disagree with that - the placement of the black forewing stigmata and the shape of the fasciae (especially the post-medial) is unlike any of those treated in the
Cyana guide in the link. There is a strong resemblance in the species to a female
Cyana guttifera, but without access to material for comparison, I am most reluctant to say it is
guttifera.
I have photos of a further two unidentified
Cyana species that remain problematic.

More observations required - i.e. need more people out recording to increase the recording effort to the point where these "rare" species are being observed with sufficient frequency to provide answers to the basic identification questions. Then it will be easier to answer the harder questions like "where, when, why (habitat and host associations)" that then allow questions about need for conservation to be addressed.
