This species was first described by Edward Meyrick in 1914 using three specimens collected in August in Karori by George Hudson.

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

Forewings elongate, narrow towards base, hardly dilated, costa gently arched, apex tolerably pointed, termen nearly straight, very oblique; fuscous, mixed with grey in disc; dorsum suffused with pale ochreous towards base, edged by a blackish raised dot at 1⁄5 of wing; stigmata undefined, pale ochreous, plical nearly beneath first discal : cilia fuscous sprinkled with whitish-ochreous, base spinkled with blackish.

Forewings ovate-lanceolate; fuscous suffusedly mixed with darker, especially towards base; dorsal area suffused with whitish-ochreous towards base; second discal stigma represented by a raised ochreous tuft edged with dark fuscous.

[3] Both the female and the male of the species can be found on cold nights resting on fences.
