Coleopterans Adephaga Archostemata Polyphaga Bostrichiformia Cucujiformia Elateriformia Scarabaeiformia Staphyliniformia Coleopteran research • Liu et al. (2026) report the discovery of a specialized
Pachyteles-like beetle larva from the Cretaceous amber from Myanmar, with a morphology interpreted by the authors as suggestive of adaptations to ambush predation strategy and to
phragmotic defense. • Linhart et al. (2026) provide new information on the mouthpart morphology of
Partisaniferus edjarzembowskii, and interpret members of the genus
Partisaniferus as likely to be larvae of elateroid beetles with affinities with the families
Jurasaidae and
Cerophytidae. • Linhart et al. (2026) describe 45 new specimens of soldier beetle larvae from the Cretaceous amber from Myanmar and from the Eocene Baltic amber, and find no evidence of a significant loss of morphological diversity of larvae of members of this group throughout its evolutionary history. • Haug et al. (2026) identify a new morphotype of click beetle larvae from the Cretaceous amber from amber, characterized by long
setae on its body. • Li et al. (2026) revise the affinities of
Angimordella burmitina, interpreting it as more likely to be a member of
Apotomourinae than a relative of extant pollen-feeding specialists from the subfamily
Mordellinae, and interpret its interactions with contemporaneous flowering plants as more likely to be occasional rather than obligate. • Ferreira et al. (2026) provide new divergence time estimates for
bark beetles, and find that different dating methodologies all indicate that the group diversified before the
Cretaceous Terrestrial Revolution. • Rosas et al. (2026) report the discovery of a diverse assemblage of beetle fossils of probable Neogene age from a new site near the town of Penrose in the Southern Highlands (New South Wales, Australia). ==Clade Dictyoptera==
