description: <i>Sympistis sobek</i> Troubridge sp. n. (Figs. E-10, N-3, S-7) <b>Diagnosis.</b> The dorsal hindwing of species of the <i>S. homogena</i> group falls into two categories, the dark terminal band is either sharply defined or the transition between it and the discal area is more gradual. Like <i>S. hathor</i> and <i>S. septu</i>, the terminal band of <i>S. sobek</i> is sharply defined, but the forewing is dark, dusky gray rather than brown as in <i>S. hathor</i> and <i>S. septu</i>. <i>Sympistis sobek</i> most closely resembles and may fly with <i>S. homogena</i> and <i>S. cherti</i> <b>sp. n.</b>, but the transition between the dark terminal band the discal area is more gradual in these species. <b>Description</b>. Antennae filiform, head and prothoracic collar a mix of brown and black scales; thorax and tegulae a mix of black and white scales; abdomen light grayish brown. Coremata with brushes, levers, and pockets present on base of male abdomen. Forewing length 15-16 mm. <b>Dorsal forewing</b> ground color a mix of black, white, and light grayish brown scales giving a powdery dark gray overall appearance; postmedial, antemedial and basal lines black; postmedial line edged distally by a band of lighter gray which blends to dark gray towards subterminal line; antemedial line narrowly bordered basally with light gray to grayish brown scales, jagged, light gray subterminal line extends through middle of dark gray subterminal area; terminal line black; orbicular and reniform spots outlined with black scales, filled with light gray and dusted with black scales; fringe with light grayish brown basal line, a black medial line and dark gray terminal area that is checkered with darker scales between veins. <b>Dorsal hindwing</b> basal area with white scales under long gray hairs giving a dirty off-white appearance; veins with scattered gray scales; discal lunule faint; sharply defined terminal band dark gray; fringe light grayish brown basally, white terminal line and dark gray median line. <b>Male genitalia</b>. (Fig. N-3) Valve shaped like the prow of canoe, with distinct corona; ampulla of clasper more-or-less parallel sided, terminal spine arcing from posterior margin; clavus well-developed, about as tall as wide. Vesica with small basal, ventral diverticulum bends slightly upward; a patch of short, sparse cornuti on left near base and second patch of much longer cornuti on right at base; a ribbon of long cornuti extends along ventral margin of apical ¾ of vesica; a second ribbon of longer, stouter cornuti extends along apical ½ of vesica, nearly to apex, where vesica narrows and bends downward toward patch of long cornuti and single apical spine. <b>Female genitalia</b>. (Fig. S-7) Ovipositor lobes rounded, apex with long, fine setae, corona of short setae mid way down -these setae arc anteriorly; a ruff of longer, finer setae encircles ovipositor lobes at base; a Y-shaped sclerite occurs on ventral surface of ductus bursae at ostium bursae, ductus bursae about same length as corpus bursae, doubles in width at a point ca. ½ of the way from ostium bursae to appendix bursae; appendix bursae sac-like, narrowing to ductus seminalis at anterior end, meeting ductus bursae on right side of posterior end; corpus bursae ellipsoidal, about ¾ as large as appendix bursae, arises via narrow duct from left side of appendix bursae near ductus bursae, elongate signae on dorsal and ventral sides. <b>Type material</b>. <b>Holotype</b> female: USA, Oregon, Deschutes Co., Horse Ridge Summit, 3 ix 1995, J. Troubridge, in the CNC. <b>Paratypes:</b> 4♂ 8♀: <b>Oregon</b>: same data as holotype, 2♀. <b>California</b>: Mt Shasta, 41° 21' N, 122° 12' W, 7680', 27 viii 2000, J. Troubridge, 1♂ 2♀; Mt Shasta, Siskiyou Co., 41° 21' N, 122° 13' W, 7300', 15 viii 1998, J. Troubridge, 3♂ 3♀. <b>Etymology.</b> From Egyptian mythology, Sobek was represented as a crocodile or as a man with the head of a crocodile; he was a god who brought fertility from the Nile waters. It is a noun in apposition. <b>Distribution.</b> This species has been collected at mid to high elevation in eastern Oregon and northern California.
