  Comment: Muir (1922) indicated that one of the type series, which he indicates is a paratype, is in the Australian Museum but does not indicate which specimen. Since Muir did not designate a holotype, no specimen has paratype status and all are regarded as syntypes.

Introduction

This largish, black cixiid has expanded forelegs interpreted by Muir (1922) as an indication that the nymph may be subterranean in habit. This possibility has yet to be confirmed. The profile of the expanded mesonotum with short narrow head gives a hump-backed appearance.
