Abstract
A new genus and species of Sepulcidae, Yananphilius peizhuangensis gen. et sp. nov., are described and illustrated from the Middle Jurassic Yan’an Formation of Yan’an City, China. The taxon is erected based on a forewing with key diagnostic preserved. The new taxon is easily distinguishable from the other Parapamphiliinae because its long Sc vein reaches R slightly distad 1r-rs. This discovery demonstrates the overall stability of the Parapamphiliinae diagnosis, which remained unchanged for decades, and shows that its slight emendation allows for a better understanding of sepulcid wasps diversity during the Jurassic. This new species is the first Sepulcidae described in a Jurassic deposit from China and the Yan’an Formation.
