Paratypes: 8 males, same locality ( MWM) ; 6 males, Myanmar (Burma), 25 km E Putao, env. Nan Sa Bon village , 800 m, 6−9.v.1998, leg. Murzin & Siniaev ( MWM) ; 1 male, Myanmar (Burma), Putao , 500 m, 27.iv.1998, leg. Murzin & Siniaev ( MWM) ; 1 male, Myanmar (Burma), 40 km N Myitkyina, Chanc Kand village , 236 m, 23−24.iv.1998, leg. Murzin & Siniaev ( MWM) .

Description. Length of fore wing 15 mm. Antenna short, bipectinate, setae in medium third of antenna twice longer than antenna rod diameter, thorax and abdomen from above covered with long brown scales, long modified scales on apex of abdomen. Fore wing light-brown with bright brown round spots along costal and lower edges and in discal cell, oblique band of small brown spots from top area of costal edge to medium third of lower edge; portions with long grey-white androconium scales cubitally (from base to postdiscal area), at base of radial veins and postdiscally. Hind wing light-brown with poorly developed blurred brown pattern. Fringe on all wings mottled, light between veins, brown at veins.

Male genitalia ( Fig. 18 ). Uncus wide, with extended semicircular bifurcation apically, apical halves of uncus diverge at a right angle, wide, short, apices of halves concave; scaphium and subscaphium fused into long spindle-like tube; gnathos arms short, lamellar; gnathos lamellar with long thin lateral processes; valve short with semicircular costal edge, saccular and outer edges slightly curved; saccular edge (in basal half) strongly sclerotized, tabulate, distally sharply cut, with pyramidal harpe directed dorsally; juxta lamellar, robust; saccus almost reduced; phallus 2.5 times shorter than valve, thick, in distal third with robust spiky cornutus directed distally.

Female unknown.

Diagnosis. The new species is most close to S. nepalensis , from which it differs in the clearly expressed androconium portions on the fore wing, the poorly developed postdiscal band on the fore wing, the concave halves of the uncus, and the saccular sclerotized edge which is distally sharply cut.

Distribution. Northern Myanmar (Kachin State).

Etymology. The new species is named after Ms. Htar Htet Htet − Former Myanmar beauty queen, who sided with the partisans against the military junta during the 2021 coup in Myanmar.
