An extinct new family of Pentatomomorpha, Venicoridae Yao, Ren & Cai fam. nov., with 2 new genera and 2 new species (Venicoris solaris Yao, Ren & Rider gen. & sp. nov. and Clavaticoris zhengi Yao, Ren & Cai gen. & sp. nov.) are described from the Early Cretaceous Yixian Formation in Northeast China.
METHODOLOGY/PRINCIPAL FINDINGS: A cladistic analysis based on a combination of fossil and extant morphological characters clarified the phylogenetic status of the new family and has allowed the reconstruction of intersuperfamily and interfamily relationships within the Infraorder Pentatomomorpha. The fossil record and diversity of Pentatomomorpha during the Mesozoic is discussed.
CONCLUSIONS/SIGNIFICANCE: Pentatomomorpha is a monophyletic group; Aradoidea and the Trichophora are sister groups; these fossils belong to new family, treated as the sister group of remainder of Trichophora; Pentatomoidea is a monophyletic group; Piesmatidae should be separated as a superfamily, Piesmatoidea. Origin time of Pentatomomorpha should be tracked back to the Middle or Early Triassic.
本文描述了来自中国东北早白垩世义县组的已灭绝的新蝽类科,Venicoridae Yao, Ren & Cai fam. nov.,包括 2 个新属和 2 个新种(Venicoris solaris Yao, Ren & Rider gen. & sp. nov. 和 Clavaticoris zhengi Yao, Ren & Cai gen. & sp. nov.)。
方法/主要发现:基于化石和现存形态特征的系统发育分析阐明了新科的系统发育地位,并重建了亚目内和科内的超科和科际关系。讨论了中生代蝽类的化石记录和多样性。
结论/意义:蝽类是一个单系群;Aradoidea 和 Trichophora 是姊妹群;这些化石属于新科,被视为 Trichophora 其余部分的姊妹群;Pentatomoidea 是一个单系群;Piesmatidae 应作为一个超科,Piesmatoidea 分离出来。蝽类的起源时间应该追溯到中三叠世或早三叠世。
