First record of Sinoxytelus (Coleoptera: Staphylinidae) from the Urey locality of Transbaikalia, Russia, with discussion on its systematic position

A new rove beetle species, Sinoxytelus transbaicalicus sp. nov., is described and figured from the Urey locality (Urey beds, Early Cretaceous?), Transbaikalia, Russia. Sinoxytelus is the dominant genus in the Early Cretaceous Yixian Formation of northeastern China, but this is the first report from the territory of Russia. The new species can be easily separated from the rest of its congeners by the presence of a relatively large head, transverse pronotum, and slightly tapered abdomen. In addition, the systematic position of Sinoxytelus in the extant subfamily Oxytelinae is discussed. Sinoxytelus is transferred from the tribe Oxytelini to the more basal tribe Coprophilini.
