Description. Adult ( Fig. 12): Wingspan 8.5–10.0 mm. Head whitish yellow, leaden laterally, scale tuft behind compound eye grayish-yellow with black outer margin. Antenna with scape grayish-yellow; flagellum deep leaden dorsally, deep-yellow ventrally. Labial palpus grayish-yellow, distal half of second segment and entire third segment deep leaden ventrally. Thorax whitish yellow mottled leaden scales at middle. Tegula deep leaden, grayish-yellow along margins. Forewing whitish yellow, overlaid with black and brown spots, stripes and patches; costal margin with four black spots, the spot at base smallest, spots at 1/4 and 2/3 length larger; brown line from near base of fold arched upward and then extending along subcosta vein to second spot of first row; cell with an elliptical black spot at middle, with a round black spot at end; slender brown stripe along middle of cell on anterior margin, irregularly shaped dark-brown patch anterior to anterior corner of cell beneath; three black patches along above fold from basal 1/5 to 5/6, the third one at 5/6 smallest; beneath fold with three brown stripes; apex with a deep-brown spot; dorsum with a small black dot near base, with a large brown patch at 2/5 length; brown fascia from 2/3 length of costal margin to tornus, arched outward medially; termen brown; cilia whitish yellow mixed with brown. Hindwing and cilia deep-gray. Legs grayish-yellow except fore femur deep leaden on ventral surface. Abdomen brown dorsally except yellow at basal 1/4, whitish yellow ventrally.

Male genitalia ( Fig. 36): Brachia of uncus sclerotized, slightly curved; right brachium slightly longer than left one, hooked apically. Valva broad and short, rounded terminally, costa slightly concave, ventral margin straight; valvella finger-shaped, 3/4 length of valva, basal 3/4 uniformly wide, then gradually narrowed to apex, costal margin with a small process at 3/4 length. Anellus heavily sclerotized, gradually narrowed to roundly pointed apex, reaching 1/3 length of uncus brachium. Phallus slightly narrowed distally, coiled at middle, distal part membranous. Cornutus spine-shaped.

Female genitalia ( Fig. 55): Posterior apophysis about twice as long as anterior apophysis. Sterigma widely collar-shaped. Ductus bursae broad, slightly longer than posterior apophysis, crinkled longitudinally, with a large annular sclerite medially. Corpus bursae rounded, same length as ductus bursae; signa a pair of sclerotized stout teeth, with weakly sclerotized, irregularly shaped base.

Type material. Holotype ♂, INDONESIA: Mentawir River [1°03' N, 116°44' E], E. Borneo, Balikpapan, 50 m, x. [19]50, coll. A. M. R. Wegner, genitalia slide no. ZZWGW001 ( RMNH, Leiden). GoogleMaps  

Paratypes: 1 ♂, same data as for holotype GoogleMaps   ; 1 ♀, INDONESIA: S. Celebes, 50 m, Bantimurung, 9– 18.viii.1949, coll. A. Diakonoff and Manis, genitalia slide no. ZZWGW002 ( RMNH, Leiden)   .

Distribution. Indonesia.

Diagnosis. This new species resembles S. hongkongensis   sp. nov., but can be distinguished from it by the smaller size, the eighth segment in male without pleural lobes, which are present in S. hongkongensis   sp. nov.

Etymology. The specific epithet is derived from the Latin minutus = small, in reference to the small size of the species.
