Description ( Fig. 1 ). Wingspan 11-12 mm. Antenna gray-brown, bipectinate in male, rami short. Head pale gray; frons dark brown; labial palpus dark brown, slender, upturned over vertex. Thorax dark brown. Patagium and tegula pale gray. Femur and tibia of forelegs mixed with fuscous and gray; tarsus fuscous. Midlegs with femur fuscous; tibia mixed with fuscous and gray, a pair of spurs in middle part (one short, another one long); tarsus fuscous. Hindlegs with femur gray; tibia gray, with a pair of spurs in middle part (one short, another one long) and a pair of spurs in apical part (one short, another one long); tarsus gray. Ground color of forewing pale gray, with antemedian series of three dark spots curved; straight medial dark band broad, rectangular at costa; one dark discoidal spot; postmedian series of dark spots curved outward; before apex with one fuscous patch; terminal series of dark spots; fringe fuscous gray. Hindwing dark gray; fringe gray.

Male genitalia ( Fig. 8 ). Uncus slender, bent with small spine at tip; valva knife-shaped with weakly setose, apex obliquely truncated, lower angle with one slim gap; costa with one shallow angular projection at half of costa; saccular process short, about 2/3 length of valva, with waved, slender spine, reaching to half of slim gap; juxta with heart-shaped apical part, bottom flat; aedeagus vesica with one spine-shaped cornutus, and bundle of small spines and four additional spine-shaped cornuti.

Female genitalia. Unknown.

Diagnosis. This species is superficially similar to S. pectinata Holloway , but it can be distinguished from the latter by the medial dark band slightly waved, and broader than that of S. cambodiensis , with triangular at costa, and fuscous gray hindwing. The male genitalia are similar to those of S. muara Holloway , but it can be distinguished from the latter by the apically rounded valva, with marginal, straight, subapical spine, and by the sinuous spine of saccular process reaching to the distal end of the subapical spine.

Distribution. Cambodia (Cardamom, Koh Kong, Seima).

Etymology. The species is named from the type locality country ( Cambodia).
