Abstract

ABSTRACT Some fossil Cantharidae from the Burmese amber have been reported, but it is still a poorly investigated group and some unknown taxa remain to be discovered. In this study, we employed comparative morphology and geometric morphometrics to uncover a new catharid genus from the mid-Cretaceous Burmese amber, and further investigate its phylogenetic position within Cantharidae by different cladistic methods. As a result, Brevipterus gen. nov., was defined to accommodate B. strungei (Fanti & Damggard, 2019) comb. nov. transferred from Sanaungulus and another three new species, B. acutiapicis sp. nov., B. abtusiapicis sp. nov. and B. megacephalus sp. nov., and the produced topologies indicate that the new genus is always grouped together with other members of the subfamily Cantharinae. These results will improve our knowledge about Burmite cantharids and provide some more early evidence in reconstructing the phylogeny of Cantharidae.

形态学和几何形态测量学揭示了中白垩世缅甸琥珀中蚁甲科(鞘翅目，蚁总科)的新属，并对其系统发育位置进行了初步研究

摘要缅甸琥珀中的斑蝥科化石已被报道，但它仍是一个研究较少的类群，还有一些未知的分类群有待发现。在本研究中，我们采用比较形态学和几何形态计量学的方法，从白垩纪中期的缅甸琥珀中发现了一个新的卡塔属，并通过不同的分支方法进一步研究了其在斑蝥科中的系统发育位置。因此，Brevipterus gen.nov.被定义为适应B.strungei（Fanti&Damggard，2019）梳。从Sanaugulus和另外三个新种，B.acutiapicis sp.nov.，B.abtusiapicis sp.nov..和B.megacephalus sp.novs.转移而来，所产生的拓扑结构表明该新属总是与Cantharinae亚科的其他成员聚在一起。这些结果将提高我们对Burmite斑蝥的认识，并为重建斑蝥科的系统发育提供更多的早期证据。

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.
