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 &amp; Ren fam. nov. comprises five new genera and five new species: <i>Dehiscensicoris sanctus</i> Du, Yao &amp; Ren gen. et sp. nov., <i>Pingquanicoris punctatus</i> Du, Yao &amp; Ren gen. et sp. nov., <i>Changirostrus maculatus</i> Du, Yao &amp; Ren gen. et sp. nov., <i>Crassiantenninus minutus</i> Du, Yao &amp; Ren gen. et sp. nov. and <i>Minuticoris brunneus</i> Du, Yao &amp; 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 (<i>sensu lato</i>) 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
