摘要
本研究描述了白垩纪中期缅甸琥珀中发现的百足目化石新属、新种 Acutiangulus densus Zhang, Liu & Yao gen.Acutiangulus densus Zhang, Liu & Yao gen. et sp. nov.与其他属种的区别在于肱骨角上有一个尖锐的棘刺，每个连接体的后外侧角上有一个刚毛棘刺。Acutiangulus densus是中生代 Centrocnemidinae 的第一个化石记录，也是茎类的一个成员。此外，位于冠状体内侧顶端的不规则梯形细胞被认为是百足虫科的辅助诊断特征。
The first report of fossil of Centrocnemidinae (Hemiptera: Heteroptera: Reduviidae) in the Mesozoic
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.
