( Fig. 20 )

LSID: urn:lsid:zoobank.org:act:E2579EAE-25EA-43DB-962D-4A70C590640C

Type specimen. Holotype: Female , East Madagascar, Marojejy massif (Integral Natural Reserve no. 12), alt. 2,050 m, 25-30 xi 1972, leg. A. Peyrieras; gen. slide no. CIS-7361 (in MNHN).

Diagnosis. This new species has a forewing pattern somewhat similar to that of the preceding new species ( T. sphenosa Park & Minet , sp. nov.) but it has a much larger wingspan with a smaller wedge-shaped costal patch, and its hind wing is grayish brown. The female genitalia of the two taxa are quite different from each other (cf. Fig. 19E and Fig. 20C ).

Description. Female ( Figs. 20A, B ). Wingspan, 22.0 mm. Head: brownish gray dorsally, with yellowish-white erect scales laterally.Antenna (broken in distal part); scape elongated, dark brown dorsally, yellowish white laterally; flagellum yellowish white, with brownish annulations. 2 nd segment of labial palpus thickened, with rough scales ventrally, slightly arched, yellowish brown in basal 2/3 and yellowish white beyond on outer surface; paler on inner surface; 3 rd segment slender, as long as 2 nd segment, strongly upturned, dark brown ventrally. Thorax: tegula and thorax dark brown dorsally. Forewing ground color dark brown; antemedian fascia yellowish white, subtriangular, broadened towards costa; apex angulate; termen concave medially; fringe narrow, yellowish white proximally; venation with R 5 to termen; M 2 and M 3 free; CuA 1 and CuA 2 stalked for basal 2/3. Hind wing grayish brown; apex angulate; termen sinuate; venation complete, M 3 and CuA 1 stalked for basal 1/3. Abdomen ( Fig. 20D ): spinose zones on terga well-developed, somewhat triangular.

Female genitalia ( Fig. 20C ): Apophyses anteriores about 2/3 the length of apophyses posteriores. Abdominal sternum VIII with a deep V-shaped notch at middle. Antrum weakly developed. Ductus bursae narrow in posterior 1/3, broadened medially, then slightly narrowed in anterior 1/3. Corpus bursae ovate, large, as long as ductus bursae; signum consisting of a long, Y-shaped, minutely scobinate plate (measuring about 4/5 the length of corpus bursae) and a small, pentagonal plate with hat-shaped sclerotized upper part.

Male unknown.
