The Central American genus Strangalidium Giesbert, 1997 is part of the subfamily Lepturinae, known for the floricolous habits of its species. A phylogenetic analysis was conducted to study the relationships of the species of the genus and other taxa that have been recognized as closely related to it. This study is the first that integrates characters codified with geometric morphometric methods for inferring the phylogeny of any group of Cerambycidae. In our results, Strangalidium is recovered as paraphyletic, forming a clade with Strangalia Dejean. Both genera are synonymized, and the species previously known as Strangalidium, herein transferred to Strangalia, are redescribed. One new species is described from Mexico: Strangalia giesberti sp. nov. from Chiapas. In addition, a key to identify the species is provided. http://zoobank.org/urn:lsid:zoobank.org:pubB8334A76-892D-4E82-900A-58DF02CBCD72 http://zoobank.org/urn:lsid:zoobank.orgact:54B9E3B7-1415-4AF1-8543-A3AEBE34B214

花状长角牛甲虫属 Strangalidium Giesbert（鞘翅目：天牛科）的系统发育修正

中美洲 Strangalidium Giesbert 属，1997 年属于 Lepturinae 亚科，以其物种的花色习性而闻名。进行系统发育分析以研究该属的物种与已被认为与其密切相关的其他分类群的关系。这项研究是第一个将用几何形态测量方法编码的特征整合在一起，以推断任何天牛科的系统发育。在我们的结果中，Strangalidium 作为并系群被回收，与 Strangalia Dejean 形成一个进化枝。两个属都被同义，并且重新描述了以前称为 Strangalidium 的物种，这里转移到 Strangalia。墨西哥描述了一种新物种：Strangalia giesberti sp。十一月 来自恰帕斯州。此外，还提供了识别物种的密钥。http://zoobank.org/urn:lsid:
