Beetles (Coleoptera) comprise about one quarter of all described animal species. One of the main contributors to their evolutionary success is the elytra, or hardened forewings, which have protective functions while maintaining their ability to fly. Unlike other beetles, some ship-timber beetles (Lymexylidae) have extremely small elytra and largely exposed functional hindwings. There is little fossil evidence illuminating the evolutionary history of short elytra in lymexylids. Here, I report fiv...

A leptochromine ant-like stone beetle, †Rovnoleptochromus balticussp. nov., is described, based on an exquisitely preserved inclusion in Upper Eocene Baltic amber from Kaliningrad Region. The holotype specimen reveals novel characters, not observed (presumably because of poorer preservation) in the previously known †R. ableptonoides Jaloszynski & Perkovsky of Rovno, Ukraine: three pairs of thick, long setae on the head (on vertex, near each eye and near each antennal insertion). Similar, presuma...

Abstract Three fossil species classified in the family Monotomidae are described from mid-Cretaceous Burmese amber. They are attributed to the recent tribe Lenacini Crowson, known so far from a single extant endemic species, Lenax mirandus Sharp, from New Zealand. Lenax karenae Liu, Tihelka, McElrath and Yamamoto sp. nov., Cretolenax carinatus Liu, Tihelka, McElrath and Yamamoto gen. et sp. nov., and Cretolenax diabolus Tihelka, Liu, McElrath and Yamamoto gen. et sp. nov. reveal high diversity a...

Fossil records of piestine rove beetles are very limited, with only two definite species from Mesozoic Chinese compressions, a single taxon from mid-Eocene Baltic amber and a doubtful Oligocene compression fossil from France. Here, a remarkable new genus and species, Propiestus archaicus gen. et sp. nov., is described based on a well-preserved individual in Upper Cretaceous Burmese amber from northern Myanmar (Cenomanian, c. 99 Ma). It represents the first piestine fossil found in Mesozoic amber...
