Taxonomy edit

This species was first described by John S. Dugdale in 1971 using specimens collected at Station Point at the Snares Islands by Peter M. Johns.[2][3] In 2010 Robert J. B. Hoare discussed this species and gave a detailed description of the same.[4] The holotype specimen is held at the New Zealand Arthropod Collection.[2]

Description edit

Dugdale originally described the species as follows:

Adult fully winged; eyes not reduced; frons and vertex planoconvex, maxillary palpi minute, pollected, labial palpi with apical segment untufted at 12 length but with a band of black scales. Head, thorax, forewings grey, forewings with markings in brownish grey, viz.: an oblique mark on the costa basally, a 2nd at 13, connecting a diffuse blotch on the discal cell; another distinct spot at the apex of the discal cell; costal apex, and termen with an interrupted marginal series of black scales. Hindwings and abdomen dark grey. ♀︎ similar but generally more pallid. Antennae of ♂︎ setulose in whorls, setulae longer than segment width. Body length (vertex-wing tip) 8.5-9.5 mm (both sexes).[3]

Biology and behaviour edit

The larvae of this species are wood borers.[3][4] Adults are on wing from November to February.[4]

A host species of the larvae of this moth is Olearia lyallii.[3][4] Larvae have also been collected in bark of Brachyglottis stewartiae.[4]
