A multigene phylogenetic study was carried out to test current, mostly morphology‐based hypotheses on Sterrhinae phylogeny with additional material included from further geographical areas and morphologically different lineages. A maximum likelihood analysis (11 molecular markers and 7665 bp) was conducted on 76 species and 41 genera using iq‐tree software. The resulting phylogenetic hypothesis is well resolved and branches have high support values. Results generally agree with earlier hypotheses at tribal levels and support the hypothesis that Sterrhinae comprises two major lineages. Based on the molecular phylogeny and extensive morphological examination, nine tribes are considered valid and the following taxonomic changes are introduced to recognize monophyletic groups: Mecoceratini Guenée, 1858 (= Ametridini Prout, 1910) is transferred from Desmobathrinae to Sterrhinae, and it is considered valid at tribal level new classification; Haemaleini Sihvonen & Brehm is described as a new tribe and deemed sister to Scopulini + Lissoblemmini; Lissoblemmini Sihvonen & Staude is described as a new tribe and sister to Scopulini; Lythriini Herbulot, 1962 is now a junior synonym of Rhodometrini Agenjo, 1952 syn.n.; and Rhodostrophiini Prout, 1935 is now a junior synonym of Cyllopodini Kirby, 1892 syn.n. In addition, 48 taxa are transferred from other geometrid subfamilies to Sterrhinae, or within Sterrhinae from one tribe to another, or they are classified into a tribe for the first time, or a new genus classification is proposed. The results demonstrate the limited explanatory power of earlier classifications, particularly at the tribal level. This is probably a result of earlier classifications being based on superficial characters and biased towards the European and North American fauna. The species richness and distribution of Sterrhinae and its constituent tribes are reviewed, showing that the globally distributed Sterrhinae are most diverse in the Neotropics (31% of global fauna). They are species‐rich in the Palaearctic (22%), Afrotropics (19%) and Indo‐Malay (16%) regions, whereas they are almost absent in Oceania (1%). In terms of the described fauna, the most species‐rich tribes are Scopulini (928 species), Sterrhini (876 species) and Cosymbiini (553 species), all of which have a cosmopolitan distribution. Mecoceratiini and Haemaleini are almost entirely Neotropical. Timandrini and Lissoblemmini, by contrast, are absent in the Neotropics. We present a revised classification of the global Sterrhinae fauna, which includes about 3000 putatively valid species, classified into nine tribes and 97 genera. Four genera are of uncertain position within Sterrhinae. Our results highlight the compelling need to include more genera from a global perspective in molecular phylogenetic studies, in order to create a stable global classification for this subfamily.

Sterrhinae 蛾(鳞翅目:几何科)的分子系统发育:走向全球分类

进行了多基因系统发育研究,以测试当前的、主要基于形态学的关于链球菌系统发育的假设,其中包括来自其他地理区域和形态不同谱系的额外材料。使用 iq-tree 软件对 76 个物种和 41 个属进行了最大似然分析(11 个分子标记和 7665 bp)。由此产生的系统发育假设得到了很好的解决,并且分支具有很高的支持值。结果通常与部落级别的早期假设一致,并支持 Sterrhinae 包含两个主要谱系的假设。基于分子系统发育和广泛的形态学检查,九个部落被认为是有效的,并引入了以下分类学变化来识别单系群体:Mecoceratini Guenée,1858(= Ametridini Prout,1910) 从 Desmobathrinae 转移到 Sterrhinae,并被认为在部落级别新分类中有效;Haemaleini Sihvonen & Brehm 被描述为一个新部落,被认为是 Scopulini + Lissoblemmini 的姐妹;Lissoblemmini Sihvonen & Staude 被描述为 Scopulini 的新部落和姐妹;Lythriini Herbulot, 1962 现在是 Rhodometrini Agenjo, 1952 syn.n. 的次要同义词;和 Rhodostrophiini Prout, 1935 现在是 Cyllopodini Kirby, 1892 syn.n 的次要同义词。此外,48个类群从其他几何亚科转移到Sterrhinae,或在Sterrhinae内从一个部落转移到另一个部落,或首次归入一个部落,或提出新的属分类。结果表明早期分类的解释力有限,尤其是在部落层面。这可能是早期分类基于表面特征并偏向于欧洲和北美动物群的结果。回顾了 Sterrhinae 及其组成部落的物种丰富度和分布,表明全球分布的 Sterrhinae 在新热带地区最为多样化(占全球动物群的 31%)。它们在古北 (22%)、非洲热带 (19%) 和印度-马来 (16%) 地区物种丰富,而在大洋洲 (1%) 几乎不存在。就所描述的动物群而言,物种最丰富的部落是 Scopulini(928 种)、Sterrhini(876 种)和 Cosymbiini(553 种),它们都具有世界性的分布。Mecoceratiini 和 Haemaleini 几乎完全是新热带的。相比之下,Timandrini 和 Lissoblemmini 则不在新热带地区。我们提出了全球 Sterrhinae 动物群的修订分类,其中包括大约 3000 个假定有效的物种,分为 9 个部落和 97 个属。四个属在 Sterrhinae 中的位置不确定。我们的结果强调了在分子系统发育研究中从全球角度包括更多属的迫切需要,以便为该亚科创建一个稳定的全球分类。
