蝽总科一新灭绝科--原蝽科。十一月，新发现4个新属和5个新种（Primipentatoma peregrina gen. et sp. nov.，方氏原五齿体线虫，新月短盾藻属和新种，新属和新种），描述了中国东北地区晚中生代沉积。化石和现存的形态特征相结合的基础上的支序分析澄清了新的家庭的系统发育地位，并允许重建内的超家庭Pentatomoidea的科间关系。系统发育分析的主要结论是：（1）该化石代表一个单系群，是除Saileriolidae + Urostylidididae外的所有蝽总科的姐妹群：（2）广义Urostylididae是一个并系群;（3）分析中高的bootstrap值支持了棘胸龙科、蝽科、甲蝽科和甲蝽科的单系性，但这些科之间的亲缘关系尚不清楚;（4）不支持Cydnidae的单系性。Pentatomoidea的起源时代应早于早白垩世（125-130 Ma），可能早于晚侏罗世或中侏罗世，起源中心在东亚。http://zoobank.org/urn:lsid:zoobank.org:pub:A432B387-E3A1-42D3-8051-867EB5108318
A new extinct family of Pentatomoidea, Primipentatomidae fam. nov., with four new genera and five new species (Primipentatoma peregrina gen. et sp. nov., Primipentatoma fangi gen. et sp. nov., Breviscutum lunatum gen. et sp. nov., Oropentatoma epichara gen. et sp. nov. and Quadrocoris radius gen. et sp. nov.), is described from the Upper Mesozoic deposits of north-eastern China. A cladistic analysis based on a combination of fossil and extant morphological characters clarifies the phylogenetic status of the new family and allows reconstruction of the interfamily relationships within the superfamily Pentatomoidea. Major conclusions of the phylogenetic analysis are: (1) the fossils represent a monophyletic group interpreted as the sister group to all Pentatomoidea exclusive of Saileriolidae + Urostylididae; (2) Urostylididae sensu lato is a paraphyletic group; (3) monophyly of Acanthosomatidae, Pentatomidae, Thyreocoridae, Dinidoridae, Phloeidae and Scutelleridae are strongly supported by high bootstrap values in the analysis, but the relationships among these families is less resolved; (4) monophyly of the Cydnidae was not supported. The time of origin of Pentatomoidea should be before the Early Cretaceous (125–130 Ma), and may be as early as the Late or Middle Jurassic with a centre of origin in East Asia. http://zoobank.org/urn:lsid:zoobank.org:pub:A432B387-E3A1-42D3-8051-867EB5108318
