Taxonomy

This species was first described by Charles E. Clarke in 1926 using a specimen collected by him at Hope Arm, Lake Manapouri and named Tortrix cuneata. [2] [3] In 1971 John S. Dugdale assigned Tortrix cuneata to the genus Ericodesma. [4] The holotype specimen is held at the Auckland War Memorial Museum. [2]

Description

Clarke described the species as follows:

♂. 13 mm. Head and thorax light grey; palpi moderate. Antennae grey, antennal ciliations 12. Abdomen pale ochreous-grey. Forewings elongate, costa moderately arched, apex bluntly pointed, termen slightly rounded, oblique; pale grey with a number of small obscure dots with tendency to form rows; a transverse blunt wedge-shaped red bar at 12 of dorsum, reaching half-way across wing. Hindwings pale ochreous-grey: cilia pale grey. [3]

Distribution

This species is endemic to New Zealand. [1] [5] E. cuneata can be found at Taupō, Otago Lakes and Fiordland. [6] The species, although rare, can be found frequently at The Wilderness in Southland. [7]

Biology and behaviour

The larvae of this species web leaves together on the foliated stems of its host plant. [8]

Host species and habitat

The larvae of E. cuneata feed on Corokia cotoneaster , (korokio). [6] However the moth has not been associated with urban plantings of its host. [6] The adult moth has been collected in beech forest habitat, [3] as well as at strongly leached terraces and plains commonly called "wilderness". [7]

Conservation status

This species has been classified as having the "At Risk, Naturally Uncommon" conservation status under the New Zealand Threat Classification System. [9]
