Diagnosis. — The forewing ground color is lighter in S. apertura than in S. malagasy, and the hindwing is light brown (Fig. 217-218). The genitalia are similar.
Description. Adult Male. — Head: Basal segment of labial palpus black; median segment black with light brown apex; apical segment black, apex cream. Frons with short scales black and cream; long scales black and cream; lateral spots at eye margin absent; vertex black and cream. Antenna serrate; scape black and cream; flagellum cream.
Thorax: Patagium a mixture of fuscous and pale brown scales with a brown band at twothirds width bordered by white distal border, a brown lateral spot at one-third width. Basal twothirds of tegula light brown, brown to white at apex. Mesothorax light brown and white. Underside of thorax white. Prothoracic femur fuscous and white; tibia with lateral scale tufts not extending beyond first tarsal segment, cream and light brown, subapical spot pale fuscous; tarsal segment 1 cream, 2 fuscous and cream with cream apical ring, tarsal segments 3-5 fuscous. Mesothoracic femur brown and cream; tibia brown (with a few cream scales), inner spur less than twice length of outer spur, spurs completely scaled; tarsal segments fuscous with cream apical rings.
Metathoracic femur fuscous (with a few white scales); tibia fuscous and cream; tarsal segments fuscous with cream apical rings.
Forewing: Length, 12-16 mm; ground color brown; basal line black; R vein not a contrasting color; basal scale patch between R and Cu veins absent; basal half circle scale patch below Cu vein absent; antemedial line pale brown bordered by black, indistinct; 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 an oblique trapezoid, cream, with a brown center, bordered by thin black lines; reniform spot cream outlined in black, center light brown with a white median line; white scales along Cu vein from orbicular spot to junction of veins M3 and CuAl and down vein CuA2 to postmedial line; postmedial line black, indistinct, from just below costa to posterior margin, wavy (can consist of only a few scales); postmedian band undifferentiated; black scale patches in middle of cells R4 to CuA2, patch in R4 basal to other patches in postmedian area (can be reduced in size); subterminal line a light brown band bordered by white (can be bordered by cream); apex lacking a white patch; dark brown square spots along outer margin; fringe dark brown. Underside ground color pale gray; outer margin spots absent; reniform spot absent.
Hindwing: Ground color light brown; fringe white. Underside ground color white; costal cells C and Sc white speckled with gray scales; outer margin spots absent; no spot on underside.
Abdomen: Dorsum pale gray; venter brown and cream; disto-lateral black spots on sternites absent; 8th tergite with spiculate patches absent on caudal margin.
Genitalia: Uncus evenly curved; slender, gradually narrowing toward pointed apex; setae absent or few. Scaphium elongate, weakly developed. Tegumen lacking a pair of projecting arms on upper third. Costa slightly bent at middle
at base of costa on inner edge; perpendicular to costa of valve. Cucullus apex truncate; produced. Anellifer with lightly sclerotized plate bearing setae absent. Ampulla slender, elongate; apex pointed and hooked; curves along longitudinal plane of valve; extending beyond apex of valve (Figs. 315, 345). Clasper proper absent. Clavus a minute
round projection. 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 narrow rectangular band with ventrolateral-lateral projections, median process as wide as base, ventral margin straight with curved sides. 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 curving ventrally; moderately elongate, 0.75-1.0 length of aedoeagus; apicobasal cornutal patch quadrate; short, extending to just beyond apex of aedoeagus; cornuti in form of minute flat granules; lateral cornutal patch absent; dense cornutal patch subapical on vesica; distal cornurus an ovate plate with large spines at apex.
Adult Female. — Essentially as described for male except:
Forewing: Length, 16-17 mm.
Abdomen: Fine dense scales on 8th segment cream.
Genitalia: Ventral plate of ostium bursa with height greater than width; distal margin straight; ventrolateral invaginated pocket of 8th sternite absent. Ductus bursae short (length less than twice width); completely sclerotized. Appendix bursae partially sclerotized. Corpus bursae bulbous, length less than twice width; a few striae. Signum in apical half of corpus bursae; elongate, length greater than 1.15 mm; forming greater than a 45 degree angle to vertical axis of corpus bursae.
