本文首次对甲虫科的系统发育关系进行了研究。57个形态学性状进行了最大简约性和贝叶斯分析。线粒体基因组是通过基因组扫描从博物馆标本中生成的，由于收集许多Cucujidae物种的困难和缺乏乙醇保存标本的可用性，该基因组在最大似然框架中用于系统发育分析。形态学和分子分析均支持已建立的四个属：Cucujus Fabricius， Pediacus Shuckard， Palaestes Perty和Platisus Erichson的单一性。它们还导致了一个新属的描述，Thesaurus gen.n。发现了两个新亚科：Pediacinae亚科。和铂亚科。提供了黄瓜科亚科和属的诊断，并附有插图和识别关键字。根据形态和分子资料分析和讨论了属间的系统发育关系。在叙词目gen.n.中发现3新种：t.a bertalleni gen. et sp.n.。来自委内瑞拉的T. zaitsevi sp.n。来自秘鲁的T. macclarini sp.；从厄瓜多尔。提供了插图和物种的关键。先前不为人知的Palaestes和Thesaurus幼虫首次被描绘和描述。始新世的化石物种，Platisus punctatus (Ramirez, Corsolini & Di Iorio)，来自阿根廷巴塔哥尼亚，在这里被转移到同义龙属。本已发表的作品已在ZooBank注册。
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 (Ramirez, Corsolini & Di Iorio), from Patagonia, Argentina, is here transferred to the genus Thesaurus.This published work has been registered in ZooBank, .
