Mnesarchaeoidea is a superfamily of "New Zealand primitive moths" containing one family, Mnesarchaeidae, and a two genera, Mnesarchaea and Mnesarchella, both of which are endemic to New Zealand.
Mnesarchella acuta is a species of primitive moths in the family Mnesarchaeidae. It was described by Alfred Philpott in 1929, and is endemic to New Zealand. It is found in the Rangitikei, Wellington, Marlborough Sounds, Nelson, Buller, Westland, Kaikōura and north Canterbury regions. It is very similar in appearance to M. hamadelpha. This species lives in a variety of damp habitats in forests or near waterways that are not exposed to all day sunlight and can be found at altitudes ranging from sea-level up to 900 m. Adults are day flying and are on the wing from October to January.
Mnesarchaea fallax is a species of primitive moth in the family Mnesarchaeidae. It is endemic to New Zealand. This species is found in the Taranaki, Taupo, Nelson and Buller regions. It lives in a variety of habitats such as beech forest clearings, native podocarp forest, red tussock grasslands as well as in flax wetlands and at higher altitudes of up to 1300m. Much of the life history of this species is unknown and as at 2021 the host plants of this species have yet to be confirmed. The adult moths are on the wing from October to December. This species is classified as "Not Threatened" by the Department of Conservation.
Mnesarchaea fusca is a species of primitive moths in the family Mnesarchaeidae. This species was first described by Alfred Philpott in 1922, and is endemic to New Zealand. The larvae of the species is bright green when young but turns a brownish green when mature. Adults of this species are small and dark brown with patches of reddish yellow on its forewings. This species is found in Nelson and Marlborough Sounds. It inhabits poorly lit forest ravines and gullies or areas near shaded waterways. Adults are on the wing between December and February.
Mnesarchella fusilella is a species of primitive moths in the family Mnesarchaeidae. It is endemic to New Zealand and can be found in the Northland, Auckland, Waikato, Bay of Plenty, Hawke's Bay, Whanganui, and Wellington regions. It prefers well lit damp forests or moist fern-covered banks and lives at altitudes ranging from sea-level to approximately 500 m. Adults are on the wing from October to December. This species is normally day flying but males have been collected at night via light trapping.
Mnesarchella loxoscia is a species of primitive moth in the family Mnesarchaeidae. It is endemic to New Zealand. and is found in the Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupō, Gisborne, Rangitīkei, Wellington and the Marlborough Sounds regions. Adults of this species are normally on the wing from December and January but can be on the wing as early as October.
Mnesarchella hamadelpha is a species of primitive moth in the family Mnesarchaeidae. It is endemic to New Zealand and is found in the Wellington, Marlborough Sounds, Marlborough and Nelson regions. It is frequently found at altitudes of between 800 and 1400m but can be found as low as approximately 400 m. It is often found in damp moss covered but well lit native forest. This species is very similar in appearance to M. acuta. However although M. hamadelpha is present in the same locations as M. acuta, it is usually found at higher altitudes or at later times in the year. Adults are on the wing from November to February.
Mnesarchaea paracosma is a species of primitive moths in the family Mnesarchaeidae. It is endemic to New Zealand and can be found in the Kaikōura, mid and south Canterbury, MacKenzie, Otago Lakes, Central Otago, Dunedin, Fiordland and Southland areas. M. paracosma lives in a wide variety of habitats including tussock grasslands, shrubland, and damp native beech or podocarp forests, at a range of altitudes from around sea-level up to 1200 m. Adults of this species are on the wing from October to February and are day flying, although they are attracted to light at night.
Austramathes pessota is a species of moth in the family Noctuidae. It is endemic to New Zealand and is found in Northland, in the southern North Island and in the South Island, mainly on the eastern side of that island but is also present in Fiordland. It is not regarded as being present in either Dunedin or the Southland district. This species lives in shrubland at altitudes ranging from sea-level up to subalpine. As at 2017, the larvae have yet to be described or photographed but it is known that they feed on Melicytus alpinus and it is likely that Melicytus micranthus is also a host. Adults of this species are distinctively patterned and coloured. Its appearance differs from its close relatives such as A. purpurea as it lacks the purple hue that can be seen on the latter species forewings. It also differs from A. coelacantha as it is much darker and has a distinctive small, round, pale mark on its forewing. Adults are on the wing from December to April.
Ichneutica haedifrontella is a moth of the family Noctuidae. This species is endemic to New Zealand. It is only known from scattered areas in the North and South Islands. In the North Island it has only been collected in the Pouakai Range in Taranaki. In the South Island it is known from the Nelson, Buller, North Canterbury, Otago Lakes and Fiordland regions. It inhabits alpine to subalpine zones. The life history of this species is unknown as are the host species of its larvae in the wild. Larvae have been reared on species in the Chionochloa genus. Adults are on the wing from December to February and are attracted to light. This species has a smaller dwarf form that can be found in the Pouakai Range and at Dart Hut.
Ichneutica supersulcana is a moth of the family Noctuidae. This species is endemic to New Zealand and is only known from the Tararua Ranges and at Tongariro National Park. This species has been collected in subalpine tussock grasslands as well as subalpine shrubland and at the margins of Fuscospora cliffortioides forest. The life history of this species is unknown as are the host species of its larvae. The adults of this species are on the wing in February and are attracted to light. It appears to be restricted to higher altitudes in comparison to its close relative I. sulcana.I. sulcana and I. supersulcana are very similar in appearance with no reliable visible differences between the two having been discovered. However, there are distinct differences in the male abdomen and genitalia of these two species.
Mnesarchaea hudsoni is a species of primitive moths in the family Mnesarchaeidae. This species was first described by George William Gibbs in 2019, and is endemic to New Zealand. It is found in the Auckland, Coromandel, Bay of Plenty, Taupo, Gisborne, Hawkes Bay, Wairarapa and Wellington regions. This species inhabits cool, damp parts of native forest or lives alongside waterways and can be found at altitudes ranging from sea-level up to 800 m. Adults of this species are on the wing from February to April. M. hudsoni is very similar in appearance to its near relatives M. fusca and M. fallax but can be distinguished via differences in male genitalia.
Mnesarchella dugdalei is a species of primitive moths in the family Mnesarchaeidae. This species was first described by George William Gibbs in 2019, and is endemic to New Zealand. This species can be found in the Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupō, Gisborne and Hawke's Bay regions. M. dugdalei lives in damp but well lit forest sites at altitudes of between 200 m and 1300 m. Adults of this species are on the wing from October to December.
Mnesarchella falcata is a species of primitive moth in the family Mnesarchaeidae. This species was first described by George William Gibbs in 2019, and is endemic to New Zealand. It can be found in the Waikato, Taupō, Hawke's Bay and Rangitīkei regions
Mnesarchella ngahuru is a species of primitive moth in the family Mnesarchaeidae. This species is endemic to New Zealand and is found in the Taupō, Gisborne and Wellington regions.
Mnesarchella stellae is a species of primitive moths in the family Mnesarchaeidae. It is named in honour of Gibbs' mother Florence Stella Gibbs. This species is endemic to New Zealand and can only be found in the Nelson area for recording specimen localities as described by T. K. Crosby. This species is the largest in the Mnesarchella genus but otherwise is similar in appearance to other species contained in that genus. This species prefers very damp, dark native beech forest with plentiful moss and lives at altitudes of between 420 and 750 m. Adults of this species are on the wing in December and January.
Mnesarchella vulcanica is a species of primitive moths in the family Mnesarchaeidae. This species is endemic to New Zealand and can be found in the Taranaki, Taupō, Gisborne and Rangitīkei regions. It very similar in appearance to others within its genus. This species is most easily confused with M. falcata. M. vulcanica can only be distinguished by dissection and its differently shaped male genitalia. It lives in damp mountainous beech and podocarp forests at altitudes of between from 800 to 1400 m and is on the wing from December to February.
Tingena robiginosa is a species of moth in the family Oecophoridae. It is endemic to New Zealand and has been observed in the southern parts of the South Island. It has been observed in subalpine habitats at altitudes of between 2700 and 3500 ft amongst Hebe and Cassinia species. The adults of this species are on the wing in December and January.
Helastia alba is a moth of the family Geometridae. This species is endemic to New Zealand and is found only in the South Island. This species inhabits native forest or scrubland and can be observed in montane to subalpine Nothofagus dominant forests. It has also been observed at lower altitudes in native podocarp forests. Larvae of this species have been raised on mosses. Adults are on the wing from November to January and are nocturnal. This species is very similar in appearance to other species in the genus Helastia, but specimens can be distinguished by the dissection of their genitalia.
Helastia cryptica is a moth of the family Geometridae. It was first described by Robin C. Craw in 1987. This species is endemic to New Zealand and is found from mid Canterbury south. This preferred habitat of H. cryptica is native forest and scrub at altitudes ranging from lowland to subalpine. It has also been observed in human modified habitat. The larvae of this species has been observed on Melicytus alpinus, likely feeding on perched dead leaves and have been hypothesised as feeding on epiphytic mosses. Adults are nocturnal and are on the wing from November until January. Externally this species is indistinguishable from its close relative H. cymozeucta. However the distribution of these two species can assist in the correct identification of specimens.
