Mesokristensenia differs from all extant Lepidoptera, but one genus (Agathiphaga, Agathiphagidae), in retaining four median veins in the forewing, a plesiomorphy also present in many Trichoptera. Evidence for placing Mesokristensenia in the Lepidoptera includes four traits, notably a previously unrecorded autapomorphy of this insect order: beyond stem Ml+2, vein M1 is bent and connected to cross-vein r-m (in both wing pairs). Among 24 characters taken into account to assess the systematic position of Mesokristensenia, 12 are considered informative for a cladistic analysis involving this fossil taxon and the four suborders recognized in present-day Lepidoptera (Zeugloptera, Aglossata, Heterobathmiina, and Glossata).展开更多

We report herein the first discovery of an empheriid psocid from the Cretaceous amber of New Jersey as Jerseyempheria grimaldii gen. et sp. nov. The fossil is figured and described. The new species is distinguished from related taxa. A discussion and checklist of Empheriidae are provided.展开更多
