Don, this from Ethan Beaver: “That looks like what is currently known as Clania ignobilis. That species has a cryptic east coast species which is genetically different from the rest of Australia, so may in future be referred by a different name. Either way, both populations of C. ignobilis are generally distinguished from lewinii by the absence of distinctive black and white longitudinal stripes on the thorax, additionally, ignobilis mainly has wings of one colour while in lewinii they are partially hyaline and have vague, alternating patterns that are almost variegated in appearance”
There is some striping, but no distinctive white complementary shoulder patch on the thorax either side. which also seems to be characteric of C. lewinni. There are several C. ignobolis with some striping present on the ALA which do look very similar to this specimen.
