Diagnosis.
The male genitalia are similar to those of
T. cameroona
Park, 2018
(
Figs. 9
G–I), but can be distinguished from the latter by the ventral margin of valva deeply emarginated prior to lower corner of cucullus; cucullus broader and less elongated, with more oblique outer margin distally; juxta broader distally, with wider distance between caudal processes; aedeagus stouter; cornuti consisting of two adjacent, elongated bundles of short scales dorsally and a cluster of variable lengths of spines ventrally (
Fig. 9E
), unlike a bundle of long, hair-like scales in
T. cameroona
(
Fig. 9H
).
Description.
Male (
Figs. 9A, B
). Forewing length
7.5 mm
.
Head
: Vertex yellowish brown, with yellowish- white erect scales laterally. Antenna with basal segment elongated, slightly dilated distally; flagellum serrate, orange white, broken off beyond middle in both antennae. Second segment of labial palpus (
Fig. 9B
) thickened, sabershaped, orange grey, speckled with dark-brown scales on outer surface, dark brown dorsally; 3
rd
segment slender, strongly upturned, as long as 2
nd
segment, light orange, sharply pointed apically.

Thorax
: Notum and tegula yellowish brown. Hind tibia greyish orange white dorsally, with rough scales above. Forewing ground color yellowish brown, irregularly scattered with dark-brown scales; costa arched beyond 2/3, oblique to apex; apex slightly produced; termen oblique; fringe concolorous with ground color, with narrow, orangewhite basal line. Hind wing dark brown.
Abdomen
(
Fig. 9F
): A pair of long hair-pencils in segment VII; sternite VIII medially extended with a very slender, aristate, apically bifurcated stalk anteriorly; caudal arms directed outwardly. Male genitalia (
Figs. 9
C–E): Uncus slightly broadened distally, about 1/2 the width of basal plate of gnathos, with convex caudal margin, reach- ing caudal margin of basal plate of gnathos. Basal plate of gnathos with rounded caudal margin; median process broad at base, narrower toward apex, curved downward at nearly a right angle beyond 2/3, sharply pointed apically. Tegumen weakly sclerotized, deeply incised in V-shape medially on posterior margin and anterior margin. Valva slightly expanded in basal 1/4 of costa; cucullus densely setose, upturned, convex medially on ventral margin, with round apex. Juxta large, shield-shaped, with small triangular lateral processes; caudal margin convex; anterior margin with distinctly acute median process. Vinculum narrow, band-like. Aedeagus stout, shorter than valva, about 3/5 the length of valva, sharply produced apically; cornuti consisting of two overlapped leaf-like bundles of scales and a cluster of variable length of spines in distal 1/3.
Female unknown.

Etymology.
This species name is derived from a Korean word,

, meaning the Milky Way.
