Jurassic and Cretaceous Cupedomorpha (Insecta: Coleoptera) faunas of China

摘要

Widespread non-marine Mesozoic deposits in China often contain abundant cupedomorpha fossils with significance for correlation. Based on the composition and characteristics of the cupedomorphs, at present, seven cupedid and ommatid assemblages are recognized from the Jurassic-Cretaceous rocks, of which three cupedid and two ommatid assemblages were recovered from North and northeast China: Middle Jurassic Tetrocupes-Hebeicupes cupedid assemblage from northern Hebei and Inner Mongolia (Yanliao fauna); Late Jurassic or Early Cretaceous Ovatocupes-Priacma cupedid and Amblomma-Sinocupes ommatid assemblages from western Liaoning (Jehol fauna); Early Cretaceous Lupicupes-Diluticupes cupedid and Monticupes ommatid assemblages from Beijing and adjacent areas. Both the Ovatocupes-Priacma and Amblomma-Sinocupes assemblages are important elements of the Jehol entomofauna. Remaining are the Late Jurassic or Early Cretaceous Mesotricupes-Gansucupes cupedid assemblage from Jiuquan Basin, Gansu Province, NW China and the Forticupes-Picticupes ommatid assemblage from Shandong Province. In southern China only one poorly preserved ommatid specimen, Zygadenia ( = Notocupes) sp. occurs.
