Taxonomy

This species was first described by Alfred Philpott in 1903 using male specimens collected at West Plains, Invercargill. The male holotype has been lost but the two male paratype specimens are held in the New Zealand Arthropod Collection.

The female of this species have wings that are reduced in size.

This species has been observed in the North, South and Stewart Islands, including in the Tararua Range, at Mount Arthur, Arthur's Pass, Otira, Dunedin and Invercargill in the South Island. In the North Island and the northern parts of the South Island this species appears to inhabit sub-alpine forest glades. However further south in the southern parts of the South Island and on Stewart Island this species can be found in lowland habitat.

The adults of this species are on the wing from October to February. The adult moths are attracted to light.
