Description
Antennae dark brown above, paler brown below, and yellow brown before club. Palpi with the second segment long and erect, densely covered with yellow brown scales ventrally; the third segment thin and pointed, prominently protruding. Wings upperside with ground color brown, forewing cell spots conjoined, lower one larger and produced toward base; spot in space CuA1 largest, spots in spaces M3 and R3-R5 small, spot in space CuA2 pale yellow; hindwing without spots. Forewing underside brown with dense yellow brown scales at costa and apex, a broad white area along dorsum distally; markings similar to those on upperside except for small spots in spaces M1 and M2; hindwing underside ground color yellow brown with ferruginous scales distally and a broad grey brown area along dorsum; subapical area with small white spots in spaces Sc+R1 to CuA2, of which in spaces M1 and M2 totally conjoined, forming a single larger spot, in spaces Rs and M3 dot-like; cell with two white small spots distally, upper one dot-like; all white spots surrounded by dark area.
Male genitalia (Figs. 70−74): Uncus longer than tegumen, triangular basally, thin and long distally; socius slender and pointed at tip; saccus long; valva with ventrodistal process rather rounded, armed with small spines apically; aedeagus with suprazonal sheath noticeably shorter than subzonal sheath; juxta funnel-like, thin and long basally, pointed at tip.
Distribution
China (Sichuan, Guangdong).
Remarks
Externally the new species is very similar to S. tytleri from Manipur, Assam (Evans, 1914; 1949), but can be distinguished from the latter by the following characters: forewing upperside with spot in space M3, underside with spots in spaces M1 and M2; valva with the ventrodistal process symmetrical distally. The new species also resembles S. parawoolletti, but can be distinguished from the latter by the combination of the following characteristics: forewing underside with small white spots in spaces M1 and M2; hindwing underside with white spots in discoidal cell, spaces Rs and M3; juxta with lower margin gradually narrowed; valva with ventrodistal process distally rounded.
Both S. tytleri and the new species are the members of a vicariant species group of woolletti in sharing lateral processes of the tegument which is a unique feature of the group in the genus.
