( Figs. 1–11 )

Description. General coloration whitish yellow with patchy orange patterns on crown, pronotum and scutellum. Coronal suture not distinctly visible, with 2 orange spots between posterior margin of crown and anterior margin of pronotum. Face shiny, without conspicuous spots or streaks; rostrum orange. Eye dark brown. Pronotum with two longitudinal orange stripes, and irregular orange patterns on lateral margins. Scutellum with two irregular orange stripes; scutellar suture prominent. Forewing without brown or castaneous band and orange stripe like other species of this group, but two small dark brown spots on 2nd and 4th apical cells. Hindwing hyaline. Leg and body venter whitish yellow. Second sternal apodeme in male with posterior lobes small, round apically, extended up to middle of 3rd sternite.

Male genitalia. Pygofer lobe elongate, broad basally, roundly convex at posterior margin with pointed and slanting downwards posterior angle, numerous setae on near to ventrocaudal surface. Subgenital plate with 4 long macrosetae and row of short rigid setae at upper margin subbasally. Style long with narrow base, with prominent preapical lobe, widened and pointed apex. Connective Y-shaped, short base, with long narrow branches diverging on wide arc. Aedeagal shaft straight, long and tubular, strongly bent laterad with two apices in lateral view; dorsal apodeme short, moderately expanded, with pair of process arising from basolateral part of shaft, subapically bent recurringly; gonopore apical.

Length. Males 2.6−2.9 mm, females 2.6−2.9 mm.

Type material. Holotype male, Korea, Chungbuk Province: Mt. Cheondeungsan , on Quercus sp., 1.X.2016, Y.J. Kwon ; Paratypes, 2 males and 3 females, same data as holotype .

Distribution. Korea (Central).

Host plant. Quercus sp.

Etymology. The specific name is derived from name of the mountain of type locality.

Remarks. This species differs from other species in lacking a castaneous brown or orange stripe on the forewing. Its male genitalia are similar to Naratettix ibukisianus but differ from the latter by the characteristic tip of the aedeagal shaft and position of the basolateral process.
