Type material. Holotype: female, LAOS: Bolikhamsai Prov., Phou Khao Khouay National Protected Area , 18°23’42’’N 103°04’ 1’’8E, 470 m, 10 xi 2015, leg. YS Bae, BS Park, SM Na, JW Kim, & DJ Lee; gen. slide no. CIS-8087 . Paratypes: 1♀, same locality as holotype, 18°27’23’’N 103°03’0’’5E, alt. 479 m, 26 vii 2019, leg. YS Bae, MJ Qi, DJ Lee, TG Lee, YB Cha, JH Ko, & CM Jang; gen. slide no. CIS-8094 ; 1♀, CAMBODIA: Kep Prov., Kep, Spring Vall. Lodge, 4-6 v 201, leg. J. Heppner; gen. slide no. CIS-8100 .

Diagnosis. This new species is superficially similar to the preceding new species, T. cordisigna sp. nov., but it can be distinguished by the darker forewing ground color having a more distinct wedge-shaped costal patch, fringe with no yellowish–white basal line nor white scales apically; and the forewing venation with R 3 stalked for basal 1/3. The female genitalia can be distinguished from any known species of the genus by having two zones with numerous spines in the corpus bursae.

Description. Female ( Figs. 6 A-C). Wingspan 14.0 mm. Head: Dark yellowish brown dorsally, with yellowish white scales laterally. Antenna slightly longer than forewing; basal segment dilated distally, dark brown dorsally and ventrally, yellowish white on anterior and posterior surface; flagellum yellowish white, with dark-brown annulations. Second segment of labial palpus thickened, arched, dark yellowish brown in basal 3/4 and yellowish white in distal 1/4 with distinct dark-brown ring preapically; yellowish white on inner surface; 3 rd segment, slender, strongly upturned, longer than 2 nd segment, yellowish white, dark brown ventrally. Thorax: Tegula and thorax yellowish white dorsally. Hind tibia with yellowish-white rough scales above and creamy-white scales at apex. Forewing ground color dark yellowish brown evenly, with a small wedge-shaped, yellowish-white costal patch before 3/4 of costa; apex obtuse; termen concave beyond apex; fringe concolorous with ground color, without white basal line; venation with R 1 arising from near middle; distance between origins of R 2 and R 3 less than 1/2 the length of R 1 and R 2; R 3 and R 4 stalked for basal 1/3; R 4 and R 5 stalked beyond distal 1/4; M 2 much nearer to M 3; CuA 1 and CuA 2 stalked for basal half; cell weakly closed. Hind wing pale brownish gray, broader than forewing; venation with M 3 and CuA 1 short-stalked; cell closed; apex acute; termen sinuate; fringe concolorous with ground color.

Female genitalia ( Figs. 6 D-F): Apophyses anteriores about 3/5 the length of apophyses posteriores. Abdominal sternite VIII deeply emarginated in U-shape medially; lateral corner on anterior margin sharply produced laterally. Antrum membranous, funnel-shaped. Ductus bursae narrow, shorter than the length of corpus bursae; ductus seminalis arising from near middle. Corpus bursae extremely large, ovate, with two series of unique spine-like scales posteriorly; signum heart-shaped, with strong spines along heavily sclerotized posterior margin; numerous conic spines on surface’ deeply incised on anterior margin.

Male unknown.

Distribution. Laos (Bolikhamsai), Cambodia (Kep).

Etymology. The species name is derived from the Latin, multus (= abundant) and spina (= thorn), referring to numerous thorn-like spines in the corpus bursae of the female genitalia.
