This species was first described by Alfred Phipott in 1927 using specimens collected by himself and Stewart Lindsay at Arthur's Pass in February.[2][3] The holotype specimen is held in the Canterbury Museum.[4]

Description edit

Philpott originally described this species as follows:

♂. 11.5 mm. Head ochreous-whitewith medium brown stripe. Palpi white. Antennae greyish-fuscous. Thorax white, tegulae and medium stripe fuscous. Abdomen white mixed with fuscous. Legs ochreous-white mixed with fuscous. Forewings, costa almost straight, apex acute, termen extremely oblique; white; base of costa to 16 narrowly fuscous; a whitish-ochreous stripe along costa, broadest on basal 12 ; an ochreous stripe along fold to 25 ; an ochreous-fuscous stripe above fold, commencing about 13 and running to apex, where it becomes slightly dilated and blackish; a fuscous stripe along dorsum to tornus, thence continuing, but much paler, half way to apex; fringes pale ochreous-fuscous with black basal line round apex. Hindwings dark fuscous; fringes pale ochreous-fuscous.[2]

This species is similar in appearance to Elachista thallophora but differs in how the stripes are arranged on the forewings.[2]
