Paramesopsocidae, a new Mesozoic psocid family (Insecta: Psocodea “Psocoptera”: Psocomorpha)

Abstract

Paramesopsocus lu n. gen., n. sp. and Paramesopsocus adibi n. sp. are respectively described from the Early Cretaceous amber of Lebanon and from the Late Jurassic limestone of Karatau (Kazakhstan). They are placed within the suborder Psocomorpha, and in the Mesozoic extinct family Paramesopsocidae n. fam. A cladistic phylogeny for Psocomorpha is given including our fossil taxa. The discovery of these new taxa demonstrates the necessity of a deep cladistic redefinition of the currently admitted major subdivisions of this suborder.
