A world key to the genera of elcanidae (Insecta, orthoptera), with a jurassic new genus and species of archelcaninae from China

Abstract

A new fossil genus and species is described from the Middle Jurassic of China. The type of Sinoelcana minuta gen. et sp. nov. has body and legs preserved. It is distinguished from all other elcanids by the unique combination of wing venation and stout ovipositor. The sickle-shaped ovipositor suggests that the new species had a preference for oviposition on plant material. A world key to the genera of Elcanidae is provided based on the wing venation.
