Taxonomy

This species was originally described by Alfred Philpott in 1927 using a specimen collected from Cooper's Knob, Banks Peninsula by Stewart Lindsay and named Carposina maculosa. [2] [3] George Hudson discussed this species under this name in his 1928 publication The Butterflies and Moths of New Zealand. [4] In 1978 Elwood Zimmerman argued that the genus Heterocrassa should not be a synonym of Carposina as the genitalia in this genus are distinctive. [5] Subsequently John S. Dugdale placed this species within the genus Heterocrossa. [2] [6] The holotype specimen is held at the New Zealand Arthropod Collection. [2]

Description

Philpott originally described the species as follows:

♂ ♀ 18 mm. Head, antennae and thorax light buff. Palpi light buff mixed with ochreous on lower half externally. Abdomen ochreous-white. Legs ochreous-white, anterior and middle parts infuscated. Forewings moderate, costa moderately arched at base, thence straight, apex subacute, termen straight, oblique; light buff finely irrorated with pale fuscous; markings fuscous-black; a dot beneath costa near base and a similar one obliquely before it above dorsum; a minute dot beneath costa at 14 and a much larger one beneath it below fold; a dot in disc beyond these; a dot beneath costa and two below it in disc before 12; a small dot beneath costa between these and 34; two or three dots touching each other and forming a short transverse striga at 34; an obscure irregular striga from costa at 45 to tornus; a series round termen: fringes whitish-buff. Hindwings and fringes shining white. [3]

Distribution

This species is endemic to New Zealand. [1] [6] It is known from the Lyttelton Hills and Otago. [7] Other than the type locality, this species has also been collected from Hoon Hay Bush. [3]

Biology and behaviour

The adult moths are on the wing in November. [4]

Host species and habitat

The larvae feed on Hoheria angustifolia and Plagianthus regius . [7]

Conservation status

This species has been classified as having the "Data Deficient" conservation status under the New Zealand Threat Classification System. [8] The main risks to this species are likely habitat fragmentation and loss. [7]

Dugdale in his annotated catalogue of New Zealand lepidoptera.
