[5] In 1928 Hudson, in his seminal work The butterflies and moths of New Zealand, discussed and illustrated this species again spelling the specific epithet orophyla.

[8][1] The male lectotype, collected at Lake Wakatipu, is held at the Natural History Museum, London.

The fore-wings of the male are pale brownish-grey; there is an obscure bent blackish line near the base, a moderately broad central band bounded by two very distinct shaded blackish lines, the basal one of which is not curved; the termen is shaded with darker grey, and there is an oblique pale mark near the apex.

The female is slightly darker than the male; and there are numerous wavy pale and dark grey lines filling up the entire wing on each side of the central band.[4]X.

orophyla can be found in the high country of the South Island and has been collected in Nelson, Canterbury, and Otago.
