Cretodascillus gen. nov. in the family Dascillidae with a new species C. sinensis sp. nov., is described from the Early Cretaceous Yixian Formation of Inner Mongolia, China. The fossil taxa described in Dascillidae have been critically reviewed and the Upper Triassic Apheloodes Dunstan, 1923 (type species A. obliquum Dunstan, 1923) and Leioodes Dunstan, 1923 (type species L. planum Dunstan, 1923) are removed from Dascillidae to Coleoptera incertae sedis, the Miocene Protoacnaeus Wickham, 1914 (type species P. tenuicornis Wickham, 1914) is transferred to Psephenidae and Miocyphon Wickham, 1914 (type species M. punctulatus Wickham, 1914) to Scirtidae.
