Type specimen. Holotype: Male, [East Madagascar], [Integral] Natural Reserve no. 3 [Zahamena National Park], Andranomalaza, Ivelona valley, x [19]57, leg. P. Soga; gen. slide no. CIS-7369 (in MNHN) . Paratypes: 2♁, same data as holotype; gen. slides nos. CIS-7368, -7382 (in MNHN) .

Diagnosis. This new species is similar to the following new species, T. vietteiola sp. nov., but it can be distinguished by the following traits of its forewing venation: M 2 and M 3 nearly connate at base; CuA 1 and CuA 2 stalked for basal half (whereas, in T. vietteiola , M 2 is remote from M 3 proximally and CuA 1 and CuA 2 are stalked for basal 2/3). Moreover, the hind tibia has dark-brown rough scales before half and in distal 1/4 dorsally, whereas, in T. vietteiola , it has dark fuscous rough scales ( Fig. 8D ).

Description. Male ( Figs. 7A–D ). Wingspan, 14.0 mm. Head: brownish orange dorsally, with yellowish white, erect scales laterally. Antenna (broken away in distal part); scape elongated, pale orange all around; flagellum pale orange, without annulations. 2 nd segment of labial palpus thickened, arched, yellowish brown on outer surface; 3 rd segment slender, as long as 2 nd segment, slightly upturned. Thorax: tegula and thorax yellowish brown dorsally. Hind tibia with brownish orange rough scales before half and in distal 1/4 dorsally ( Fig. 7D ). Forewing ground color bronze brownish orange; antemedian fascia pale orange, followed by pale-orange suffusion in upper 1/3; costal patch small, wedge-shaped, pale orange; venation with R 1 arising from about 2/5 length of discal cell, nearly straight from base; distance between R 1 and R 2 at base about twice length of R 2 and R 3; R 3 stalked with R 4+5 for about basal 1/4; R 4 and R 5 stalked; R 5 termen; M 1 close to R 3+4 at base; M 2 and M 3 nearly connate, arising from lower corner of cell; CuA 1 and CuA 2 stalked for basal half; cell weakly closed; apex angulate; termen oblique. Hind wing ground color similar to that of the forewing; one vein absent, M 3 and CuA 1 being coincident; M 2 and M 3 +CuA 1 nearly connate; cell weakly closed. Abdomen ( Fig. 7H ): bronze brownish orange dorsally; spinose zones weakly developed anteriorly.

Male genitalia ( Figs. 7E–G ): Uncus bifurcate, with thumb-like latero-caudal processes directed outwardly, slightly going beyond caudal margin of basal plate of gnathos; apex rounded. Basal plate of gnathos broad, fanshaped with convex caudal margin; median process somewhat long, slightly bent apically. Tegumen weakly sclerotized. Valva broad at base; costa deeply concave; ventral margin emarginated before lower corner of cucullus; cucullus thumb-shaped, with rounded ventral margin, slightly upturned, densely setose; apex angulate. Juxta large, deeply concave on caudal margin; latero-caudal processes thumb-like. Aedeagus extremely stout, broader than base of valva, bifurcated in apical 1/4, with large fan-shaped ventral plate and dentate on dorsal surface; cornutus a large sac containing numerous minute conical spines.

Female unknown.

Distribution. Madagascar (eastern region).

Etymology. The species name is in honour of Pierre Soga who was a Malagasy forest ranger and famous insect collector.
