Amblyptilia epotis is a moth of the family Pterophoridae. [1] It is endemic to New Zealand and is found in the South and Stewart Islands. It inhabits mountainous terrain covered in alpine vegetation or alternatively alpine wetland habitat. The adults of this species are on the wing from February to March. In appearance the adults of this species are variable in colour however this species can be distinguished from similar species by the oblique apical streak on its forewings as well as the patch of white on the costa cilia towards the apex of the forewing.

Taxonomy

This species was first described by Edward Meyrick in 1905 and named Platyptilia epotis using a female specimen collected at the Humboldt Range by George Hudson. [3] [4] In 1910 Meyrick again discussed this species as Hudson sent further specimens to him including the male of the species. [5] In 1928 Hudson, in his publication, The butterflies and moths of New Zealand, placed this species in the genus Stenoptilia. [6] However Alfred Philpott, also in 1928, considered this species under its originally published name Platyptilia epotis. [7] Philpott discussed the male genitalia of this species with the aim of separating species contained in the genera Platyptilia and Stenoptilia. [7] In 1971 Dugdale also discussed the species under the name Platyptilia epotis but in 1988 dealt with this species under the name Stenoptilia epotis. [8] [4] In 2010 the New Zealand Inventory of Biodiversity discussed this species under the name Amblyptilia epotis. [1] The holotype specimen is held at the Natural History Museum, London. [4]

Meyrick originally described this species as follows:

♀. 25 mm. Head white. Palpi 2+12, greyish-ochreous sprinkled with dark fuscous, white above. Antennas grey. Thorax whitish suffusedly sprinkled with brownish-ochreous, patagia becoming clear white posteriorly. Abdomen white, partially suffused with pale brownish-ochreous except towards base. Legs white, anterior femora and tibiae fuscous. Fore-wings with apex pointed, subfalcate, termen rather deeply concave ; pale brownish-ochreous densely irrorated with white, broadly suffused with white towards costa and dorsum on posterior half ; basal 14 of costa irrorated with dark fuscous, thence a narrow dark fuscous costal streak reaching to 34; a dot of two or three dark fuscous scales in disc at 25 ; a short transverse blackish-fuscous mark before cleft ; a strong oblique blackish streak from apex to anterior half of lower margin of first segment, where it is broadest ; an undefined blackish-fuscous longitudinal dash in centre of basal half of second segment : cilia whitish, with a dark fuscous spot above apex, an interrupted blackish basal line on central third of termen, and two or three blackish scales on dorsum at 23. Hindwings pale fuscous, second segment whitish-tinged ; cilia whitish-fuscous ; two or three fine blackish hair scales in dorsal cilia of third segment beyond middle. [3]

This species is variable in colour with specimens from the Mount Arthur tableland being more ochreous and less white than the type specimen. [5] Hudson states that the species can be distinguished from similar species by the oblique apical streak on its forewings as well as a patch of white on the costa cilia towards the apex of the forewing. [6]

Zealandopterix zonodoxa is a moth of the family Micropterigidae. It endemic to New Zealand and is found from the Hawkes Bay north as well as on Poor Knights, Little Barrier and Great Barrier Islands. It is the smallest micropterigid in New Zealand and the shiny white markings on the forewing of this species are variable. It is a day flying moth, but has been collected using UV light. Adults are on the wing from September to March and the species has been witnessed visiting the flowers of Nikau and Cordyline pumilio in large numbers. It inhabits a wide variety of moist indigenous forest but is associated with forests in which podocarps are common. Larvae have been sieved from rotten wood on the floor of a mixed podocarp/broadleaf forest or extracted from moss or from bryophytes.

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 to 1400m but can be found as low as approximately 400 m. It is often found in damp moss covered but well lit native forest.

It is present on the North Island volcanic plateau as well as Little Bush Reserve in Hawkes Bay in the North Island as well as in tussock grassland, alpine and subalpine shrubland and in alpine forest. Larvae have been recorded as feeding on grasses, a pupa has been found in a cocoon under the bark of a tree and adult moths are on the wing from October to January.

This species flies in bright sunshine and is likely a very local species. It is likely that this species probably belongs to another genus and as such this species is also known as Cryptolechia (s.l.) semnodes.
