New data on Jurassic Procercopidae (Hemiptera: Cercopoidea) from northeastern China

Abstract

Two close species of the extinct family Procercopidae, Procercopina lini sp. nov., and Procercopina daohugouensis sp. nov., are described and illustrated from the Middle–Upper Jurassic Daohugou beds, Inner Mongolia, northeastern China. Procercopina Martynov, 1937 as one of the early representative of procercopids, includes five species confined to the Lower Jurassic of Eurasia. The taxonomic position of Procercopina within Procercopidae and its relationship with other genera are discussed. The new discovery represents the latest record of Procercopina and the first record in Yanliao biota of northeastern China, indicating this genus is widely distributed in Eurasia during the Jurassic. P. lini represents the first whole‐bodied fossil among Procercopina, providing valuable information of the morphological features of this genus.
