Stigmella progama


Stigmella progama is a species of moth in the family Nepticulidae. This species is endemic to New Zealand and has only been collected on Bold Peak in the Humboldt Mountains. Larvae are leaf miners although their larval host plant has yet to be determined. It is classified as "Data Deficient" by the Department of Conservation. S. progama has only been collected on Bold Peak, in the Humboldt Ranges, in Otago.

Taxonomy

This species was first described by Edward Meyrick in 1924 using a female specimen collected by George Hudson at Bold Peak, Lake Wakatipu in the Humboldt Mountains at 4000 ft. on the 5 January. Meyrick named the species Nepticula progama. George Hudson discussed and illustrated the species under that name in his 1928 publication The Butterflies and Moths of New Zealand. In 1988 John S. Dugdale assigned this species to the genus Stigmella. This placement was confirmed in 1989. The female holotype specimen is held at the Natural [History Museum, London].

Description

Meyrick described this species as follows:
Although similar in appearance to S. oriastra, S. progama can be distinguished as it has a submedial brown area on the forewing. As at 1989, male of the species has yet to be collected.

Distribution

This species is endemic to New Zealand. It has only been found in its type locality in the Humboldt Mountains in Otago at approximately 1200 m. above sea-level.

Biology and behaviour

Larvae of this species are leaf miners. Adults of this species are on the wing in January.

Conservation status

This species has been classified as having the "Data Deficient" conservation status under the New Zealand Threat Classification System.
