(Figs. 1–12)
Description. Genearal coloration ochraceous, with reddish bands. Head with thin arcuate and piceous submargial band anteriorly, with transverse arcuate band between eyes, narrowly margined with piceous, orange red patch. Face with thin arcuate and piceous submarginal band. Pronotum with anterior orange and posterior submarginal brown transverse bands. Forewings ochraceous, with hyaline spots and piceous areas. Head including eyes slightly narrower than pronotum. Crown triangularly produced, distinctly longer medially than next to eyes, 0.8 times as long as width between eyes. Ocelli situated on anterior margin of crown, separated from eye by distance equal to its own diameter. Frontoclypeus narrow, nearly 1.6 times longer than width between antennal pits; transclypeal suture distinct. Anteclypeus slightly expanded apically, with apex following normal curve of genae. Lora almost as wide as anteclypeus basally. Pronotum approximately 1.4 times as long as crown; lateral margin carinate; anterior margin roundly produced; posterior margin slightly concave. Scutellum nearly as long as pronotum, with transverse suture slightly curved and prominent.
Second sternal apodeme in male with posterior lobes long and well developed, convergent distally, reaching 4th sternite.
Male genitalia. Pygofer slightly longer than wide in lateral view, apparently extended beyond apex of subgenital plates, with numerous long macrosetae in distal half; hind margin subobliquely rounded. Subgenital plates strongly tapering in apical 1/3 to narrowly rounded apex, with a lateral row of stout macrosetae and additional hair like setae. Styles approximately 2.7 times as long as wide basally; preapical lobe prominent, with setose hairs; apophysis gently tapered to narrowly rounded apex. Connective Y-shaped, with arms nearly twice longer than stem, produced lobe-likely on dorsal side in lateral view. Aedeagal shaft slender, wider at base, nearly twice longer than connective, pointed apically, gently curved at distal 1/ 3 in lateral view; gonopore subapical, on dorsal side.
Female genitalia. Posterior margin of abdominal sternum VII deeply concave, with dark patch and slender triangular projection medially.
Body length. Male 4.6-4.7mm; female 4.9-5.0mm.
Type material. Holotype, male, Korea, Jeonbuk Province, Naejangsan, 14.VIII.1981, coll. Y.J. Kwon. Paratypes: 1 female, same data as holotype; 1 female, Gyeongbuk Province, Palgongsan, 23.IX.1984; 1 female, Gyeonggi Province, Gwangneung, 12.VIII.1994, all same collector.
Host plant. Unknown.
Etymology. The name of the species is derived from the locality of the holotype.
Remarks. This new species resembles Scaphomonus indicus (Distant) but can be readily differentiated from the latter by the shape of the subgenital plates and aedeagal shaft.
