Abstract

Tetratomidae is a small family of fungivorous beetles, comprising approximately 150 extant species in 13 genera and five subfamilies worldwide. Its fossil record is limited, with only seven named species from the Mesozoic and five from the Cenozoic. In the present study, the third species of the extinct eustrophine genus Allostrophus Hsiao, Ślipiński, Yu, Deng & Pang, 2018, A. tui sp. nov., is described from mid‐Cretaceous (Cenomanian, ca. 99 Ma) Kachin amber, northern Myanmar. The new species closely resembles A. cretaceus Hsiao, Ślipiński, Yu, Deng & Pang, 2018 in general appearance, but can be distinguished by its characteristic antennae, elytra, tibiae and tarsi. The discovery provides further data for completing the generic definition of Allostrophus and underscores the diversification of this small tenebrionoid family at both generic and species levels by the mid‐Cretaceous.
