Available Cretaceous inclusions of Dermestidae and the Jurassic impression fossil of Paradermestes jurassicus Deng, Ślipiński, Ren and Pang, 2017 were investigated, and their morphological characters were scored in the matrix along with all critical recent taxa. Phylogenetic parsimony analysis was used to evaluate the relationship of the fossils, leading to taxonomic changes. Cretodermestini Deng, Ślipiński, Ren and Pang, 2017, is raised to Cterodermestinae stat. nov. Nothattagenus Li and Cai, 2022 gen. rev. is removed from the synonymy of Ranolus Blair, 1929, and Attagenus secundus Deng, Ślipiński, Ren and Pang, 2017 is transferred to Nothattagenus as N. secundus (Deng, Ślipiński, Ren and Pang, 2017) comb. nov. The first Cretaceous species of Dermestes Linnaeus, D. lawrencei sp. nov., is described from Cretaceous Kachin amber. Aethriostoma turonianensis Perris and Háva, 2016, is removed from Attageninae to Megatominae and provisionally classified as Megatoma turonianensis (Perris and Háva, 2016) comb. nov.
