Aponotoreas orphnaea is a moth of the family Geometridae.

[4] Meyrick collected the type specimen of A. orphnaea in January of that year near the summit of Ben Lomond at 1700 metres.

[4] This moth subsequently became known as Notoreas orphnaea after Meyrick renamed the genus Pasithea as Notoreas when he became aware of that Pasithea was preoccupied.

[3] A. orphnaea has been observed in the high alpine zone of Central Otago in wetland habitat.

[8] It is regarded as being locally common on land covered by Mount Aspiring Station.
