Izatha voluptuosa is a species of moth in the family Oecophoridae. It is endemic to New Zealand. This species is classified as "Not Threatened" by the Department of Conservation.

Taxonomy and etymology[edit]

Watercolour by George Hudson, c. 1927

This species was described by Robert J. B. Hoare in 2010.[1] I. voluptuosa was first collected by George Hudson at Ohakune in January 1912.[2] However the species was misidentified.[2] Hudson illustrated the species in his 1928 book The butterflies & moths of New Zealand.[2][3] The holotype specimen is held at the Auckland War Memorial Museum.[4] This species is monophyletic, similar to other members of the Izatha genus such as I. attactella and I. blepharidota.[5] The epithet is obtained from the Latin word voluptuosus and refers to the large size and broad wings of the female of this species.[2]

Description[edit]

The larvae of I. voluptuose have yet to be described.[2]

The wingspan is 29–31 mm for males and 33–40 mm for females.[2] The female of this species has the greatest wingspan of gelechioid moths in New Zealand.[2] The species appears similar to I. attactella and I. blepharidota.[2] I. voluptuose can be distinguished from I. attactella as I. voluptuose has a wider forewing, has less conspicuous scale-tufts, and a shorter dark basal streak.[2] I. voluptuose is also generally on the wing later in the season and in the male of that species the hook-like teeth on the right lobe of the phallus are backward pointing.[2] I. voluptuose can be distinguished from I. blepharidota as the veins on the forewings of I. voluptuosa are similar to the colour of the rest of the wing.[2]

Distribution[edit]

It is endemic to New Zealand.[1] It is known from scattered localities in North Island in the following areas: Northland, Auckland, Bay of Plenty, Taranaki, Taupō and Rangitikei.[2]

Biology and behaviour[edit]

Adults are on wing from November to February with the moths being most prevalent in January and February.[2]

Host species and habitat[edit]

Larvae have been reared from rotten logs including those of Weinmannia racemosa.[2]

Conservation status[edit]

This species has been classified as being "Not Threatened" under the New Zealand Threat Classification System.[6]
