Type locality: Labrador. Anarta membrosa : type lost. Type locality: New Hampshire. The type is presumed lost but the name was synonymized with L . subdita by Lafontaine and Kononenko (1988) based on details of the original description. Diagnosis. This northeastern species can be identified by a combination of lightgray forewing with black orbicular and reniform spots filled with pale-gray scales, black claviform spot, and mottled distal forewing with a checkered fringe. It is most likely to be confused with L . taigata , also found in northeastern North America, but is readily distinguished from it by differences in the genitalia given in the key to species-groups. The male digitus bears a stout basal spine. Th ose of the other species in the speciesgroup have a broad basal flange. Females have a rounder corpus bursae and more blunt appendix bursae than the western species. The CO1 DNA of L . subdita differs by more than 1.8 % from that of L . conjugata (Smith) and L . fergusoni sp. n. Distribution and biology. Lasionycta subdita is predominantly a subarctic species. It occurs across Labrador, Quebec, and Ontario to Churchill, Manitoba on the west shore of Hudson Bay. A disjunct population is in the White Mountains of New Hampshire. Th e adults are nocturnal and come to light. Th ey have been collected in July. : Published as part of Crabo, Lars & Lafontaine, Donald, 2009, A Revision of Lasionycta Aurivillius (Lepidoptera: Noctuidae) for North America and notes on Eurasian species, with descriptions of 17 new species, 6 new subspecies, a new genus, and two new species of Tricholita Grote, pp. 1-156 in ZooKeys 30 (30) on pages 17-18, DOI: 10.3897/zookeys.30.308, http://zenodo.org/record/576576 : {"references": ["Moschler HB (1860) Beitrage zur Lepidopteren-Fauna von Labrador.
