Abstract

The relict family Ommatidae belongs, among other reticulated beetles (suborder Archostemata), to one of the most basal lineages of Coleoptera. Ommatids were much more diverse during the Jurassic and Cretaceous when the family attained a global distribution. Here we report two new species from mid-Cretaceous Burmese amber, Stegocoleus arkonus sp. nov. and S. lawrencei sp. nov. A key to the extinct beetle genus Stegocoleus is provided. The characteristically wide epipleural rims of Stegocoleus and the pronounced surface carinae probably served a protective function against potential predators.
