Abstract

Novalyda cretacica , new genus and new species (“Symphyta”: Pamphilioidea: Xyelydidae), is described based on a unique male from the Early Cretaceous, Yixian Formation of northeastern China. The new species differs from others in the family by its relatively thick antenna, narrow costal cell, short first abscissa of Rs, sclerotization of the pterostigma. The species is the youngest occurrence of the family and extends the lineage into the Cretaceous period.
