Taxonomy

This species was described by Francis Walker in 1866 using material collected in Nelson by T. R. Oxley in 1860 and named Tinea contactella.[1][2] In 1905 Edward Meyrick placed this species within the genus Heterocrossa.[3] In 1911, thinking he was describing a new species, Edward Meyrick named the moth Carposina amalodes.[4][1] In 1922 Meyrick listed Heterocrossa as a synonym for Carposina.[5] George Hudson, in his 1928 publication The Butterflies and Moths of New Zealand, discusses this species under both the names Carposina contactella and Carposina amalodes.[6] 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 synonymised the name Carposina amalodes and assigned the species to the genus Heterocrossa.[1] The lectotype specimen is held at the Natural History Museum, London.[1]

Description

Meyrick described the species as follows:

♀︎. 14–15 mm. Head white. Palpi ​2 1⁄2, white, lower longitudinal half blackish. Antennas white, obscurely ringed with fuscous. Thorax whitish-ochreous mixed with dark grey, collar and patagia white. Abdomen pale greyish-ochreous. Fore-wings elongate, narrow, costa moderately arched, apex round-pointed, termen very oblique, almost straight, rounded beneath; grey, irregularly irrorated with dark grey and white ; a broad irregular-edged white suffusion extending along anterior half of costa, and reaching ​2⁄3 across wing ; three or four small black dots on costa anteriorly, second forming a short strigula ; a narrow oblique-transverse pale ochreous spot edged with black below middle at ​1⁄3 ; a black dot above middle of disc, and a small pale ochreous sometimes blackish-mixed spot below it ; three small faint whitish-ochreous spots arranged in a triangle in disc beyond middle ; all these ochreous spots are ringed with white suffusion ; an undefined angulated dark subterminal shade, marked with black on veins ; a series of blackish dots on posterior half of costa and termen : cilia light grey irrorated with white, basal half obscurely barred with whitish. Hind-wings grey, paler anteriorly ; cilia whitish.[3]
