I went mainly on the antennae. I think species specimens within O. antipoda seem quite variable so I would be hard put to pick a characteristic pattern.
The wing pattern is very unusual. To me it looks most like the western species O. occidentalis and O. perdita. I wonder if it could be a blow-in or a hybrid.
Fair comment, however In many cases the wing pattern cannot be relied on alone to distinguish Oxycanus species. O. sylvanus and O. antipoda are difficult to distinguish. We usually rely on the antennae to distinguish them (using Moths of Victoria's useful visual key as i did in this case) with O. antipoda having slightly longer peçtinations in the male antennae, particularly towards the base, than O. sylvanus. On second thoughts, looking at Moths in the ACT, I think I may have plumped for the wrong option, so I'll throw it open again for Don's consideration.
