  Type data:

   Holotype ANIC ♂ (coll.: 18-21.viii.1975, I.F.B. Common & M.S. Upton), Drysdale River, Western Australia [14°39'S 126°57'E].

Introduction

This beautifully marked species was added to the fauna by Fletcher (2002) who did not place it in a species group. It is clearly part of the roseicincta group based on the general shape of the head and tegmen and the bright colouring, particularly the green and orange longitudinal stripes on the mesonotum. It is only known from the Drysdale River in the North Kimberley region of Western Australia.

Diagnosis

Frons partly testaceous, heavily mottled with dark red, more heavily towards apical margin and lateral margins which are finely rimmed with black, becoming sordid brown ventrally. Vertex orange basally merging to red towards anterior and lateral margins with line of testaceous round spots around margins. Pronotum and mesonotum orange with median longitudinal stripe and lateral carinae broadly and percurrently green. Tegmen with longitudinal veins broadly orange-red, cells and costal margin pale testaceous, apical cells becoming dark red towards apical margin and granules of corium and clavus finely tipped with black. Frons about as wide as long to frontoclypeal suture. Lateral margins strongly carinate, almost foliaceous, apical margin percurrently carinate and medial longitudinal carina well developed throughout. Vertex wider than long (2.75 : 1), concave between carinate margins, slightly corrugated laterally. Anterior margin broadly and obtusely angulate. Hind margin concave. Pronotum anterior margin broadly convex, produced medially to align with hind margin of vertex. Lateral carinae well defined. Hind margin roundly and broadly V-shaped. Tegmen without, or with very obscure, cross venation in basal two thirds, including clavus. Sutural angle rounded, slightly more obtuse than right angle. Apical margin broadly rounded. Metatibial spine formula 1 : 6. Male anal segment elongate, apically flattened and broad. Pygofer with process elongate, apically slightly curved dorsally and clubbed. Subgenital plates narrow, parallel-sided, apically acute with dorsal process apically truncate-pointed, perpendicular to plate margin and remote from apex of plate (Fletcher 2002).
