Description ( Fig. 2View FIGURES 1 – 7). Wingspan 12-13 mm. Antenna gray-brown, bipectinate in male, rami short. Head pale gray; frons dark; labial palpus dark, slender, upturned over vertex. Thorax dark gray. Patagium pale gray and tegula fuscous gray. Femur, tibia and tarsus of forelegs dark gray. Femur of midlegs with fuscous gray; tibia dark gray, a pair of spurs in middle part (one short, another one long); tarsus dark. Hindlegs with femur gray; tibia pale 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); tibia fuscous. Ground color of forewing fuscous gray, with antemedian series of three dark spots curved; straight medial dark band broad, diffuse distally; one dark discoidal spot; postmedian series of dark spots convex outward, finished before costa and dorsum; before apex with one fuscous patch; terminal series of dark spots; fringe fuscous brown. Hindwing fuscous gray; terminal line dark; fringe gray.

Male genitalia ( Fig. 9View FIGURES 8 – 13). Uncus slender and bent, with a small spine at tip; valva with weakly setose, apex obliquely truncated, left valva narrower than right one, upper angle of left valva with sclerotized seta, lower angle of left valva sclerotized, distinctly angled; upper angle of right valva rounded, with seta (shorter than left valva) below apex, lower angle of right valva sclerotized, distinctly angled; costa with one shallow angular projection at half of costa; saccular process long, extend into lower angle of valva, with bent, spine-shaped projection at apex; juxta broad; aedeagus vesica with scobinate zone, one large and spine-shaped cornutus, one bundle of short spines, and finely scobinate.

Female genitalia. Unknown.

Diagnosis. This species is superficially similar to S. mlcochi Bucsek  , but it can be distinguished from the latter by the forewing with a medial dark band broad at costa; postmedian series of dark spots sharply curved outwardly, and gray hindwing. The male genitalia are similar to those of S. chinesica (Draudt)  , but it can be distinguished from the latter by the valva narrow, straight, apically tapering into a spike; the costa without a strongly angular projection at middle of costa; the aedeagus with one stout, spine-shaped cornutus, fused laterally with an oval plate.

Distribution. Cambodia (Bokor, Cardamom, Koh Kong, Samkos).

Etymology. The species is named from the Khmer ethnic group of Cambodia.
