The grasshopper family Pyrgomorphidae is one of the most colorful orthopteran lineages, and includes biologically fascinating and culturally important species. Recent attempts to reconstruct the phylogeny of this family have resulted in a large degree of conflicts between a morphology-based study and a molecular-based study, mainly due to convergent morphological traits that affected phylogenetic reconstruction. In this study, a molecular phylogeny of Pyrgomorphidae based on 32 ingroup species and mitochondrial genome data is proposed, which is used to test the monophyly of the taxonomic groupings used in the current classification scheme. Using the ancestral character state reconstruction analyses and character mapping, we demonstrate that some of the morphological characters, including the male genitalia, which were considered to be taxonomically important, have evolved convergently across the phylogeny. We discuss the discrepancies between our phylogeny and the previous studies and propose an approach to establish a natural classification scheme for Pyrgomorphidae.
菱蝗科是直翅目最具色彩的谱系之一，包括具有生物学吸引力和文化重要性的物种。最近对该科系统发育的重建尝试导致了基于形态学的研究和基于分子的研究之间的很大程度的冲突，主要是由于形态趋同特征影响了系统发育重建。在这项研究中，基于 32 个内群物种和线粒体基因组数据提出了菱蝗科的分子系统发育，用于测试当前分类方案中使用的分类群分组的单系性。通过祖先特征状态重建分析和特征映射，我们证明了一些形态特征，包括被认为具有分类重要性的雄性生殖器，在整个系统发育中已经趋同进化。我们讨论了我们的系统发育与以前研究之间的差异，并提出了一种建立菱蝗科自然分类方案的方法。
