Introduction
Protelytroptera were diverse during the Permian. The fore wings of these insects were hardened and often convex, resembling the elytra of beetles. However, other features of their morphology point to a close relationship with orthopteroid insects.
Carpenter (1992) claims that the Cretaceous Umenocoleus is a protelytropteran, but other authors believe it to be a beetle (Chen & Tan 1973, Tan 1991).
