A new Middle Jurassic "grylloblattodean" family from China (Insecta: Juraperlidae fam. n.)

Abstract

The new family Juraperlidae is erected for the new genus and species Juraperla daohygouensis from the Chinese Middle Jurassic. Its wing venation has strong similarities with that of Mesozoic taxa currently included in the group "Grylloblattodea", but its character "three (or four?)-segmented tarsi" questions its potential inclusion into the same order with the modern Grylloblattodea. This suggests that the systematic assignments of several fossil "grylloblattid" species, mainly based on wing venation, could be very different.
