Taxonomy

This species was first described by Edward Meyrick in 1915 and named Borkhausenia crotala.[3] Meyrick was proposing the species name B. crotala for his conception of Walker's Oecophora contextella.[2][4] George Hudson discussed and illustrated this species under the name Borkhausenia plagiatella in his 1928 publication The butterflies and moths of New Zealand, having synonymised B. crotala in that publication.[5] Alfred Philpott also discussed this species under the name B. plagiatella.[6] In that publication Philpott recommended that the two forms encapsulated by the concepts B. crotala and B. plagiatella be separated on the basis of the differences in the male genitalia.[6] In 1988 J. S. Dugdale resurrected the species originally described by Meyrick in 1915 and placed it within the genus Tingena.[2] The male lectotype, collected in Dunedin, is held in the Natural History Museum, London.[2]

Description

This species is variable in appearance.[2] T. crotala has a white scaled head.[2] Meyrick described his conception of Walker's B. contextella, later to be named B. crotala, as follows:

Male, female. — 13-15 mm. Head ochreous-white. Palpi white, second joint irrorated with dark fuscous except at apex, terminal joint with a cloudy dark fuscous submedian ring. Antennae grey. Thorax whitish or ochreous-white, anterior margin suffused with dark fuscous. Abdomen whitish-ochreous. Legs dark fuscous, middle tibiae with central and apical rings, hairs of posterior tibiae, and apex of all tarsal joints ochreous-whitish. Forewings moderate, costa moderately arched, apex rounded, hindmargin very obliquely rounded ; white, irregularly irrorated with fuscous-grey ; a cloudy dark grey fascia from base of costa, and a second from costa at 1⁄4, confluent in middle and extending almost to inner margin at 1⁄3, mixed with ochreous at apex, and margined posteriorly by an oblique blackish streak below middle, sometimes connected with a blackish dot in disc before middle ; a cloudy dark grey fascia spot on costa at 4⁄5, giving rise to a curved cloudy blackish-grey transverse line to anal angle ; all these grey markings are sometimes partially suffused and confluent ; a cloudy dark grey apical spot : cilia white, irregularly mixed with dark grey, forming a cloudy spot at apex and anal angle. Hind-wings pale grey ; cilia grey-whitish.[4]

Distribution

T. crotala is endemic to New Zealand and has been observed in Auckland, Waimarino, Christchurch, Dunedin, Invercargill, Lake Wakatipu.[7][3][1]

Behaviour

Adults are on the wing in November and December.[8]

Habitat

This species has been collected in native forest but is also said to have an affinity with Cupressus macrocarpa.[8] The larvae of this species feeds on leaf litter.[9]
