   Centrotus decisus Walker, 1851 by original designation.

Introduction

This is one of the largest genera of Membracidae in Australia with ten species. The species are mostly large, robust and dark brown with solid pronotal processes. They appear to be associated with the genus Eucalyptus l'Héritier (Myrtaceae). The presence of the genus in Papua New Guinea was suggested by Day (1999) although this has yet to be confirmed.

Diagnosis

Pronotum with the lateral processes broad, compressed, their broad upper surfaces with several longitudinal strong carinations, more or less subobliquely produced, and more or less broadly apically truncate, the posterior process long, more or less compressed, and broad on its basal area, its lateral areas usually distinctly carinate, its apical area more or less convexly impinging on tegmina, which are about twice or a little more than twice as broad as long, the apical cells elongate and five in number, preceded by two discoidal cells (Distant 1916).

Large robust species with long, narrow apical cells. Conspicuous ocelli as close or closer to each other than to eyes. Veins M and Cu separate, M–cu1 present. Lateral pronotal processes strongly developed, median pronotal process long, terminating at or almost at apex of tegmen. Pronotal notch weakly developed. Tibiae flattened. Cucullate setae on hind tibiae either absent or in one or two rows (Day 1999).

Day (1999) provided a comprehensive redescription of the genus.
