Introduction

This monotypic endemic genus was originally described as a member of the Membracidae (horned treehoppers) because of the large pronotal processes. It was transferred to the Cicadellidae by China (1924).

Diagnosis

Head large, porrect, quadrangular, superior surface nearly horizontal, lightly convex and furnished with a strong median longitudinal carina; ocelli below a line passing through centre of the prominent eyes, nearer to each other than to the eyes. Prothorax, for some distance from the base, convex, nearly horizontal, conforming to the base of the porrect head, after which it is broadened, vertical, and produced above each lateral angle in a large, triquetrous, conical, ear-shaped horn, which extends upward, outward and forward, the apex turned a little backward; the dorsum is very broad between these horns, and destitute of a median longitudinal carina; destitute of a posterior process, the posterior edge deeply and broadly sulcate forward. Scutellum as long as broad, the apex pointed, base rounded. Tegmina long, broad, reticulate with numerous venules; clavus very broad at base, gradually acuminate to apex, with two veins. Wings very large, nearly equal in size to the tegmina, with four apical cells, the tirst and third very long, the second shortest. Legs very long, femora slender, cylindrical and curved; tibiae slender, quadrilateral, the posterior pair with a row of denticles along the posterior edge; tarsi normal (Goding 1903).
