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).

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
