Diagnosis. — Most similar to S. cilium, but male of S. depravata with bipectinate antenna (Fig. 19). Forewing ground color light brown, pattern in male less distinct than in S. cilium. Male genitalia with ampulla narrower and apex more produced than in S. umbraculata (compare Figs. 310, 340 to 312, 342). Female genitalia with distal margin of ventral plate of ostium bursa straight (Figs. 404, 436); signum shorter and at a steeper angle than in S. umbraculata (compare Fig. 404 to 406).
Description. Adult Male. — Head: Basal segment of labial palpus cream variably mixed with gray scales; median segment cream variably mixed with gray scales; apical segment cream.
Frons with short scales cream; long scales cream; lateral spots at eye margin absent; vertex cream. Antenna bipectinate; scape cream; flagellum cream.
Thorax: Patagium light brown with a brown median transverse band. Tegula light brown. Mesothorax cream to light brown. Underside of thorax cream. Prothoracic femur cream to fuscous; tibia with lateral scale tufts not extending beyond first tarsal segment, cream and fuscous, subapical spot absent; tarsal segments fuscous, proximal and apical ring cream on segment 1, apical rings on segments 2 and 5 cream, no apical rings on segments 3 and 4. Mesothoracic femur cream; tibia cream, inner spur more than twice length of outer spur, mediolateral surface thinly devoid of scales on both spurs; tarsal segments cream with pale fuscous bases. Metathoracic femur cream; tibia cream (can have fuscous scales present); tarsal segments cream.
Foreiving: Length, 12-14 mm; ground color light brown; basal line absent; longitudinal black dash at base absent; R vein not contrasting in color; basal scale patch between R and Cu veins absent; basal half circle scale patch below Cu vein absent; antemedial line absent; claviform spot absent; basal scale patch absent; gray patch covering anal cell and half of cell CuA2 absent; oblique brown mark from fifth outer marginal spot to vein CuA2 absent; curved white line from antemedial line to postmedial line absent; orbicular spot oval, indistinct, cream, outlined in brown; reniform spot round, black; white scales along Cu vein from orbicular spot to junction of veins M3 and CuAl which extend down veins M3, CuAl, and CuA2 to postmedial line (can be indistinct to absent); postmedial line black, from just below costa to posterior margin, wavy; postmedian band undifferentiated; black scale patches in middle of cells in postmedian area absent; subterminal line white, indistinct (can be absent on worn specimens); apex lacking a white patch; minute black spots along outer margin to black triangular-shaped spots along outer margin; fringe pale gray. Underside ground color pale gray; outer margin with black spots becoming absent with only the margin gray; reniform spot darker, indistinct.
Hindzving: Ground color white suffused with pale gray; apex, outer margin, and veins with pale gray scales; fringe pale gray. Underside
ground color pale gray, especially along costa, outer margin, and veins, proximal half of wing cells white; outer margin spots absent; no spot on underside.
Abdomen: Dorsum pale gray; venter pale gray; disto-lateral black spots on sternites absent; 8th tergite with spiculate patches absent on caudal margin.
Genitalia: Uncus curved in basal half; maintaining width throughout three-fourths length, narrowing to pointed apex; setae few or absent. Scaphium elongate, weakly developed. Tegumen lacking a pair of projecting arms on upper third. Costa sinuate (Figs. 310, 340). Costal process a minute knob; in middle of costa; perpendicular to costa of valve. Cucullus apex round; produced. Anellifer with lightly sclerotized plate bearing setae absent. Ampulla elongate, slightly curved with a pointed apex; extending to just below apex of valve (Figs. 310, 340). Clasper proper absent. Clavus absent. Sacculus broadest at base, gradually tapering distally; apex pointed. Valvula narrower than valve; well differentiated from valve, apex free; apex round; indentation absent. Coremata reduced, closely appressed to sacculus; no distinct lobes. Juxta a rectangular band, median process elongate, expanding into an apical plate, ventral margin straight to convex. Anellus membranous. Vinculum U-shaped with a narrow base. Aedoeagus straight; coecum smaller in diameter than shaft; patch of spines absent on apex of membranous sheath surrounding aedoeagus. Vesica curved dorsally; short, less than 0.75 length of aedoeagus; apicobasal cornutal patch a narrow ribbon; length moderate, to less than middle of vesica; cornuti in form of minute flat granules; lateral cornutal patch a narrow elongate ribbon; large spines; dense cornutal patch on apical diverticulum; distal cornutus absent.
