Type material. Holotype: ♂, THAILAND: Nakhon Nayok: Khao Yai, 800 m,. 9.viii.1987, coll. Moriuti, Saito, Arita, and Yoshiyasu, genitalia (=gen.) slide No. CIS-6381/Park. Paratypes: 2♂, same locality as holotype, 22.vi.1983, coll. Kuroko, Moriuti, Arita, and Yoshiyasu; 1♀, same locality as holotype, 22.vi.1983, coll. Kuroko, Moriuti, Arita, and Yoshiyasu, gen. slide No. CIS-6382/Park; 1♀, same locality as holotype, 21.vi.1983, coll. Kuroko, Moriuti, Arita, and Yoshiyasu, gen. slide No. CIS-6389/Park; 1♂, same locality as holotype, 22.ix.1987, Moriuti, Saito, Arita, Yoshiyasu; 1♂, same locality as holotype, 700m, 29.ix–6.x.1984, Karsholt, Lomboldt, Nielsen, gen. slide No. CIS-6384/Park. Types are deposited in KNA, Korea, on indefinite loan from the original country.
Diagnosis. This new species is superficially similar to T. pansarista , but it can be distinguished by having a slender, longer 3rd segment of the labial palpus in the male, whereas that of T. pansarista is broadly flattened, nearly triangular, and shorter than the 2nd segment. It can also be distinguished from T. crocosema by the phallus with different arrangement of cornuti: four much shorter spines in dorso-posterior part, four middle-sized ones ventrally, and longer 3–4 cornuti directed anteriorly, whereas in T. crocosema all of the cornuti are directed anteriorly.
Description. Adult ( Fig. 6 View FIGURES 3 – 8 ). Male. Wingspan 12.0–13.0 mm. Head with brown appressed scales on vertex; lateral raised scale-tufts dark brown; frons pale orange white, shiny. Antenna about 4/5 length of wing; scape elongate, dark brown, without pecten; flagellum dark gray, with dark-brown annulations, except orange white in apical 1/10, with well-developed notch at 1/5 length. Male with first segment of labial palpus ( Fig. 6 View FIGURES 3 – 8 a) about 1/3 length of 2nd segment, speckled with dark-brown scales outwardly; 2nd segment yellowish orange all around, with long, shiny dark-fuscous scale tuft dorso-apically, about 2/3 length of 2nd segment; 3nd segment as long as 2nd segment, dark brown, stout at base, then narrowed toward apex, apical part white dorsally, with sharply pointed apex. Forewing elongate; ground color gray, dense dark-brown scales evenly scattered; costa with yellow suffusion beyond 3/4; two black discal stigmata well-developed: first stigma large, before middle of cell, often extended to black, broadly expanded antemedian fascia; second one at end of discal cell, rounded, smaller than first one, broadly extended to postmedian fascia; apex obtuse; termen oblique; fringe dark gray, with black lines at basal 1/3 and 2/3; venation with R1 arising from middle of cell; distance between R1 and R2 about twice length of R2 and R3 at base; R3 and R4+5 stalked for 1/3 length of R3; R4 and R5 stalked beyond middle; R5 to termen. Hindwing gray, narrowed toward acute apex; fringe gray; venation with Rs and M1 stalked before middle; M2 and M3 coincident, close to CuA1 at base. Mid tibia dark brown on outer surface, with long hairs ventrally, yellow in apical 1/4; hind tibia dark brown on outer surface, with broad yellow band medially and apically, with long hairs dorsally and ventrally; first tarsus yellow in basal half and dark brown beyond.
Female antenna without notch in flagellum; 3rd segment of labial palpus normally slender; no other characters separable from male.
Male genitalia ( Fig. 15 View FIGURES 15 – 17 ). Basal lobes of uncus broadly concave on caudal margin. Median process of gnathos moderate, with sharply acute apex, hooked. Tegumen somewhat diamond-shaped, with nearly straight lateral margin medially. Valva ( Fig. 15 View FIGURES 15 – 17 a) with broad costal bridges connected to base of tegumen, not angled medially; basal portion broad, with proximal width more than three times that of median portion; cucullus more or less sickle-shaped, sharply pointed apically, gently concave on dorsal margin, ventral margin expanded outwardly beyond middle; sacculus elongate, terminated at middle of ventral margin of valva. Juxta shield-shaped, deeply concave on caudal margin, roundly protruded antero-medially; postero-lateral lobes small, nipple-shaped. Vinculum broadly rounded anteriorly. Phallus ( Fig. 15 View FIGURES 15 – 17 b) very stout, longer than valva; cornuti consisting of spines of different length: four small spines, three similar in length and one very short, three medium sized spines directed to dorsal surface beyond middle, 4–5 longer spines at middle, directed to base, and one stronger directed to apex.
Female genitalia ( Fig. 21 View FIGURES 21 – 23 ). Anterior margin of abdominal segment VIII heavily sclerotized, nearly flat on caudal margin. Apophyses anteriores about 1/2 length of apophyses posteriores. Ostium bursae broadly open. Ductus bursae membranous, relatively narrow; anterior half broadened, membranous, with a few conic spines. Corpus bursae elongate, twice as long as ductus bursae, bearing numerous, small conic spines on internal surface throughout; accessory bursae arising from middle of corpus bursae, narrower and shorter than corpus bursae; signum small, elliptical plate with dense denticles on surface, located anteriorly
Distribution. India (Southern part: Mt. Harriet, S. Andamans); Thailand (Southern part: Nakhon Nayok, Khao Yai Nat. Park).
Etymology. The specific name is derived from Latin multus (= many) and spina (= spine), referring to the numerous spine-like cornuti in the phallus.
