiwanus Miyatake, 1965 syn. nov.), and two for C. prasinatus Lewis, 1896 (C. bicoloripes Pic, 1925 syn. nov.; C. sauteri Corporaal & Pic, 1940 syn. nov.). Callimerus filiformis Gorham, 1903 is excluded from this species group. An identification key is presented, accompanied by illustrations of the type specimens’ habitus, male terminalia, and other diagnostic characters. This revision refines the taxonomy of prasinatus species group and offers a foundation for future research on the group.

Keywords: Callimerus, checkered beetles, identification key, new species, prasinatus group, synonymy, taxonomy

摘要：本研究对丽郭公虫属（鞘翅目：郭公虫科）中的prasinatus种团进行了分类修订。该种团共包含10个物种，其中包括1个新种——Callimerus modestus sp. nov.（分布于越南东北部）。提出四个新异名：C. koenigi var. subattenuatus Pic, 1954和C. taiwanus Miyatake, 1965为C. koenigi Pic, 1954的次异名；C. bicoloripes Pic, 1925和C. sauteri Corporaal & Pic, 1940为C. prasinatus Lewis, 1896的次异名。Callimerus filiformis Gorham, 1903排出此种团。本文提供了prasinatus种团的分种检索表、模式标本的外部形态和雄性外生殖器结构图。本修订工作进一步完善了prasinatus种团的分类体系，为后续相关研究提供了基础。
