Type material. Holotype: ♂, THAILAND, Chanthaburi, Phliu, ca. 200 m, 4.vi.1983, coll. Kuroko, Moriuti, Arita, and Yoshiyasu, gen. slide No CIS-6380/Park. Paratypes: 1♂, same data as the holotype, gen. slide No CIS-6391/ Park; 3♂, Ban Trok Nong, ca. 200 m, 5.vi.1983, coll. Kuroko, Moriuti, Arita, and Yoshiyasu, gen. slide No. CIS- 6377/Park; 2♂, 1♀, THAILAND, Loei, Phu Rua, 15-19 viii 1987, CIS-6390/Park (♀), CIS-6393/Park (♂). Types are deposited in KNA, Korea, on indefinite loan from the original country.
Diagnosis. This species is superficially similar to the preceding new species, T. multispina , by having a slender 3rd segment of the labial palpus ( Fig. 7 View FIGURES 3 – 8 a), but it can be distinguished by its smaller size, with more distinct yellow costal patch beyond 2/3 of costa and with darker distal area of wing beyond second discal stigma. The male genital character differs from that of the above two species by having a small spine at middle of the ventral margin of the valva (indicated by an arrow in Fig. 16 View FIGURES 15 – 17 a); juxta with large nipple-shaped postero-lateral lobes; phallus with 9–10 strong, similar length spines directed posteriorly in the same way ( Fig. 16 View FIGURES 15 – 17 b).
Description. Adult ( Fig. 7 View FIGURES 3 – 8 ). Male. Wingspan 9.0–9.5 mm. Head with orange-white appressed scales on vertex; lateral raised tufts brown; frons pale orange white. Antenna about 4/5 length of wing; scape elongate, dark brown dorsally, without pecten; flagellum with dark-brown annulations in basal 4/5, with distinct notch at 1/5 length, orange white in apical 1/5. Male with 2nd segment of labial palpus thickened, slightly recurved, orange white all around, with long, dark-brown scale tuft in apical 1/3 above, length of tuft about 2/3 length of 2nd segment; 3rd segment shorter than 2nd segment, thickened basally, then narrower toward apex, with smaller scale tuft basally, gray, speckled with dark-brown scales dorsally; apex white, acute. Tegulae and thorax dark brown, more black scales along caudal margin. Forewing elongate; ground color gray, speckled with dense dark-brown scales; costa with yellow suffusion beyond 3/4; subbasal fascia poorly developed, black; two black discal stigmata well developed: first one rounded, near middle of discal cell, expanding to large black antemedian fascia which triangularly extends to hind margin of wing; second stigma large, elliptical, at end of cell; distal area beyond this second discal stigma densely covered with black scales; apex obtuse; termen oblique; fringe dark gray, basal 2/5 darker; venation similar to that of the preceding new species. Hindwing gray, narrower toward apex; apex acute; fringe gray; venation also similar to that of the preceding new species. Hind tibia clothed with long hairs above, dark brown in basal 1/3 and apical 1/4, pale yellow medially on outer surface; orange white on inner surface; first segment of tarsi orange white in basal 1/3, then with black scales beyond.
Male genitalia ( Fig. 16 View FIGURES 15 – 17 ). Basal lobes of uncus rectangular, broadly expanded laterally, concave at middle on caudal margin. Median process of gnathos narrowed beyond half, with more sharply acute apex, hooked. Costal bridge broad, connecting valva and base of tegumen, not angled medially. Valva ( Fig. 16 View FIGURES 15 – 17 a) with more or less shortened cucullus obtuse at apex; costa slightly convex medially, then slightly concave before apex; ventral margin deeply concave medially, with a small spine-like process beyond (indicated by an arrow in Fig. 16 View FIGURES 15 – 17 a); sacculus broad in basal 1/4 length of ventral margin, narrowed, then slightly widened to median ventral spine. Juxta deeply concave on posterior margin, with large nipple-shaped caudal lobes. Vinculum broadly developed anteriorly. Phallus ( Fig. 16 View FIGURES 15 – 17 b) stout, shorter than valva; cornuti consisting of 6–7 strong, similar sized conic spines, directed posteriorly.
Female genitalia ( Fig. 22 View FIGURES 21 – 23 ). Abdominal sternite VIII emarginate at middle on caudal margin, with digitate process on anterior margin laterally. Apophyses anteriores less than 1/2 length of apophyses posteriores. Ductus bursae very short, about 1/3 length of corpus bursae, with conic spines on internal surface in distal half. Corpus bursae ovate, having numerous short, cone-shaped spines in distal half; accessory bursa very broad basally, about 1/2 width of corpus bursae, arising laterally from middle of corpus bursae, then narrowed; signum small, rounded, denticulate, placed anteriorly.
Distribution. Thailand (Chanthaburi)
Etymology. The specific name is derived from the type locality, Phliu.
