Zapyrastra stellata

Zapyrastra stellata is a species of moth of the family Momphidae first described by Alfred Philpott in 1931. It is endemic to New Zealand and has been observed in Otago. The larvae of this species mine the leaves of Meuhlenbeckia. Adults are on the wing in June and December.

Taxonomy
This species was first described by Alfred Philpott in 1931 using a specimen collected by Charles E. Clarke in Wānaka (previously known as Pembroke) in December. In 1988 J. S. Dugdale placed this species within the genus Zapyrastra. The male holotype specimen is held at the Auckland War Memorial Museum. In 2019 Lauri Kaila placed this species in the genus Mompha stating "Current status: Mompha (as Zapyrastra) stellata (Philpott, 1931) (Momphidae); Dugdale (1988)".

Description
This species was described by Philpott as follows: "♂. 7.5 mm. Head, antennae, thorax and abdomen bronzy brown. Palpi bronzy brown mixed with whitish. Legs bronzy brown, tibial spines on posterior pair white. Forewings with costa subsinuate, apex rounded, termen very oblique; bronzy brown; a large snow-white spot on costa at $5/6$ reaching halfway across wing: fringes fuscous grey. Hindwings and fringes greyish fuscous."

This species can be distinguished from other species with a similar appearance as it has a prominent white costal patch.
