Introduction

This species is only known from four specimens from the wet tropics of North Queensland. The known specimens all have distinctive brown markings and a broad reddish brown border around the tegmen. It was placed in the anomala Group by Fletcher (1985) primarily on features of the male genitalia.

Diagnosis

This species was placed by Fletcher (1985) into the anomala group but, although the five species in this group show affinity with each other, they lack uniform characteristics throughout.
Green fading to yellow. Head with red along margins and carinae. Mesonotum with two red marks posteriorly. Tegmen with broad red to red-brown margin extending from near base of costal margin around apical margin and claval margin to apex of clavus, interrupted at vein endings. Tegminal disc with dark granules surrounded by broad brown areas so that tegmen has spotted appearance. Clavus with outer cell entirely or mostly brown in colour. Head with vertex short with front margin obtusely angulate; frons with three carinae extending over at least 2/3 length of frons. Tegmen with apical angle rounded; sutural angle right-angled; M1+2 branched about level with apex of clavus. Male pygofer with short blunt process curving slightly ventrally. Paramere with elongate process at about 2/3 length of dorsal margin. Female third valvulae broad at base with narrow triangular lobes posteriorly. Second valvulae gap wide with apex of valvulae incurving distally (Fletcher 1985).
