Lasionycta flanda (Smith), stat. rev. Figs 30, 148, 204. Map 9 Anarta flanda Smith, 1908: 111. Lasiestra leucocycla flanda McDunnough 1938: 71. Lasionycta leucocycla flanda Lafontaine et al. 1986: 257. Type material. Lectotype ♁ [AMNH, examined]. Type locality: Newfoundland. Th e male lectotype was designated by Todd (1982: 84). Diagnosis. Lasionycta flanda resembles L . leucocycla but has a yellow-brown hindwing and blue-gray forewing with patches of yellow scales. It has narrow biserrate male antenna and genitalia indistinguishable from those of L . leucocycla , but the eye is rounded, normal in size, whereas those of L . leucocycla are reduced in size. Lasionycta flanda is restricted to Newfoundland and Labrador. It is only likely to be confused with L . l . moeschleri in Labrador but can be distinguished by hindwing color and eye size. Lasionycta flanda tends to be larger than L . l . moeschleri (12–13 mm for L . flanda males compared with 10–12 mm for L . l . moeschleri males). Th e female bursa is similar to that of L . leucocycla but is larger. The single available L . flanda CO1 sequence of is identical to that of L . anthracina and similar to those of L . leucocycla . Distribution and biology. Lasionycta flanda is found on the island of Newfoundland and at Goose Bay in eastern Labrador and occurs on tundra. It has been collected from mid-July to early August. It is nocturnal and comes to light (D. Macaulay pers. comm.). Remarks. Lafontaine et al. (1986) treated L . flanda as an endemic Newfoundland subspecies of L . leucocycla , but the taxa are sympatric in Labrador. Two typical, dusky L . flanda females with round eyes from Goose Bay were found amongst L . l . moeschleri at the CNC. Lasionycta leucocycla from nearby Cartwright and Hopedale have reduced ellipsoid eyes and white hindwings typical for L . leucocycla moeschleri .
