Jarzembowski, E.A. & Wang, B., February 2016. An unusual basal beetle from Myanmar (Coleoptera: Archostemata). Alcheringa 40, XX-XX. ISSN 0311-5518A new archostematan beetle, Stegocoleus caii gen. et sp. nov. (Insecta: Coleoptera) is described from mid-Cretaceous Burmese amber from northern Myanmar. This is the first basal beetle to be formally described from this deposit. It shows a unique combination of family characters and is provisionally referred to Cupedidae in the broad sense and possibly subfamily Ommatinae. The dorsal ornamentation and expanded elytra with window punctures make it a very distinctive albeit rare insect in this rich amber biota. Some of the challenges in studying the inclusions in this amber deposit include their diminutive size, difficulty in preparation and deformation.
