Dehiscensicoridae fam. nov. (Insecta: Heteroptera: Pentatomomorpha) from the Upper Mesozoic of Northeast China

摘要

A new family of insects is described from the Lower Cretaceous Yixian Formation in western Liaoning Province, China. Dehiscensicoridae Du, Yao & Ren fam. nov. comprises five new genera and five new species: Dehiscensicoris sanctus Du, Yao & Ren gen. et sp. nov., Pingquanicoris punctatus Du, Yao & Ren gen. et sp. nov., Changirostrus maculatus Du, Yao & Ren gen. et sp. nov., Crassiantenninus minutus Du, Yao & Ren gen. et sp. nov. and Minuticoris brunneus Du, Yao & Ren gen. et sp. nov. A cladistic analysis based on a combination of fossil and extant morphological characters is used to hypothesize the phylogenetic status of the new family, allowing the reconstruction of the interfamily relationships within the Coreoidea (sensu lato) which were found to be: Pyrrhocoroidea + (Dehiscensicoridae fam. nov. + (Coreoidea + (Idiostoloidea + Lygaeoidea))).
