A new ommatin beetle (Insecta: Coleoptera) with unusual genitalia from mid-Cretaceous Burmese amber

A new ommatin beetle, Omma lii sp. nov. (Insecta: Coleoptera: Archostemata) is described in mid-Cretaceous Burmese amber from northern Myanmar. This is the first species of this Late Triassic-recent genus of archaic beetles to be described from amber inclusions, including genitalia, and is the first unequivocal ommatine cupedid from Burmese amber. Cretaceous Omma is considered to belong to the stem group of this now relict Australian genus.
