Quick Summary

The suborder Coleorrhyncha is a group of insects within the order Homoptera. These insects are characterized by their beak originating at the antero-ventral extremity of the face, which is sheathed by propleura. They lack hind wings, and their forewings are held flat over the abdomen when at rest, rendering them incapable of flight. The prothorax has paranota, and their digestive tract does not possess a filter chamber. The most primitive members of the Homoptera, the family Pelorididae, belong to this suborder and are found in Tasmania, New Zealand, and South America.1
