Taxonomy

This species was first described by Edward Meyrick in 1919 using a specimen collected by George Hudson at Wainuiomata in December and named Borkhausenia ancogramma.[3] George Hudson discussed and illustrated this species in his 1928 book The butterflies and moths of New Zealand also under the name Borkhausenia ancogramma.[4] In 1939 Hudson synonymised Borkhausenia latens and Borkhausenia bellatula with this species.[5][2] In 1988 J. S. Dugdale placed this species in the genus Tingena and confirmed synonyms established by Hudson.[2] When discussing Hudson's illustration of this species Dugdale argued that it should be regarded as dubious as the illustration "has a dark patch on the dorsum just before the tornus which is lacking in the holotype".[2] The holotype specimen is held at the Natural History Museum, London.[2]
Description
Meyrick described this species as follows:
♂. 16 mm. Head ochreous-grey-whitish sprinkled with fuscous. Palpi ochreous-whitish, basal half of second joint and a subapical ring dark fuscous, terminal joint 2⁄3 of second, with dark-fuscous subbasal and subapical rings. Antennal ciliations under 1. Thorax fuscous somewhat mixed with ocherous-grey-whitish, suffused with dark fuscous towards margins. Abdomen whitish-ochreous mixed with light-brownish. Forewings elongate, costa gently arched, apex obtuse, termen rounded, rather strongly oblique ; pale ochreous irregularlv sprinkled with light-brownish and a few dark-fuscous scales ; a thick dorsal streak of pale ground-colour from base to near tornus, sprinkled with light fuscous on a patch beyond middle and with dark fuscous on dorsal edge towards base, margined above by an obtusely angulated dark- fuscous streak (suffused above with fuscous) from base of costa to plical stigma, posteriorly rather expanded and with a short prominence beneath second discal stigma, extremity obliquely truncate, surrounded posteriorly with fuscous suffusion and some dark-fuscous scales ; stigmata dark fuscous, plical rather obliquely before first discal, second discal transverse, an additional cloudv dot on margin of dorsal streak between first and second discal ; blotches of fuscous suffusion on costa at \ and middle, latter connected by second discal stigma with dark posterior margin of dorsal streak : a fuscous spot on costa at a, with very faint indications of subterminal line ; two cloudv fuscous costal dots near apex : cilia whitish-ochreous speckled with light-brownish. Hindwings very pale greyish : cilia whitish-ochreous.[3]
