Mesozoic Centrocnemidinae Burmese amber taxonomy new genus Hemiptera Heteroptera Reduviidae

Abstract

A new genus and species of fossil of Centrocnemidinae, Acutiangulus densus Zhang, Liu & Yao gen. et sp. nov., is described and illustrated from mid-Cretaceous Burmese amber. Acutiangulus densus Zhang, Liu & Yao gen. et sp. nov. can be distinguished from other genera by the humeral angle with a sharp spine and the posterior lateral angle of each connexival tergite with a setigerous spine. Acutiangulus densus is the first fossil record of Centrocnemidinae from Mesozoic and also represents a member of the stem group. Furthermore, the irregular trapezoidal cell situated in the corium’s inner apical is proposed to serve as an adjunctive diagnostic character for Centrocnemidinae.
