Heterocrossa epomiana is a species moth in the family Carposinidae. It is endemic to New Zealand and has been observed in Westland. Adults are on the wing in January. This species is visually very similar to H. gonosemana and to H. philpotti .

Taxonomy

This species was described by Edward Meyrick in 1885 using a specimen he collected at Otira Gorge at an altitude of 1,600 ft in January. [3] [4] [2] In 1907 Meyrick synonymised H. epomiana with H. gonosemana. [5] In 1922 Meyrick classified Heterocrossa as a synonym of the genus Carposina. [6] [7] George Hudson, in his 1928 publication The Butterflies and Moths of New Zealand, followed Meyrick and discussed this species as a synonym of Carposina gonosemana. [8] Later that same year Alfred Philpott examined the genitalia of the males of what was then known as C. gonoseana and C. epomiana and, after discussion with Meyrick, resurrected C. epomiana as a distinct species. [9] In 1978 Elwood Zimmerman argued that the genus Heterocrassa should not be a synonym of Carposina as the genitalia of the species within the genus Heterocrassa are distinctive. [6] In 1988 John S. Dugdale confirmed that the species belonged to the genus Heterocrossa. [2] The female holotype specimen is held at the Natural History Museum, London. [2]

Description

Meyrick described the species as follows:

Female. — 17 mm. Head and thorax white, irrorated with light grey. Palpi rather long, lower half dark fuscous, upper white. Antennae whitish. Abdomen and legs ochreous-whitish, anterior pair suffused with dark fuscous, middle pair greyish. Forewings elongate, narrow, oblong, costa moderately arched, somewhat bent at 1⁄3, apex round-pointed, hindmargin slightly sinuate, rather strongly oblique ; very pale grey, irrorated with white towards costa and hindmargin, and with scattered dark fuscous scales ; a blackish elongate spot along costa at base ; a blackish dot above inner margin near base ; costa with six small fuscous spots between 1⁄3 and apex ; discal and posterior tufts also preceded by small obscure fuscous spots : cilia pale grey mixed with whitish. Hindwings and cilia grey-whitish. [4]

This species is visually very similar to Heterocrossa gonosemana and to Heterocrossa philpotti . [2]

<i>Heterocrossa cryodana</i> Species of moth

Heterocrossa cryodana is a species of moth in the family Carposinidae. It is endemic to New Zealand and is found in the southern parts of the South Island as well as at Codfish Island / Whenua Hou. This moth is associated with plants in the Leptospermum genus. Adults are on the wing from September until January.

<i>Heterocrossa eriphylla</i> Species of moth

Heterocrossa eriphylla, also known as the lichen snoutlet moth, is a species of moth in the family Carposinidae. It is endemic to New Zealand and is found in the North Island and the northern parts of the South Island. This species is regarded as relatively uncommon and inhabits native forest. The larvae feed on the healing wounds of New Zealand beech trees Fuscospora fusca and Fuscospora truncata. It pupates at its feeding site and emerges from December onward. The adult moth is nocturnal and is attracted to light. During the day the moth rests on lichen covered tree trunks where their lichen mimicking colouration assists with their camouflage.

<i>Heterocrossa exochana</i> Species of moth

Heterocrossa exochana is a species of moth in the family Carposinidae. It is endemic to New Zealand and has been observed in the North and South Islands. The larvae of this species feed on the fruits of Muehlenbeckia species. The adult is on the wing from September until May and are attracted to light.

<i>Heterocrossa gonosemana</i> Species of moth

Heterocrossa gonosemana is a species of moth in the family Carposinidae. It is endemic to New Zealand and is found throughout the country. It inhabits native forest. Larvae feed on seeds and fruit of Griselinia lucida and possibly Griselinia littoralis. They can be extremely active when disturbed. This species overwinters as a pupa, enclosed in a cocoon, underneath its host plant. Adults are on the wing from November until February and can be found during the day resting on lichen covered tree trunks where they are well camouflaged. The adult is nocturnal and is attracted to light.

<i>Reductoderces microphanes</i> Species of moth

Reductoderces microphanes is a moth of the family Psychidae. This species is endemic to New Zealand. R. microphanes is a bagworm moth and its larvae likely feed on lichen or algae. Historically there has been some confusion over the identification of this species with George Hudson mistakenly describing and illustrating unnamed species and then attributing those descriptions and illustrations to this species. Charles Edwin Clarke discussed this species stating that it and its close relatives were active and able to be collected in damp mists before sunrise.

<i>Heterocrossa</i> Genus of moths

Heterocrossa is a genus of moths in the Carposinidae family. It is endemic to New Zealand. This genus was previously regarded as a synonym of the genus Carposina. However Elwood C. Zimmerman in Insects of Hawaii removed Heterocrossa from synonymy with Carposina. Zimmerman argued that as the genitalia of Heterocrossa and Carposina are distinct, Heterocrossa should not be regarded as a synonym of Carposina. This was agreed with by John S. Dugdale in his annotated catalogue of New Zealand Lepidoptera.
