Taxonomy

edit

This species was first described by Edward Meyrick in 1901 using material collected at Makatoku, in the Hawkes Bay, in March.[3] George Hudson discussed and illustrated this species both in his 1928 publication The Butterflies and Moths of New Zealand and his 1939 supplement to that work.[4][5] The lectotype specimen is held at the Natural History Museum, London.[2]
