Mnesictena flavidalis

Mnesictena flavidalis is a moth in the family Crambidae. It was described by Edward Doubleday in 1843. It is endemic to New Zealand.

Taxonomy
This species was first described by Edward Doubleday in Ernst Dieffenbach's book Travels in New Zealand: with contributions to the geography, geology, botany and natural history of the country and named Margaritia flavidalis. In 1899 Hampson placed this species in the genus Mnesictena. In 1983 G. E. Munroe synonymised the genus Mnesictena with Udea. However in 1988 John S. Dugdale treated Mnesictena as a valid genus. Dugdale's treatment was followed in 2011 by Richard Mally and Matthias Nuss. The male holotype specimen, collected in Auckland by A. Sinclair, is held at the Natural History Museum, London.

Description
Doubleday described this species as follows: "All the wings ochraceous, the outer margins with a series of minute dots. Anterior wings with a faint striga near the base, a still fainter one near the middle, and a more distinct much-waved one near the outer margin, and two discoidal stigmatiform spots fuscous. Posterior wings with a discoidal spot, preceded towards the anterior margin by a smaller one, a transverse striga beyond the middle, and the anal angle fuscous."
