Introduction

This unusual, and immediately identifiable, endemic membracid is most common in the rainforests of Queensland although it extends as far south as the Australian Capital Territory. The shape of the single dorsal projection on the pronotum is highly variable and Day (1999) has suggested that this requires research to determine if more than one species is represented in the fauna. There are plenty of available names which may be applicable for cryptic species if they are found to exist.

Diagnosis

Piceus, pubescens; prothorax robustus ; cornu dorsale crassum, erectum, testaceo notatum, postice gibbosum, lateribus productis acutis; cornu posticum gracile, carinatum, acutum, valde arcuatum, basi albidum, abdomen paullo superans; abdomen ferrugineum; pedes ferruginei, femoribus nigris, tibiis latiusculis; alae anticae fasciis duabus guttularibus albidis; posticae subcinereae.
Piceous, pubescent. Prothorax thick, slightly keeled in front, armed between the somewhat acute shoulders with a thick erect horn, the tip of which has some testaceous marks and is gibbose hindward, and is dilated on each side into an acute horn; the prothorax is gibbose behind this horn, and the hind horn is slender, keeled, acute, much curved, whitish towards the base, and extends a little beyond the abdomen. Abdomen and legs ferruginous. Femora black, with ferruginous tips; tibiae rather broad. Fore wings with two bands of whitish dots. Hind wings grayish. Length of the body 2 lines; of the wings 4 lines (Walker 1858).
