Description. Adult (Figs. 1 e, 2e): Wingspan 14.0–18.0 mm. Head dark gray, frons yellowish white. Antenna yellow, scattered with dark brown scales on outer surface. Labial palpus yellow; male first segment short, second segment long, slightly outward widened medially, pointed terminally, about twice length of first segment; female second segment slightly thick, third segment slender, a little longer than second, pointed terminally. Thorax and tegula yellowish brown, scattered with brown scales. Forewing with costal margin straight, apex bluntly rounded, termen oblique; ground color yellowish white except termen blackish brown with scattered brown scales; cell-dot blackish brown, small, nearly rounded; discocellular spot blackish brown, relatively large, short claviform; tornal stripe obliquely inward, nearly joined with discocellular spot; cilia yellow. Hindwing gray; cilia concolorous. Fore and mid legs yellowish white on dorsal surface, yellowish brown on ventral surface, tarsi with narrow yellow bands; hind legs pale yellow, tarsi with brown and yellow stripes.
Male genitalia (Fig. 3 e): Uncus nearly semicircular, slightly concave at middle on caudal margin. Gnathos with basal 2/3 relatively broad, distal 1/3 conspicuously tapering to apex. Costal bridge narrow, triangularly widened at basal 1/3. Valva with basal 1/3 relatively broad, nearly parallel dorso-ventrally medially, distal 1/3 slightly widened to blunt apex; sacculus long, about 2/3 length of valva, with hard hairs at middle on ventral surface. Juxta large, anterior margin protruded medially, apex blunt; caudal margin deeply split in middle, postero-lateral lobes large, semicircularly concave laterodistally, straight terminally. Vinculum triangularly extended anteriorly. Aedeagus a little longer than valva, basal 1/3 slightly dilated, distal 2/3 nearly uniform, with numerous small teeth at about basal 1/4, with two sclerotized irregular plates medially, and with two slightly curved spicules distally.
Female genitalia (Fig. 4d): Apophyses posteriores about 2.5 times length of apophyses anteriores, nearly extended to anterior margin of abdominal sternite VIII. Lamella antevaginalis nearly rectangular, slightly sclerotized. Antrum inconspicuous. Ductus bursae long, about twice as long as corpus bursae, basal half with a long sclerotized belt, its distal half membranous, corrugated; ductus seminalis arising from middle of ductus bursae, roundly dilated basally, then sharply shrunk to apex. Corpus bursae rounded; signum placed anteriorly, small, irregularly rounded, with teeth.
Diagnosis. This species is similar to S. idiogena, but can be distinguished by the male labial palpus with the second segment pointed terminally; the juxta with postero-lateral lobes semicircularly concave laterodistally, straight terminally in the male genitalia. In S. idiogena, the male second segment of the labial palpus is expanded terminally; the postero-lateral lobes of the juxta are arched outward laterally and pointed terminally.
Distribution. China (Guangxi).
Etymology. The specific name of this species is derived from the Latin longi- (long) and zonalis (zonary), in reference to the long sclerotized belt in basal half of the ductus bursae.
