Tingena epichalca
Tingena epichalca is a species of moth in the family Oecophoridae. It is endemic to New Zealand and has been observed at Arthur's Pass and in the mountains around Otira. This species is very similar in appearance to Tingena aphrontis but can be distinguished on the basis of different antennal ciliations of the male of the species. Adults are on the wing in January and inhabit alpine zones, frequenting alpine vegetation on the edge of screes at altitudes of between 3 – 4000 ft.

Taxonomy 
This species was originally described by Edward Meyrick in 1886 using specimens collected at Arthur's Pass in January and named Cremnogenes epichalca. In 1915 Meyrick discussed this species under the name Borkhausenia epichalca. In 1926 Alfred Philpott discussed and illustrated the genitalia of the male of this species. In 1928 George Hudson also discussed and illustrated this species in his book The butterflies and moths of New Zealand. In 1988 J. S. Dugdale placed this species within the genus Tingena. The male lectotype is held at the Natural History Museum, London.
