Introduction

This species is found on branches of broad phyllodinous Acacia (Fabaceae) shrubs from SE Queensland to the Sydney region. In dorsal view, it is dark with a small white mark towards the apex of the forewing but ventrally the female abdomen is bright green and the face of the head is also brightly coloured, either greenish yellow or bright red. Constant (2006) included some photographs of live adults and nymphs taken by Mr Peter Chew of Brisbane.

LT: ♂ (n = 9): 9.6 mm (8.9 to 10.9); ♀ (n = 10): 10.0 mm (9.0 to 10.8). Head: frons, vertex and basal 1/2 of clypeus greenish yellow to bright red; apical 1/2 of clypeus, labium and often posterior 1/2 of vertex brown; ratio BV/LV = 3.5 - 4.6; BF/LF = 2.1 - 2.2. Thorax: brown; ratio LP+LM/BT = 0.78 - 0.80. Tegmina: brown, darker on costal 1/3; short, transverse, white line at apico-costal angle; often short, transverse white line at apico-sutural angle, always narrower than apico-costal line; ratio LTg/BTg = 2.17 - 2.22. Hind wings: uniformly blackish brown. Legs: all legs brown; tibiae I and II roundly truncate apically. Abdomen: bluish green dorsally, yellowish ventrally. Genitalia ♂: pygofer about as high as long basally, constricted in middle in lateral view; gonostyli fused ventrally on basal 2/3, convex, produced dorsally at apex, with strong, dorso-anterior impression and curved process at dorso-anterior angle; anal tube dorso-ventrally flattened, elongate, rounded apically, lateral margins subparallel on apical 2/3.
