A new species of “Orthophlebiidae” (Insecta: Mecoptera) from the Middle Jurassic of Inner Mongolia, China

Abstract

A new species of “Orthophlebiidae”, Orthophlebia riccardii n. sp., is described from the Middle Jurassic of Inner Mongolia, China. Males of the genus have the last segments of the abdomen enlarged and modified with spurs and projections ending in clamp like dististyli. The new species can be distinguished from all known species by its bigger size and the presence of a distinct organization of the abdomen of the male.
