This moth is one of the earliest to emerge in the New Zealand spring with adults being observed from August to December.

[4][2] He used two specimens collected in December in the Waitākere Ranges beaten from a small leaved shrub in Kauri forest.

[5][6] In 2010 the Inventory of New Zealand Biodiversity listed this species under the name Holocola parthenia.

Forewings elongate, costa moderately arched, apex round-pointed, hindmargin sinuate, rather strongly oblique; light brownish-ochreous, tinged with grey towards inner margin; a broad white streak along costa from base to apex, extremities pointed, margined beneath by a blackish streak from before middle to apex; about eight fine short dark fuscous strigulae on posterior half of costa; an erect leaden-metallic streak from anal angle, and another from middle of hindmargin, both touching margin of costal streak : cilia pale brownish-ochreous, with a blackish apical spot.

[1] As well as its type locality of the Waitākere Ranges in the Auckland Region, it has also been observed in Whangārei, Wellington and in Southland.
