Abstract

Three new genera and six new species of fossil elaterids of the tribe Desmatini Dolin, 1975 from second Bed of the Upper Jurassic-Lower Cretaceous Yixian Formation in Huangbanjigou, Liaoning Province, China are described: Paradesmatus dilatatus sp. nov., Desmatinus cognatus gen. et sp. nov., Apoclion clavatus gen. et sp. nov., A. dolini gen. et sp. nov., A. antennatus gen. et sp. nov. and Anoixis complanus, gen. et sp. nov. This tribe demonstrates some characters similar to those in Throscidae and Eucnemidae, elucidating the evolutionary process of the Elateroidea. New materials make clear the distinctness of the genera related to Desmatus Dolin, 1975 (tribe Desmatini) from all other Elateridae. Tetraraphes ebersini Iablokoff-Khnzorian, 1961 could be regarded somewhat nearby the subfamily Protagrypninae; however, this species seems to be similar to some Cenozoic groups rather than any of Mesozoic groups.
