Thank you. I did not mention Z. ogygia as, according to C&P4, the hindwing is unicolorous, whereas that of Z. ogygioides has 'the post-discal spots well marked'.
I had wondered about this key, as I have seen photos stated as Z. ogygia with these spots, but C&P4 is the best 'bible' I have!
Both species have the potential of being here.
