Glaresis burmitica sp. nov., the first amber inclusion of Glaresidae is described and figured based on a well preserved adult from the Upper Cretaceous Burmese amber. Glaresis burmitica differs from all extant and extinct congeners by its small body size, non-grooved pronotum, teeth on protibial outer margin, and unmodified outer margins of meso- and metatibia. The discovery of Glaresis burmitica from the Late Cretaceous suggests that the extant genus Glaresis is an ancient lineage, and its external morphologies changed very little through a long geological time. Together with previous findings in the Lower Cretaceous of northeastern China, it also highlights the palaeodiversity of the peculiar family Glaresidae.
