Abstract

Ulopinae is a distinctive subfamily of leafhoppers that is widely distributed across the Afrotropical, Palearctic, Indomalayan and Australasian regions. The ulopine fauna of Australia is entirely endemic and includes two tribes of striking appearance, the Ulopini and Cephalelini. Knowledge of these groups is fragmentary and in many instances, no information is available beyond original descriptions. We assess the monophyly, phylogenetic placement and species-level diversity of the Ulopini genus Austrolopa. Phylogenetic analyses based on sequence data from target nuclear loci (18S, 28S, H2A and H3) and mitochondrial genomes (15 genes) for 23 membracoid taxa yielded congruent topologies. Our results provide strong evidence for the monophyly of Ulopinae and a clade consisting of Ulopini + Cephalelini. However, a non-monophyletic Cephalelini arises from within a polyphyletic Ulopini. Austrolopa was strongly recovered as monophyletic in all analyses, a result also supported by morphological features. The genus currently includes six species, three of which are described based on morphological and molecular data: Austrolopa botanica, sp. nov., Austrolopa rotunda, sp. nov. and Austrolopa sublima, sp. nov. A lectotype designation is provided for Austrolopa kingensis Evans, 1937, sp. reval. Our findings illustrate that the Australian Ulopinae is far more diverse than currently circumscribed and several species of Austrolopa are yet to be recognised.

澳大利亚特有 Ulopinae（半翅目：蝉科：Cicadellidae）的系统发生组学

叶蝉亚科（Ulopinae）是一种独特的叶蝉亚科，广泛分布于非洲热带、南北美洲、印度洋和澳大拉西亚地区。澳大利亚的叶蝉动物群完全是地方性的，其中包括两个外形引人注目的部落：Ulopini 和 Cephalelini。对这两个族群的了解非常零散，在许多情况下，除了原始描述外，没有任何其他信息。我们对 Ulopini 属 Austrolopa 的单系、系统发育位置和物种多样性进行了评估。基于 23 个膜翅目类群的目标核位点（18S、28S、H2A 和 H3）和线粒体基因组（15 个基因）的序列数据进行的系统发生分析得出了一致的拓扑结构。我们的研究结果为 Ulopinae 的单系性和由 Ulopini + Cephalelini 组成的支系提供了强有力的证据。然而，一个非单系的 Cephalelini 出现在多系的 Ulopini 中。在所有分析中，Austrolopa 都被认定为单系，形态特征也支持这一结果。该属目前有六个物种，其中三个是根据形态学和分子数据描述的：新种 Austrolopa botanica、新种 Austrolopa rotunda 和新种 Austrolopa sublima。我们还为 Austrolopa kingensis Evans, 1937, sp.我们的研究结果表明，澳大利亚 Ulopinae 的多样性远远超过目前的划分，Austrolopa 的若干种仍有待确认。

期刊介绍： Invertebrate Systematics (formerly known as Invertebrate Taxonomy) is an international journal publishing original and significant contributions on the systematics, phylogeny and biogeography of all invertebrate taxa. Articles in the journal provide comprehensive treatments of clearly defined taxonomic groups, often emphasising their biodiversity patterns and/or biological aspects. The journal also includes contributions on the systematics of selected species that are of particular conservation, economic, medical or veterinary importance. Invertebrate Systematics is a vital resource globally for scientists, students, conservation biologists, environmental consultants and government policy advisors who are interested in terrestrial, freshwater and marine systems. Invertebrate Systematics is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
