Diagnosis. The new species is distinguished from any known species of the genus by the forewing pattern, with broad, orange-white to pale orange median fascia. It is similar to the next species T. elgozmanyi sp. nov. in the forewing color pattern, but it is much smaller with a wingspan of 16.0 mm. (22.0 mm. in T. elgozmanyi sp. nov.), and it can be easily distinguished by the male genitalia with a longer uncus, the narrowly elongated cucullus distally, and the abdominal segment VIII, lacking the modified long rods anteriorly.

Description. Male ( Figs. 1A, B View FIGURE 1 ). Wingspan 16.0 mm. Head: Pale yellowish brown dorsally. Antenna slightly shorter than forewing; basal segment elongated, yellowish white, speckled with dark brown scales; flagellum shiny, yellowish white throughout, without annulations, shortly ciliate. Second segment of labial palpus ( Fig. 1C View FIGURE 1 ) thickened, slightly arched ventral margin, dark brown in basal half, yellowish white beyond on outer surface, yellowish white on inner surface; 3 rd segment slender, strongly upturned, slightly shorter than 2 nd segment.

Thorax: Tegula and thorax yellowish brown dorsally. Hind tibia not roughly scaled, with yellowish brown more or less appressed scales dorsally. Forewing with dark brown area in basal 1/3, outer margin slightly convex; antemedian fascia broad, yellowish white; area between antemedian fascia and postmedian fascia narrower than width of postmedian fascia; postmedian fascia broad, concave on inner margin; scattered with yellowish brown scales; costa arched beyond 3/4; apex obtuse; termen slightly convex medially; fringe yellowish brown, with narrow, yellowish white basal line; venation with distance between R 1 and R 2 more than 2.5× than that of R 2 and R 3; R 3 stalked with R 4 for basal 2/5; R 5 absent; M 1 remote from R 3+4 at base; M 2 well-developed; M 3, CuA 1, and CuA 2 on common stalk; distance between M 3 and CuA 1 shorter than that of CuA1 and CuA2; 1A+2A nearly not forked at base; cell weakly closed. Hind wing ground color yellowish white, scattered with yellowish brown scales in basal half; venation with M 2 absent; M 3 and CuA 1 nearly connate at base; cell closed. Abdomen ( Fig. 1G View FIGURE 1 ): Spinose zones on dorsal surface broadly developed; tergite VIII with large, heavily sclerotized, crescent sclerite along anterior margin; sternite VIII extended into quadrate plate anteriorly with short, laterocaudal lobes directed outwardly.

Male genitalia ( Figs. 1 View FIGURE 1 D–F): Uncus broadened distally, narrowed at middle, with truncate caudal margin. Basal plate of gnathos broadly developed, fan-shaped, with round caudal margin. Tegumen sclerotized, incised into inverted V-shape on anterior margin. Valva with costa nearly straight basally, then abruptly oblique, deeply concave; ventral margin nearly straight to lower corner of cucullus; sacculus not developed; cucullus elongated, foot-shaped, densely setose, expanded outwardly around lower corner. Juxta broad. Vinculum narrowly banded. Aedeagus slender, shorter than valva, narrowly produced, sclerotized on dorsal surface; cornutus a row of minute spinules apically.

Female unknown.

Distribution. Uganda (Kabale District).

Etymology. This species’ name is derived from a Korean term “ onsemiro ”, meaning natural.
