Park, Kyu-Tek & Bae, Yang-Seop, 2020, Genus Torodora Meyrick (Lepidoptera, Lecithoceridae, Torodorinae) in Laos with descriptions of five new species and two newly recorded species, Zootaxa 4851 (2), pp. 305-318 : 316

Torodora metasaris ( Meyrick, 1911) , comb. nov.

( Figs. 7 A-F)

Brachmia metasaris Meyrick, 1911: 712 . TL: N India, Khasis. [NHMUK]

Lecithocera metasaris ; Meyrick, 1925: 238; Clarke, 1965: 144; Pathania et al., 2015: 6.

Diagnosis. Wingspan 11.0 mm. This species is superficially similar to T. flavescens Gozmány , but it can be distinguished from the latter by its hind tibia with expansible brush of very long, whitish hairs above. The male genitalia are also very similar to those of T. flavescens , but can be distinguished by the uncus with sharply pointed lateral apices; juxta flat on caudal margin, with median vertical ridge and latero-caudal lobes directed outward, sharply pointed, with a short, quadrate protrusion on anterior margin medially; aedeagus lacking long needle-like cornuti. However, in T. flavescens , the uncus has rounded apices, the juxta has no median ridge and no such protrusion on anterior margin, and the aedeagus has a pair of different length of needle-like cornuti. Description of the venation ( Fig. 7D ): R 1 arising from beyond middle; distance between origins of R 2 and R 3 less than 1/3 length of R 1 and R 2; R 3 stalked with R 4+5 for more than 1/2 length; R 4 and R 5 stalked beyond 3/5; R 5 close apex; M 1 close to R3+4; M 2 much nearer to M 3; CuA 1 and CuA 2 short-stalked; hind wing with M 2 well-developed; M 3 and CuA 1 stalked for basal 1/3.

Male genitalia ( Figs. 7 E–H): Uncus broadened distally, concave on caudal margin. Median process of gnathos broad, narrower toward apex, strongly bent beyond 2/3 downward. Tegumen weakly sclerotized, deeply concave on anterior margin. Valva broad at base, basal part nearly quadrate, deeply concave on costa; sacculus broadly developed, extended to lower corner of cucullus; cucullus thumb-shaped with rounded outer margin, dense setose. Juxta broad, rectangular, with latero-caudal process directed outward, sharply produced apically; short, quadrate protrusion on anterior margin medially; with well-developed central ridge vertically. Vinculum banded. Aedeagus stout, shorter than valva, narrowed in distal half, slightly bent into S-shape; cornuti consisting of two rows of thread-like scales.

Female unknown.

Material examined. LAOS: 1♂, Bolikhamsai Prov., Tad Leuh Waterfall , 1 viii 2019, 18°23’42’’N 103°04’ 04’’E, leg. YS Bae, MJ Qi, DJ Lee, TG Lee, YB Cha, JH Ko, & CM Jang, gen. side no. CIS-8075. Paratype: 1♂, same locality as holotype, 3 viii 2009, same collectors, gen. slide no. CIS-8074 .

Distribution. Laos (new record: Bolikhamsai), India (North).

Remarks. The specimens from Laos are smaller than the type, with wingspan 11 mm (via. 17 mm in the type), but the male genitalia are well accordant with those of the type and identified it as conspecific here. A further study is needed for re-confirmation.
