摘要

摘要Rhytiphora Audinet Serville，1835是澳大利亚种类最多的长角甲虫属（Cerambycidae Latreille，1802），约有200种（来自近40个以前的属，现在同义为一个）分布在整个大陆。我们利用全基因组鸟枪测序和博物馆标本的COI条形码的线粒体基因组数据，重建了68种Rhytiphora物种的系统发育，并分析了形态多样性和生物地理学历史。我们发现了一个单系Rhytiphora，包含两个不同的分支，其中所有以前的属（除了Achriotypa Pascoe，1875）都是副系的。9个形态特征（包括体型和雄性刚毛“性斑块”）显示出强烈的系统发育信号，可用于区分两个分支。一个分支主要局限于澳大利亚的热带北部，而另一个较大的分支在中西东海岸有许多物种。两个分支都经历了多次生物群落变化，在栖息地占用方面表现出非凡的灵活性。

Rhytiphora: a phylogenetic and morphological study of Australia’s largest longhorn beetle genus (Coleoptera: Cerambycidae)

ABSTRACT Rhytiphora Audinet-Serville, 1835 is the most speciose longhorn beetle (Cerambycidae Latreille, 1802) genus in Australia, with ~200 species (from nearly 40 former genera, now synonymised into one) distributed across the entire continent. We used mitochondrial genome data from whole genome shotgun sequencing and COI barcoding of museum specimens to reconstruct the phylogeny of 68 Rhytiphora species, and analysed the morphological diversity and biogeographic history. We recovered a monophyletic Rhytiphora containing two distinct clades, within which all of the former genera (except Achriotypa Pascoe, 1875) are paraphyletic. Nine morphological traits (including body size and the male setose ‘sex patches’) show strong phylogenetic signal and can be used to differentiate between the two clades. One clade is mainly restricted to Australia’s tropical north, whereas the other, larger clade has many species along the mesic east coast. Both clades have experienced multiple biome shifts, displaying a remarkable flexibility in habitat occupancy.

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.
