Abstract

Despite considerable research efforts in recent years, the deeper phylogenetic relationships among skipper butterflies (Hesperiidae) remain unresolved. This is primarily because of limited sampling, especially within Asian and African lineages. In this study, we consolidated previous data and extensively sampled Asian and African taxa to elucidate the phylogenetic relationships within Hesperiidae. The molecular dataset comprised sequences from two mitochondrial and two nuclear gene regions from 563 species that represented 353 genera. Our analyses revealed seven subfamilies within Hesperiidae: Coeliadinae, Euschemoninae, Eudaminae, Pyrginae, Heteropterinae, Trapezitinae, and Hesperiinae. The systematics of most tribes and genera aligned with those of prior studies. However, notable differences were observed in several tribes and genera. Overall, the position of taxa assigned to incertae sedis in Hesperiinae is largely clarified in this study. Our results strongly support the monophyly of the tribe Tagiadini (Pyrginae), and the systematics of some genera are clarified with comprehensive discussion. We recognize 15 tribes within the subfamily Hesperiinae. Of these, nine tribes are discussed in detail: Aeromachini, Astictopterini, Erionotini, Unkanini (new status), Ancistroidini, Ismini (confirmed status), Plastingini (new status), Gretnini (confirmed status), and Eetionini (confirmed status). We propose four subtribes within Astictopterini: Hypoleucina subtrib.n., Aclerosina, Cupithina, and Astictopterina. Furthermore, we describe a new genus (Hyarotoides gen.n.) and reinstate two genera (Zea reinst.stat. and Sepa reinst.stat.) as valid. Additionally, we propose several new combinations: Zea mytheca comb.n., Sepa bononia comb.n. & reinst.stat., and Sepa umbrosa comb.n. This study, with extensive sampling of Asian and African taxa, greatly enhances the understanding of the knowledge of the skipper tree of life.

以亚洲和非洲属种为重点的鳞翅目分子系统发育。
尽管近年来开展了大量研究工作,但蹼蝶(Hesperiidae)之间更深层次的系统发育关系仍未得到解决。这主要是因为取样有限,尤其是在亚洲和非洲品系中。在本研究中,我们整合了之前的数据,并对亚洲和非洲的分类群进行了广泛采样,以阐明蝶科(Hesperiidae)内部的系统发育关系。分子数据集包括代表 353 个属的 563 个物种的两个线粒体和两个核基因区的序列。我们的分析揭示了 Hesperiidae 中的七个亚科:Coeliadinae、Euschemoninae、Eudaminae、Pyrginae、Heteropterinae、Trapezitinae 和 Hesperiinae。大多数科和属的系统学与之前的研究一致。然而,在几个科和属中也发现了明显的差异。总体而言,本研究在很大程度上澄清了被归入 Hesperiinae 的分类群的位置。我们的研究结果有力地支持了 Tagiadini 支(Pyrginae)的单系性,并对一些属的系统学进行了全面的讨论。我们确认了 Hesperiinae 亚科中的 15 个部落。我们对其中的 9 个支系进行了详细讨论:Aeromachini、Astictopterini、Erionotini、Unkanini(新地位)、Ancistroidini、Ismini(已确认地位)、Plastingini(新地位)、Gretnini(已确认地位)和 Eetionini(已确认地位)。我们在 Astictopterini 中提出了四个亚属:Hypoleucina subtrib.n.、Aclerosina、Cupithina 和 Astictopterina。此外,我们描述了一个新属(Hyarotoidesgen.n.),并恢复了两个属(Zeareinst.stat. 和 Separeinst.stat.)的有效地位。此外,我们还提出了几个新的组合:这项研究对亚洲和非洲分类群进行了广泛取样,极大地增强了对虹彩蝶生命树知识的了解。

期刊介绍: Molecular Phylogenetics and Evolution is dedicated to bringing Darwin''s dream within grasp - to "have fairly true genealogical trees of each great kingdom of Nature." The journal provides a forum for molecular studies that advance our understanding of phylogeny and evolution, further the development of phylogenetically more accurate taxonomic classifications, and ultimately bring a unified classification for all the ramifying lines of life. Phylogeographic studies will be considered for publication if they offer EXCEPTIONAL theoretical or empirical advances.
