Trapezitinae skippers are restricted to Australia and New Guinea. Despite decades of taxonomic work, their systematics and phylogeny remain little understood. To resolve the composition of genera and determine their evolutionary relationships, we inferred a comprehensive multilocus molecular phylogeny of Trapezitinae. Our results recover a monophyletic Trapezitinae as sister to Barcinae, with a poorly resolved backbone possibly indicating an early rapid radiation. We recover two main clades comprising all currently described genera, including the previously contentious Prada Evans, 1949 but excluding Tiacellia Evans, 1949. Several genera are recovered as paraphyletic or polyphyletic, rendering the classification of Trapezitinae incompatible with the new phylogeny. Therefore, we synonymize Motasingha Watson, 1893 syn. nov. and Oreisplanus Waterhouse & Lyell, 1914 syn. nov. with Hesperilla Hewitson, 1868 and Neohesperilla Waterhouse & Lyell, 1914 syn. nov. with Toxidia Mabille, 1891. To reflect the placement of Anisynta dominula outside of Anisynta, we describe the new genus Atkinsia Braby & Toussaint gen. nov., which includes the sole species Atkinsia dominula (Plötz, 1884) comb. nov. Two species of Toxidia and two species of Signeta Waterhouse & Lyell, 1914 are placed into Timoconia Strand, 1909, yielding four new combinations: Timoconia melania (Waterhouse, 1903) comb. nov., Timoconia peron (Latreille, 1824) comb. nov., Timoconia flammeata (Butler, 1882) comb. nov. and Timoconia tymbophora (Meyrick & Lower, 1902) comb. nov. Thus, Signeta Waterhouse & Lyell, 1914 syn. nov. is now regarded as a junior synonym of Timoconia. Overall, our phylogeny has provided the basis for 20 nomenclatural changes at the species and subspecies level, including 14 new combinations.

蝴蝶亚科梯形亚科（鳞翅目：蝶形亚科：橙子科）的分子系统发育、系统学和类属分类

Trapezitinae 船长仅限于澳大利亚和新几内亚。尽管进行了数十年的分类学工作，但它们的系统学和系统发育仍然知之甚少。为了解决属的组成并确定它们的进化关系，我们推断了 Trapezitinae 的全面多位点分子系统发育。我们的结果恢复了作为 Barcinae 的姊妹的单系梯形亚目，其主干解析不佳可能表明早期快速辐射。我们恢复了包含所有当前描述的属的两个主要进化枝，包括以前有争议的 Prada Evans，1949 年，但不包括 Tiacellia Evans，1949 年。几个属被恢复为并系或多系，使得梯形亚科的分类与新的系统发育不相容。因此，我们将 Motasingha Watson，1893 同义词。十一月 和 Oreisplanus Waterhouse & Lyell，1914 年同义词。十一月 与 Hesperilla Hewitson，1868 年和 Neohesperilla Waterhouse & Lyell，1914 年同步。十一月 与 Toxidia Mabille 合作，1891 年。为了反映 Anisynta dominula 在 Anisynta 之外的位置，我们描述了新属 Atkinsia Braby & Toussaint gen。nov.，其中包括唯一的物种 Atkinsia dominula (Plötz, 1884) 梳。十一月 将两种 Toxidia 和两种 Signeta Waterhouse & Lyell，1914 年放入 Timoconia Strand，1909 年，产生四种新组合：Timoconia melania（Waterhouse，1903 年）梳子。十一月，Timoconia peron (Latreille, 1824) 梳子。11 月，Timoconia flammeata (Butler, 1882) 梳子。十一月 和 Timoconia tymbophora (Meyrick & Lower, 1902) 梳子。十一月 因此，Signeta Waterhouse 和 Lyell，1914 年同义词。十一月 现在被视为 Timoconia 的初级同义词。全面的，
