LSID: urn:lsid:zoobank.org:act:EA01B193-9A17-48BD-A7F6-74753C7E6D81

Type specimen. Holotype: Female , East Madagascar, road to Anosibe [Anosibe An’ala] at km 57, 15 ii 1955, leg. P. Viette; gen. slide no. CIS-7397 (in MNHN).

Diagnosis. The forewing pattern of this new species is similar to that of T. nixcrinis Park, 2022 (described from Tanzania) by having a wedge-shaped, yellowish-white costal patch and entirely creamy-white fringe from apex to tornus, but T. anosibensis can be distinguished from the latter by a larger size ( T. nixcrinis having a wingspan of only 10 mm in), the head with yellowish-brown scales and the hind tibia with brownish scales dorsally (whereas, in the latter, the head has whitish scales and the hind tibia is creamy white in distal half). The signa of the female genitalia are quite different in the two species.

Description. Female ( Figs. 17A, B ). Wingspan, 18.0 mm. Head: bronze yellowish brown dorsally, with yellowish-white erect scales laterally.Antenna slightly longer than forewing; scape bronze yellowish brown dorsally, yellowish white laterally; flagellum yellowish white, without annulations. 2 nd segment of labial palpus ( Fig. 17B ) thickened, slightly arched, evenly bronze yellowish brown on outer surface, yellowish white on inner surface with dark-brown scales along upper and lower margins, with yellowish-white apex; 3 rd segment strongly upturned, as long as 2 nd segment, yellowish white laterally, dark brown ventrally, with sharply pointed apex. Thorax: thorax and tegula bronze yellowish brown. Hind tibia (removed). Forewing slightly broadened distally; costa nearly straight; ground color uniformly bronze yellowish brown, with a small, wedge-shaped, yellowish-white costal patch just before 3/4 of costa; apex angulate; termen oblique; fringe dark brown in proximal 1/3, then uniformly creamy white from apex to tornus. Hind wing broader than forewing, with similar ground color; venation with base of M 2 close to M 3 +CuA 1; M 3 merged with CuA 1. Abdomen: bronze yellowish brown dorsally, except on tergum VIII, which has yellowish-white scales.

Female genitalia ( Fig. 17C ):Apophyses anteriores about 2/3 the length of the apophyses posteriores.Abdominal sternum VIII deeply emarginated at middle. Ostium bursae widely open.Antrum large, membranous, funnel-shaped. Ductus bursae about 1.5 times the length of corpus bursae, narrowed in posterior half. Corpus bursae ovate; signum a large, elongated plate (measuring about 1/3 the length of corpus bursae), with numerous conical spines.

Male unknown.

Distribution. Madagascar (eastern region)

Etymology. The species name is derived from the type locality, Anosibe.
