Diagnosis. Wing pattern of this new species is similar to S. melanobasis (Hampson, 1906) from Japan. But it can be distinguished from the latter by the broad uncus and juxta, and short spinate cornutus in the phallus. In S. melanobasis, the uncus is elongated, U-shaped juxta and phallus has a long spinate cornutus (Kim et al. 2021).
Description Adult (Figs. 1A & B). Length of the forewing 8.0−9.0 mm in male. Head covered with grayish-brown scales; labial palpus slender, upturned, covered with grayish-brown scales.Thorax grayish-brown, mixed with dark brown scales. Ground color of forewing grayish-brown, with dark brown basal area; pale medial area with two dark brown spots at costal margin; orbicular stigma dark brown; postmedial line dark brown, undulated; distal area grayish-dark brown; adterminal line dark brown; terminal line ivory; fringe ivory, mixed with dark brown. Ground color of hindwing grayish brown; marginal shade dark brown; indistinct postmedial line dark brown. Abdomen light brown, with a subquadrate dark brown spot at 2 nd tergite. Male genitalia (Figs. 2A & B). Uncus broadly rectangular, with hairs. Gnathos joined distally, hooked at apex. Valva elongated, angularly curved inwardly, with hairs along outer margin. Vinculum U-shaped. Saccus narrowly U-shaped, about half as short as uncus. Juxta broadly ovate, weakly sclerotized. Phallus elongated, slightly curved, about 1.5 times longer than valva, with a short spinate cornutus. Female genitalia. Unknown.
Etymology. This species name is dedicated with gratitude to Dr. Jae-Shin Kang, project manager (the Global Research Project II-2) of National Institute of Biological Resources (NIBR), who contributed to the collection of Laotian specimens.
