Abstract

Abstract: A rare species of archaic beetle, Paraodontomma szwedoi sp. nov., is described in burmite from northern Myanmar. It belongs to an unusual extinct genus with numerous pointed teeth along the edge of the body. It is the smallest species in the genus and reveals a dorsal ornamentation not previously reported. The beetle is undoubtedly an ommatine, a now relict family group in the southern hemisphere, but belongs to the extinct Brochocoleini when archaic beetles were more diverse in the Cretaceous tropics. Graphical abstract: Highlights: A new species of archaic beetle Paraodontomma szwedoi is described in mid-Cretaceous amber from Myanmar. It is an unusual and rare serrated beetle in the extinct tribe Brochocoleini. Paraodontomma was possibly adapted for a cryptic life on bark.
