Another amber first: A tiny tetraphalerin beetle (Coleoptera: Archostemata) in Myanmar birmite

•First species of archaic beetle genus Tetraphalerus described in mid-Cretaceous amber from Myanmar.•First tetraphalerin beetle from Burmese amber named.•Fossil species of Tetraphalerus separated by 108 years from now relict species in South America.

A new tetraphalerin beetle, Tetraphalerus lindae sp. nov. (Insecta: Coleoptera: Archostemata) is described from mid-Cretaceous Burmese amber from northern Myanmar. This is the first species of this Jurassic-recent genus of archaic beetles to be described from amber inclusions, and is the first tetraphalerin cupedid from Burmese amber. This small, unusual Cretaceous Tetraphalerus is considered to belong to the T. bruchi species group of this now relict South American genus.
