Tingena marcida is a species of moth in the family Oecophoridae. It is endemic to New Zealand and has been observed in Canterbury. Adults are on the wing in September and October.

Taxonomy[edit]

This species was described by Alfred Philpott in 1927 using specimens collected at Bottle Lake in Christchurch by Stewart Lindsay and named Borkhausenia marcida.[2][3] George Hudson discussed this species under that name in his 1928 publication The Moths and Butterflies of New Zealand.[4] In 1988 John S. Dugdale assigned this species to the genus Tingena.[3] The holotype specimen is held at the Canterbury Museum.[3]

Description[edit]

Philpott described this species as follows:

♂ ♀ 15–17 mm. Head, palpi and thorax brownish-grey. Antennae brown annulated with grey, ciliations in ♂ 1. Abdomen bronzy, mixed with grey basally, segmental divisions grey. Legs brown mixed with grey. Forewings moderate, costa moderately arched, apex rounded, termen very oblique; white, densely irrorated with pale bronzy-brownish; markings sometimes entirely absent but usually a spot of paler or brighter bronzy brown beneath fold at 13 and a similar spot in disc at 23, a spot on costa at 45 and another on tornus; dorsal spots margined posteriorly with white: fringes concolorous with wing, tips darker. Hindwings pale greyish-fuscous: fringes fuscous-grey with dark basal line.[2]

Philpott pointed out that it is difficult to confirm the identity of this species visually as a result of its lack of markings.[2] However the genitalia of this species is characteristic and gives more reliable evidence of the species identity.[2] Hudson stated that this species was very similar to and might be confused with Tingena innotella.[4] However T. marcida could be distinguished from T. innotella by the terminal appendages of the male of the species.[3] As a result of its greyish colour T. marcida could also be confused with Izatha psychra however T. marcida has antennal pecten which is lacking in the Izatha species.[5]

Distribution[edit]

This species is endemic to New Zealand.[1] It has been collected at its type locality of Bottle Lake as well as Governor's Bay and Mount Grey, all in Canterbury.[4] This species has also been found in three sites of ecological significance in Christchurch as set out in the Christchurch District Plan.[6][7][8]

Behaviour[edit]

The adults of this species are on the wing in September and October.[9]
