This species was first described by John Salmon in 1948 using a specimen collected by Graham Turbott on 22 April 1946 on Great Island at the Three Kings Islands.[2][3] The family level classification of this endemic moth is regarded as unsatisfactory, and it is not correctly placed in the genus Lysiphragma.[3] As such the species is currently also known as Lysiphragma (s.l.) argentaria.[1][4] The holotype specimen is held at the Auckland War Memorial Museum.[3][5]
Description
Salmon described this species as follows:
The expansion of the wings is 12 mm. The general colour is silvery white on the forewings and head; pale grey on the thorax; with patagia whitish; pale-ochreous white on the abdomen and silvery-grey on the hind wings, with strong metallic reflections. The forewings are clouded with scattered grey scales along the costa from the base to about three-quarters; there is an apical cloudy-grey patch and a similar sub-apical patch on the tornus; basal streak marked by a line of yellowish-orange terminated by two or three very dark-brown scales. Cilia of the forewings pale-brown, of the hind wings silvery-grey. The costa of the forewings is gently arched, the dorsum almost straight, the apex rounded and acute. Antennae dark-brown banded with white; palpi brown shaded with white. Head and thorax heavily scaled. Legs greyish-white.[2]
Distribution
This species is endemic to New Zealand.[1][4] It is only found on the Three Kings Islands.[6]
Biology and behaviour
Much of the biology of this species is unknown.[6] This species is attracted to light.[2] Adults of this species are on the wing in April.[5]
Host species and habitat
The holotype specimen was collected on a "tea tree".[5]
