Maoricrambus is a genus of moths of the family Crambidae. [2] It contains only one species, Maoricrambus oncobolus, which is endemic to New Zealand. This species is classified as Nationally Endangered by the Department of Conservation.

Taxonomy

M. oncobolus was named by Edward Meyrick in 1885 and described using a specimen collected at Castle Hill Basin, [4] [6] now part of the Kura Tāwhiti Conservation Area near Arthur's Pass. [7] In 1895 when listing the species George Hampson misspelt it resulting in the synonym for the species of Crambus oncolobus. [5] [8] In 1975 D. E. Gaskin erected the monotypic genus Maoricrambus for Crambus oncolobus. [9] The lectotype and paralectotype specimens are held at the Natural History Museum, London. [9]

Description

Meyrick described the species as follows:

Male, female. — 24-27 mm. Head white. Palpi very long, white, externally slightly ochreous-tinged. Antennas whitish, in male shortly ciliated. Thorax white or greyish-white, shoulders ochreous. Abdomen whitish-ochreous. Legs white, anterior pair internally fuscous. Forewings elongate, narrow, tolerably dilated, costa gently arched, apex round-pointed, hindmargin straight, oblique, strongly rounded beneath ; pale fuscous ; all veins suffused with white, more or less confluent towards costa posteriorly, and obscurely margined with dark fuscous ; a narrow white central streak from base to middle of disc, its apex sharply hooked downwards, margined beneath throughout by a strong black streak finely attenuated at base, and its apex margined posteriorly with black ; above the white central streak is a yellow-ochreous streak becoming dilated beyond it and suffused into ground- colour, and beneath the black streak a yellow-ochreous streak reaching apex of hook ; an ill-defined strongly dentate blackish posterior transverse line, tending to separate into longitudinal dashes, sharply angulated outwards above middle, and sinuate inwards towards inner margin : cilia pale greyish, suffusedly barred with white, tips white. Hindwings pale grey ; cilia whitish-grey. [6]

M. oncobolus is very similar in appearance to Orocrambus harpophorus . However M. oncobolus does not have the subterminal spotting of the forewings that can be found on the forewings of O. harpophorus. Also the two species are dissimilar in both the male and female genital structure. [9]

Adults are on wing from December to February. [9]

Distribution

M. oncobolus is endemic to New Zealand. [3] [10] This species is restricted to central Canterbury and Southland. [9] Specimens of this species have been collected at Porter River among the boulders and lichens near the edge of the river [11] and at the Sandy Point Domain near Invercargill. [12]

Habitat

M. oncobolus is associated with riverside grasslands in Southland and braided riverbeds central Canterbury. [13] [11]

Host plants

The host plants of this species are unknown. [13]

Conservation status

M. oncobolus is regarded as being "Nationally Endangered" under the New Zealand Threat Classification System. [1]

<i>Ichneutica steropastis</i> Species of moth endemic to New Zealand

Ichneutica steropastis, or the flax notcher moth, is a species of moth in the family Noctuidae. It is endemic to New Zealand and can be found throughout the country from the Three Kings Islands to Stewart Island as well as in the Chatham Islands. The larvae of this species feed on a variety of native and introduced plants however the New Zealand flax is one of the more well known host plants for the larvae of this moth. The larvae are nocturnal, hiding away in the base of the plants and coming out to feed at night. They create a distinctive notch in the leaf when they feed. The adults of this species are on the wing from October to March. Although adult specimens of I. steropastis are relatively easy to recognise they might possibly be confused with I. inscripta, I. theobroma or with darker forms of I. arotis. However I. steropastis can be distinguished as it has a long dark basal forewing streak that these three species lack.
