Notoreas ischnocyma is a species of moth in the family Geometridae. This species is endemic to New Zealand. This species is found in Canterbury and Otago.
Taxonomy
[edit | edit source]_plate_8_fig_27.jpg){kind=link}
Notoreas ischnocyma was described by Edward Meyrick in 1905 using material collected at Castle Hill by George Hudson at an elevation of 1700 meters.[1][2] Hudson had previously illustrated the specimen in his 1898 book New Zealand Moths and Butterflies (Macro-lepidoptera) but had included it within the species N. isoleuca.[3][4] Hudson subsequently agreed with Meyrick and discussed and illustrated this species under the new species name in The Butterflies and Moths of New Zealand.[5]
The genus Notoreas was reviewed in 1986 by R. C. Craw and the placement of this species within it was confirmed.[6] However species within the genus Notoreas are currently regarded as being in need of revision.[7] The holotype specimen is held at the Natural History Museum, London.[3]
Description
[edit | edit source]Meyrick described the species as follows:
♂︎. 20 mm. Head and thorax dark fuscous. Fore-wings triangular, costa slightly arched, termen obliquely rounded; dark fuscous, with some scattered yellow-whitish scales; subbasal, first, median,second, and subterminal lines slender, whitish, subbasal straight, first nearly straight, somewhat irregular, median indistinct, curved outwards in disc, second waved throughout, angulated in middle, indented beneath middle, subterminal irregularly waved: cilia white, basal half barred with dark fuscous. Hind-wings with ground colour, median, second, and subterminal lines, and cilia as in fore-wings.[2]
N. ischnocyma can be distinguished from similar species by the slender second wavy line on its forewings.[2][5]
Distribution
[edit | edit source]
This species is endemic to New Zealand.[8][9] Other than the type locality of Castle Hill, N. ischnocyma has also been found in the Hawkdun and the Dansey ecological districts in Otago.[10][11]
Biology and behaviour
[edit | edit source]This day flying species is on the wing in December and January.[5][11]
Habitat and host species
[edit | edit source]This species inhabits high alpine stunted vegetation and herb fields.[5][11] Larvae of species within the genus Notoreas feed exclusively on plants within the genera Pimelea and Kelleria.[12]
