本文重新描述华南和新疆上三叠统和下侏罗统20枚甲虫模式标本,共识别出Cupedidae科3属5种,Elateridae科4属4种,Permosynidae科4属5种,Schizocoleidae科2属3种,未定科3属3种。将Notocupoides知sciatusPonomarenko,1966归入Notocupes,建立一新种Notocupeslinisp.nov.;基于Ademosynoides chinaticusLin,1992建立一新属Toksuniusgen.nov.,形成一新组合Toksunius chinaticus(Lin,1922)comb.nov。
Twenty type specimens of beetles from the Upper Triassic and Lower Jurassic of southern China and Xinjiang are re-examined in detail: five species within three genera are assigned to Cupedidae, four species in four genera assigned to Elateridae five species in four genera are assigned to Permosynidae, three species in two genera are assigned to Schizocoleidae three species in three genera are incertae familiae. A new species, Notocupes lini sp. nov. is proposed for Notocupoides fasciatus Ponomarenko, 1966. A new genus, Toksunius gen. nov. , is proposed for Ademosynoides chinaticus Lin, 1992, resulting in Toksunius chinaticus (Lin, 1922) comb. nov.
