[4][2] In 1885 Meyrick gave a detailed description of the species using specimens collected near Lake Wakatipu at 1,200 feet.

[5] George Hudson discussed and illustrated this species under the name Scoparia acompa in his 1928 book The butterflies and moths of New Zealand.

[2] The male holotype, collected at Lake Wakatipu, is held at the Natural History Museum, London.

Forewings triangular, costa gently arched, apex round-pointed, hindmargin almost straight, oblique; ochreous-fuscous; base irrorated with dark fuscous; first line very slender, obscure, whitish, posteriorly finely blackish-margined, not oblique, somewhat curved, sinuate inwards above inner margin; space between first and second lines fuscous, irrorated with dark fuscous, with a few pale scales; orbicular and claviform both round, ochreous-brown, obscurely blackish-margined, touching first line; reniform 8-shaped, white, suffusedly blackish-margined; second line very slender, obscure, whitish, anteriorly finely blackish-margined, rather abruptly curved above middle; subterminal obsolete; a slender interrupted white hindmarginal line : cilia ochreous-whitish, with two dark grey lines.

[5] However this species is very similar in appearance to Antiscopa epicomia but can be distinguished as A. acompa has a thicker antemedian forewing line.
