The recdntly published Part 9 of Moths of Victoria (MoV) provides a guideline: 'Comparison of P. hypochalchis and P. tibiata' on the supporting disc to the Part at page 3/4 for P. hypochalchis. For P. hypochalchis this guideline says that species has a reniform mark which is a 'broad, dark bar, slightly cuved)' whereas the corresponding reniform mark for P. tibiata is a 'broad, dark 'horseshoé enclosing an orange patch'. Moreover, the underside of the wings are úniformly dark'. The second photo of this speciemen shows this clealry and the descriptions and the images on the supporting disc matches this speciimen closely. PS On this basis , I asked michaleb (thank you Michael) to suggest this change for me because I found the CNP system did not allow me to make this suggestion as a moderator directly as I normally would.

Ian has covered how to distinguish the males of the two species, and this is a male. The two species are sexually dimorphic, and MoV also describes how to separate the females. The reniforms and the base colours are different. The undersides are similar in the two species, and quite different to both males.
