Abstract
A pygmy dormouse Typhlomys stegodontis sp. nov. is described on the base of the maxillary fragment and isolated teeth from the Middle Pleistocene Tham Hai cave locality in northern Vietnam (Lang Son Province). This first finding of the fossil Platacanthomyidae in Vietnam fills the Middle Pleistocene gap in the paleontological record of the family.
