Diagnosis. Warrumiris viridis is recognised by the following combination of characters: body uniformly green to light brown, head, pronotum and scutellum greenish-brown, mesoscutum light brown; hemelytra green, membrane translucent and uniformly light smoky brown, with green veins infusing into adjacent areas; AI greenish-yellow ( Fig. 1 ). Genitalia as in genus diagnosis.

Description. COLOURATION. Dorsum mostly uniformly green to greenish-brown, often with speckled appearance, sometimes light brown; head and pronotum green to greenish-brown, posterior region of pronotum mostly darker, mesoscutum light brown, scutellum green to light brown. Hemelytra green, sometimes with green markings; inner margin of embolium and cuneus margins sometimes darker; membrane translucent and uniformly light smoky brown, veins green, infusing into adjacent area. AI light brown, sometimes tinged with green

speckling. Ventral surface greenish-yellow to yellow; propleuron sometimes green; abdomen rarely orangishyellow. Appendages greenish-yellow to yellow, sometimes with green speckling ( Fig. 1 ).

VESTITURE. See generic description.

STRUCTURE. Head transverse, 1.9x wider than long; First antennal segment 1.7x longer than interocular distance; second antennal segment approx. 1.5x longer than posterior margin of pronotum. Pronotum approx. 2.6x wider than long.

MALE GENITALIA. See generic description.

Measurements. See Table 1.

Plant hosts. One hundred and seventy-one specimens including both sexes of Warrumiris viridis were collected from species belonging to families Myrtaceae and Scrophulariaceae . Forty specimens, including both sexes were found on Eremophila mitchelli (Scrophulariaceae) . One hundred and twenty-three specimens, including both sexes, were collected from Eremophila sturtii (Scrophulariaceae) ( Table 2, Fig. 5 ). Eight specimens, including both sexes were collected from Eucalyptus populnea (Myrtaceae) , but are likely to be a sitting record.

Distribution. Warrumiris viridis is known from multiple, mostly inland locations in New South Wales, Northern Territory, Queensland and Western Australia ( Fig. 4 ).

Etymology. This species is named after its green body; from the Latin, viridis .

Remarks. See generic remarks.
