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 1922 Meyrick classified Heterocrossa as a synonym of the genus Carposina.[5][6] George Hudson, in his 1928 publication The Butterflies and Moths of New Zealand, discusses this species as a synonym of Carposina gonosemana.[7] 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.[5] In 1988 John S. Dugdale assigned the species back to the genus Heterocrossa.[2] The holotype specimen is held at the Natural History Museum, London.[2]

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

Distribution

This species is endemic to New Zealand.[1][8] It has been collected in Westland.[4]

gollark: I see.
gollark: Also, do you intend to create an "anarchy esolangs"?
gollark: I mean, people got randomly banned and such occasionally, which was bad. But you could just not do this.
