Philpott described this species as follows:

♂. 12 mm. Head, palpi, abdomen and thorax dark purplish fuscous. Antennae purplish fuscous, ciliations in ♂ ½. Legs dark purplish fuscous, tarsi without annulations. Forewings with costa moderately arched, bent at ⅓, apex acute, termen extremely oblique; dark purplish fuscous sparsely sprinkled with white scales: fringes dark fuscous. Hindwings and fringes dark fuscous. [2]

This species can be distinguished from the similar appearing S. triatma as it has a much darker appearance and lacks the bluish-slate colour that can be seen on the fore-wings of S. triatma. [4]

Distribution

This species is endemic to New Zealand and has been observed in the lower parts of the South Island. [5] [4]

Behaviour

The adults of this species are day flying and on the wing in December. [4] [6]
