( Figs. 13 A–G)

Type specimen. Holotype: male, Uganda, Kabarole District, Kibale National. Park, 36N TF 05626208 1500 m, 19– 24 x 2014, Leif Aarvik & Knud Larsen; gen. slide no. CIS-7230, COI barcode CBNU091, deposited in NHMO.

Diagnosis. The new species is characterized by having a distinct, large, triangular orange-white costal patch near 3/4 on the costa. The male genitalia are more or less similar to those of T. retusivalva , but they can be distin-

guished from those of the latter by the broadly developed uncus, the much larger caudal plate of the juxta, and the aedeagus bifurcate apically ( Figs. 13E , E’)

Description. Male ( Fig. 13A ). Forewing length 8.5 mm. Head: Dark brown, with light-yellow erect scales laterally. Antenna ( Fig. 13A ) serrate, about 4/5 the length of forewing; basal segment elongated, light yellow dorsally, dark brown ventrally; flagellum light yellow, with fine cilia ventrally, without annulations. Second segment of labial palpus thickened, saber-shaped; outer surface dark brown in basal 2/3 and orange white beyond; orange white on inner surface; 3 rd segment strongly upturned, as long as 2 nd segment, orange white dorsally, dark brown ventrally, acute apically.

Thorax: Dark brown dorsally. Tegula concolorous with thorax. Forewing densely scattered with dark brown; antemedian fascia well developed, large, with black scales; postmedian fascia broad, weakly developed; costa arched beyond costal patch; apex more or less rounded; termen oblique, slightly convex beyond middle; fringe concolorous with ground color, with narrow, orange-white basal and brown sub-basal lines; venation similar to that of the generic description. Hind wing greyish brown; with a hair-pencil at base.

Abdomen ( Fig. 13G ): Spinous zones on tergites broadly developed, with a pair of long hair-pencils between segment VII and VIII; sternite VIII short, broad with crescent anterior margin and slightly concave caudal margin. Male genitalia ( Figs. 13 C–F): Uncus broadened as wide as basal plate of gnathos, with nearly straight caudal margin, not exceeding apex of basal plate of gnathos. Basal plate of gnathos broad, with round caudal margin; median process broad at base, strongly curved downward beyond 2/3. Tegumen deeply emarginated medially on posterior margin, with converted V-shaped incision on anterior margin. Valva with costa slightly expanded anteriorly in basal 1/3, then concave; cucullus elongated, slightly upturned, with round apex, densely setose. Juxta large, broad at base and slightly narrowed caudally, with large triangular caudal plate and with small, triangular lateral lobes. Vinculum band-like, narrow, heavily sclerotized. Aedeagus slender, shorter than valva, bifurcate apically; cornuti consisting of a long, horn-shaped bar near middle of aedeagus, shorter than 1/2 the length of aedeagus and a shorter bar near apex, about 1/3 the length of the longer one.

Female unknown.

Distribution. Uganda (Kabarole Distr.).

Etymology. The species name is derived from the Korean term woori, meaning “we” or “together.”
