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

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 sanctusDu, Yao & Ren gen. et sp. nov.,Pingquanicoris punctatusDu, Yao & Ren gen. et sp. nov.,Changirostrus maculatusDu, Yao & Ren gen. et sp. nov.,Crassiantenninus minutusDu, Yao & Ren gen. et sp. nov. andMinuticoris brunneusDu, 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))). http://zoobank.org/urn:lsid:zoobank.org:pub:E501B670-AF36-408C-8B9D-466B330BA775 [ABSTRACT FROM PUBLISHER]
