In highly specialised phytophagous insects, important insights on phylogeny of the involved insect group can be often inferred from the evolutionary history of their host plants, and vice-versa, as in the case for a new, peculiar species of pollen beetles, recently discovered in Central China (Hubei Province). This new species is described herein as Teucriogethes huangae Liu & Audisio, sp. nov., and information on its ecology and systematic position is provided. The new species, associated as larvae with a strongly isolated member of the genus Teucrium L. (Lamiaceae), T. ornatum Hemsl., exhibiting a problematic taxonomic position, represents in turn an isolated and morphologically rather aberrant taxon in its lineage, probably the largest in size (2.2-2.8mm), and the first endemic representative of its genus in the whole Eastern Palaearctic. An updating of the taxonomic assessment of members of Teucriogethes and on possible evolutionary relationships with their larval host plants, based on an integrative taxonomy approach, is finally presented. A key to identification of all known species is also introduced. ZooBank: urn:lsid:zoobank.org:pub:E349044B-29A5-416C-85CA-56143C7A29BE.
在高度特化的植食性昆虫中，通过研究其寄主植物的进化历史，通常可以对涉及的昆虫类群的系统发育有深入的了解，反之亦然，就像最近在中国中部（湖北省）发现的一种新型、奇特的花粉甲虫一样。本文描述了一种新种，即中华黄粉甲 Teucriogethes huangae Liu & Audisio，sp. nov.，并提供了其生态学和系统发育位置的信息。该新种的幼虫与一个高度隔离的天蓝绣球属（Lamiaceae）成员，即秀丽天蓝绣球 Teucrium ornatum Hemsl. 相关联，后者的分类地位存在问题。该新种在其谱系中是一个孤立的、形态相当异常的类群，可能是最大的（2.2-2.8 毫米），也是整个东洋古北界该属的第一个特有代表。最后，根据综合分类学方法，对 Teucriogethes 成员的分类评估以及与它们的幼虫寄主植物的可能进化关系进行了更新。还介绍了一种鉴定所有已知物种的关键方法。ZooBank：urn:lsid:zoobank.org:pub:E349044B-29A5-416C-85CA-56143C7A29BE。
