This species was first described by Edward Meyrick in 1913 using a male specimen collected at Ohakune by George Hudson.

[3] Hudson discussed and illustrated this species in his 1928 book The Butterflies and Moths of New Zealand.

[5] The male holotype specimen is held at the Natural History Museum, London.

Forewings elongate, somewhat dilated posteriorly, costa moderately arched, apex obtuse, termen very obliquely rounded; whitish-ochreous, somewhat sprinkled with fuscous and dark fuscous; a suffused dark-fuscous streak running from base of costa to plical stigma; stigmata large, dark fuscous, pale-centred, especially second discal, plical obliquely beyond first discal; a spot of dark-fuscous suffusion on costa above second discal stigma, and a larger spot on costa at ¾, whence an indistinct angulated dark-fuscous line runs to dorsum before tornus: cilia whitish-ochreous, on upper half of termen spotted with fuscous at base.

[1] As well as being observed at its type locality of Ohakune, it has been recorded at Mount Ruapehu, Tongariro, Saint Arnaud.
