The phylogenetic relationships within the beetle family Cucujidae were investigated for the first time. Fifty‐seven morphological characters were used for maximum parsimony and Bayesian analyses. Mitochondrial genomes were generated from museum specimens through genome skimming and used for phylogenetic analyses in a maximum likelihood framework due to the difficulty in collecting many of the Cucujidae species and the lack of availability of ethanol‐preserved specimens. Both morphological and molecular analyses supported the monophyly of the four established genera: Cucujus Fabricius, Pediacus Shuckard, Palaestes Perty, and Platisus Erichson. They also led to the description of a new genus, Thesaurus gen.n., from South America, and the recognition of two new subfamilies, Pediacinae subfam.n. and Platisinae subfam.n. Diagnoses of Cucujidae subfamilies and genera are provided along with illustrations and keys for their identification. Phylogenetic relationships between the genera were analysed and discussed based on morphological and molecular data. Three new species were described in Thesaurus gen.n.: T. albertalleni gen. et sp.n. from Venezuela, T. zaitsevi sp.n. from Peru, and T. macclarini sp.n. from Ecuador. Illustrations and a key to species are provided. The previously unknown larvae of Palaestes and Thesaurus are illustrated and described for the first time. The Eocene fossil species, Platisus punctatus (Ramírez, Corsolini & Di Iorio), from Patagonia, Argentina, is here transferred to the genus Thesaurus.

扁皮甲虫（鞘翅目：葫芦科）的综合系统发育，具有修订的分类和一个新的南美属

首次研究了甲虫科Cucujidae 内的系统发育关系。57 个形态特征用于最大简约和贝叶斯分析。由于难以收集许多葫芦科物种且缺乏乙醇保存的标本，线粒体基因组是通过基因组撇取从博物馆标本中生成的，并用于最大似然框架中的系统发育分析。形态学和分子分析都支持四个既定属的单一性：Cucujus Fabricius、Pediacus Shuckard、Palaestes Perty 和 Platisus Erichson。他们还导致了对来自南美洲的新属 Thesaurus gen.n. 的描述，以及对两个新亚科 Pediacinae subfam.n. 的认可。和 Platisinae subfam.n. 提供了葫芦科亚科和属的诊断以及用于识别它们的插图和关键。基于形态和分子数据分析和讨论了属之间的系统发育关系。同义词 gen.n. 中描述了三个新物种：T. albertalleni gen。et sp.n. 来自委内瑞拉，T. zaitsevi sp.n. 来自秘鲁，和 T. macclarini sp.n. 来自厄瓜多尔。提供了插图和物种的关键。首次说明和描述了以前未知的 Palaestes 和叙词表幼虫。来自阿根廷巴塔哥尼亚的始新世化石物种 Platisus punctatus（Ramírez、Corsolini 和 Di Iorio）在这里被转移到同义词库中。基于形态和分子数据分析和讨论了属之间的系统发育关系。同义词 gen.n. 中描述了三个新物种：T. albertalleni gen。et sp.n. 来自委内瑞拉，T. zaitsevi sp.n. 来自秘鲁，和 T. macclarini sp.n. 来自厄瓜多尔。提供了插图和物种的关键。首次说明和描述了以前未知的 Palaestes 和叙词表幼虫。来自阿根廷巴塔哥尼亚的始新世化石物种 Platisus punctatus（Ramírez、Corsolini 和 Di Iorio）在这里被转移到同义词库中。基于形态和分子数据分析和讨论了属之间的系统发育关系。同义词 gen.n. 中描述了三个新物种：T. albertalleni gen。et sp.n. 来自委内瑞拉，T. zaitsevi sp.n. 来自秘鲁，和 T. macclarini sp.n. 来自厄瓜多尔。提供了插图和物种的关键。首次说明和描述了以前未知的 Palaestes 和叙词表幼虫。来自阿根廷巴塔哥尼亚的始新世化石物种 Platisus punctatus（Ramírez、Corsolini 和 Di Iorio）在这里被转移到同义词库中。提供了插图和物种的关键。首次说明和描述了以前未知的 Palaestes 和叙词表幼虫。来自阿根廷巴塔哥尼亚的始新世化石物种 Platisus punctatus（Ramírez、Corsolini 和 Di Iorio）在这里被转移到同义词库中。提供了插图和物种的关键。首次说明和描述了以前未知的 Palaestes 和叙词表幼虫。来自阿根廷巴塔哥尼亚的始新世化石物种 Platisus punctatus（Ramírez、Corsolini 和 Di Iorio）在这里被转移到同义词库中。
