The species can be distinguished by the following features： the outermost branch of MP2 on the hind wing did not reach the margin of wing in Leptolingia calonervis sp. nov.;the second branch of Rs forked deeply while other branches of Rs forked much later in Litholingia ptesa sp. nov..展开更多

The genus Whalfera is considered as the only fossil genus confidently assigned to the Rhachiberothinae. Others previously placed in this subfamily belong to Paraberothinae （except perhaps for Oisea）. The Late Eocene/present Rhachiberothinae and the Cretaceous Paraberothinae are considered to be the subfamilies of Berothidae.展开更多

The new genus is assigned to the subfamily Paraberothinae. The new material confirms the great diversity of the group in the Cretaceous age and its decrease in diversity in recent times.展开更多

The well-preserved specimen was recovered from the Upper Jurassic Laiyang formation. It belongs to a rare specialized group within the Neuroptera because of the presence of distinctly different fore and hind wings in shape, size and venation. Based mainly on this character, a new family is erected, and its affinity and evolution are also discussed.展开更多
