New sinoalids (Insecta: Hemiptera: Cercopoidea) from Middle to Upper Jurassic strata at Daohugou, Inner Mongolia, China

Abstract

Fu, Y., & Huang, D., December 2018. New sinoalids (Insecta: Hemiptera: Cercopoidea) from Middle to Upper Jurassic strata at Daohugou, Inner Mongolia, China. Alcheringa 43, 246–256. ISSN 0311-5518.

A new fossil genus with three species of Sinoalidae, Parasinoala daohugouensis gen. et sp. nov., Parasinoala minuta gen. et sp. nov., Parasinoala magnus gen. et sp. nov., from the Middle to Upper Jurassic Haifanggou Formation at Daohugou, Inner Mongolia, northeastern China, is described and illustrated. The new genus differs from other sinoalids by the tegmen with RA having 2–3 branches, MP with 3–4 branches and MP of hind wings with two branches, which indicates the terminal branches of RA and MP are highly variable within Sinoalidae. The new discovery greatly increases the palaeodiversity of sinoalids in the early assemblage of the Yanliao biota from the Daohugou beds.
