Summary: | Lasionycta subdita (Möschler) Figs 9, 140, 198. Map 3 Dianthoecia subdita Möschler, 1860: 363. Mamestra subdita Smith 1893a: 129. Lasionycta subdita McDunnough 1938: 71. Anarta membrosa Morrison, 1875a: 101. Anarta membranosa Smith 1893a: 294, misspelling. Lasionycta membrosa McDunnough 1938: 71. Type material. Dianthoecia subdita : holotype ♁ [ZMHB, not examined]. 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.
