Abstract Mycteridae are a small group of Tenebrionoidea, comprising three subfamilies and over 180 species. Eurypinae are the most species-rich subfamily, with diverse external morphology of adults at both generic and species levels. To date, no study of mycterid systematics using phylogenetic approaches has been conducted. In this paper, we reconstruct a phylogeny of eurypine beetles based on morphological characters, covering most described genera. This is the first attempt to investigate the evolution and relationships of Mycteridae. The phylogenetic positions of several systematically enigmatic genera can thus be hypothesized based on the topology. Recent molecular phylogenetic frameworks and fossil records reveal that most eurypine lineages probably evolved during the Late Mesozoic to Early Cenozoic. Our results also indicate that the fauna of the current regions of the world and Early Cenozoic Europe consist(ed) of various eurypine lineages, supporting the previously proposed hypothesis that Eurypinae were once widely distributed, but underwent a subsequent partial extinction. Two new genera and three new species are described from Australia, based on comparative anatomy and cladistic analysis, namely Austroconomorphus slipinskii gen. et sp. nov., Austrophaeogala lawrencei gen. et sp. nov. and Austrophaeogala ovipennis sp. nov. We demonstrate that the phylogenetic diversity of Mycteridae in Australia is greater than previously suspected.

基于形态学的椭圆形棕榈和花甲虫（鞘翅目：Mycteridae：Eurypinae）的系统发育，以及来自澳大利亚的新属和新种的描述

摘要 Mycteridae是Tenebrionoidea的一小群，包括三个亚科和180多个物种。Eurypinae 是物种最丰富的亚科，在属和种水平上具有不同的成虫外部形态。迄今为止，尚未进行使用系统发育方法对菌类系统学的研究。在本文中，我们基于形态特征重建了欧洲甲虫的系统发育，涵盖了大多数描述的属。这是研究菌科的进化和关系的第一次尝试。因此，可以根据拓扑结构假设几个系统性神秘属的系统发育位置。最近的分子系统发育框架和化石记录表明，大多数欧洲人的谱系可能是在中生代晚期到新生代早期进化的。我们的研究结果还表明，世界当前地区和早期新生代欧洲的动物群由各种欧陆亚科谱系组成，支持先前提出的欧陆亚科曾经广泛分布的假设，但随后经历了部分灭绝。基于比较解剖学和分支分析，从澳大利亚描述了两个新属和三个新种，即 Austroconomorphus slipinskii gen。等人。十一月，Austrophaeogala Lawrencei gen。等人。十一月 和 Austrophaeogala ovipennis sp。十一月 我们证明了澳大利亚 Mycteridae 的系统发育多样性比以前怀疑的要大。但随后经历了部分灭绝。基于比较解剖学和分支分析，从澳大利亚描述了两个新属和三个新种，即 Austroconomorphus slipinskii gen。等人。十一月，Austrophaeogala Lawrencei gen。等人。十一月 和 Austrophaeogala ovipennis sp。十一月 我们证明了澳大利亚 Mycteridae 的系统发育多样性比以前怀疑的要大。但随后经历了部分灭绝。基于比较解剖学和分支分析，从澳大利亚描述了两个新属和三个新种，即 Austroconomorphus slipinskii gen。等人。十一月，Austrophaeogala Lawrencei gen。等人。十一月 和 Austrophaeogala ovipennis sp。十一月 我们证明了澳大利亚 Mycteridae 的系统发育多样性比以前怀疑的要大。
