This species was described by Edward Meyrick in 1885 using a specimen he collected at Otira Gorge at an altitude of 1,600 ft in January.

[6][7] George Hudson, in his 1928 publication The Butterflies and Moths of New Zealand, followed Meyrick and discussed this species as a synonym of Carposina gonosemana.

[2] The female holotype specimen is held at the Natural History Museum, London.

Palpi rather long, lower half dark fuscous, upper white.

Forewings elongate, narrow, oblong, costa moderately arched, somewhat bent at 1⁄3, apex round-pointed, hindmargin slightly sinuate, rather strongly oblique; very pale grey, irrorated with white towards costa and hindmargin, and with scattered dark fuscous scales; a blackish elongate spot along costa at base; a blackish dot above inner margin near base; costa with six small fuscous spots between 1⁄3 and apex; discal and posterior tufts also preceded by small obscure fuscous spots : cilia pale grey mixed with whitish.
