I just looked at ones I have previously put on iNat (found in SEQ) and as you noted, this one is a bit different. I thought the ring of the eyespot was very black. I checked my other photos from tonight and they are all the same so it isn't photo angle or lighting.
No i don't think so, Antheraea eucalypti was the prior name I believe. See here from the ALA: This species was formerly placed in the genus Antheraea."" Opodiphthera eucalypti date from a 2010 revision. Thet are synonyms (AFD).
