摘要

A new extinct family of Pentatomoidea, Primipentatomidae fam. nov., with four new genera and five new species (Primipen-tatoma peregrina gen. et sp. nov, Primipentatoma fangi gen. et sp. nov, Breviscutum lunatum gen. et sp. nov, Oropentatoma epichara gen. et sp. nov. and Quadrocoris radius gen. et sp. nov), is described from the Upper Mesozoic deposits of north-eastern China. A cladistic analysis based on a combination of fossil and extant morphological characters clarifies the phylogenetic status of the new family and allows reconstruction of the interfamily relationships within the superfamily Pentatomoidea. Major conclusions of the phylogenetic analysis are: (1) the fossils represent a monophyletic group interpreted as the sister group to all Pentatomoidea exclusive of Saileriolidae + Urostylididae; (2) Urostylididae sensu lato is a paraphyletic group; (3) monophyly of Acanthosomatidae, Pentatomidae, Thyreocoridae, Dinidoridae, Phloeidae and Scutelleridae are strongly supported by high bootstrap values in the analysis, but the relationships among these families is less resolved; (4) monophyly of the Cydnidae was not supported. The time of origin of Pentatomoidea should be before the Early Cretaceous (125-130 Ma), and may be as early as the Late or Middle Jurassic with a centre of origin in East Asia.
