Lasionycta conjugata (Smith) Figs 10, 141, 199. Map 3 Scotogramma conjugata Smith, 1899: 41. Lasionycta conjugata; McDunnough 1938: 71. Type material. Lectotype ��� [USNM, examined]. Type locality: Garfi eld County, Colorado, [USA]. Th e lectotype was designated by Todd (1982: 54). Diagnosis. Lasionycta conjugata has a pale-gray forewing with jet-black lines, spots, and bars between the claviform spot and postmedial line and orbicular and reniform spots. It occurs to the south of the range of L. fergusoni. Th is species is similar but its forewing is darker blue gray and lacks the black bars. Th e antennal segments of L. conjugata are triangular whereas those of L. fergusoni are T-shaped with narrow distal segments. The flange of the digitus is less prominent in L. conjugata than in L. fergusoni. Th e female genitalia are similar. Th e CO1 sequences of L. conjugata and L. fergusoni differ by at least 1.7 %. Distribution and biology. Lasionycta conjugata occurs in the Rocky Mountains from central Utah and Colorado north to the Beartooth Plateau on the Montana-Wyoming border. It flies in subalpine forests and is nocturnal. Adults have been collected from early July to late August.
