This is the only member of the Membracidae which we found in Guam. It is commonly called the "Carnbao bug" on account of its lateral thoracic horns. It is generally distributed and occurs on many kinds of trees and plants, but not numerous enough to be rated as a pest. W. D. Funkhouser has kindly verified my identification.

This insect is widely distributed in India, Ceylon, Borneo, Timor, and the Philippines. It was not previously recorded from Guam, though collected by Fullaway in 1911.
