Magnocoleus is an extinct genus of beetles from the
Early Cretaceous of
China, between 130.0 and 125.45 Mya.[1] The genus contains a single species, Magnocoleus huangjiapuensis, and is the only member of the family Magnocoleidae in the suborder
Archostemata.[2][3]Magnocoleus was first described by Chinese palaeoentomologist Hong Youchong in 1998, based on fossils of isolated elytra from the
Qingshila Formation in Huangjiapu, near the Nantianmen village of
Zhangjiakou in
Hebei.[2] Recent phylogenetic analyses have suggested that Magnocoleus is closely related to or placed within either
Cupedidae or
Ommatidae.[4]
