Type materials.

Holotype: China • ♂; Xizang Autonomous Region [Tibet], Motuo County [Mêdog], Beibengxiang ; 29.242 ° N, 95.171 ° E; 1239 m elev.; 14 Jun. 2023; Shuai Yu leg.; slide no. LCU 034 , in LCU . Paratypes: 3 ♂ 1 ♀; same data as holotype; slide nos. LCU 033 ♂, LCU 204 ♂, LCU 219 ♀, in LCU .

Diagnosis.

Torodora mici is similar to T. reniformis Yu & Wang, 2022 in the male genitalia. It can be distinguished by the blackish brown forewing, the juxta reaching near posterior margin of the tegumen, and the cornutus an elongate bar; Torodora reniformis has a forewing that is dark brown on the basal 3 / 4 and orange white on the distal 1 / 4 ( Yu et al. 2022: 16), the juxta reaches far from the posterior margin of the tegumen, and the cornuti consists of needle-like spines ( Yu et al. 2022: 24).

Description.

Wingspan 13.5–14.0 mm (Fig. 1 C ). Head dark brown, orange-yellow along lateral surfaces. Antennae yellow. Labial palpus dark brown, distally yellow on second palpomere; third paplomere slender, as long as the second. Thorax and tegula dark brown. Forewing with costal margin nearly straight, slightly curved distally, apex slightly down-curved, termen slightly concave; ground color dark brown, mixed with scattered yellow scales, distal 1 / 4 of the costal margin yellow; discal stigma rounded, black, outer margin edged with yellow scales; plical stigma nearly rounded, black, anteriorly extending toward discal stigma, outer margin edged with yellow scales; discocellular stigma small, paired, located one above another, with a yellow outer margin; subterminal line yellow, extending from 1 / 4 of the costal margin sinuated to the distal 1 / 5 of the dorsum; fringe dark brown, with a yellow basal line; venation with R 1, R 2 free, R 3, R 4, and R 5 stalked, R 5 extending to apex, M 1, M 2, M 3 free, CuA 1 and CuA 2 stalked distally. Hindwing greyish brown; fringe greyish brown, with a yellow basal line; venation with M 2 free, M 3 and CuA 1 stalked basally, CuA 2 distant from M 3 + CuA 1 at the base (Fig. 1 D ).

Male genitalia (Fig. 2 B ). Uncus elongated with widened base. Gnathos with basal plate rounded on posterior margin, median process absent. Valva wide at the base, gradually narrowing to cucullus; cucullus extending obliquely dorsad, apical margin broadly rounded, costal margin nearly straight throughout length, abruptly curved upwards forming inner margin of cucullus; sacculus wide, elongate, densely spiculose. Vinculum U shaped, nearly straight on anterior margin. Juxta rectangular, longer than wide, with a longitudinal median line; posterolateral lobes digitate, reaching near the posterior margin of the tegumen, apex narrowly rounded, setose. Phallus shorter than the valva, straight, uniformly wide basally, narrowing apically; vesica densely granulate; cornutus an elongate bar near apex of vesica.

Female genitalia (Fig. 2 D ). Eighth abdominal sternite medially concave on posterior margin, forming two lateral parts broadly rounded posteriorly. Apophyses posteriores longer than apophyses anteriores. Antrum cup-shaped and membranous. Ductus bursae nearly wide throughout length, bearing sparse spines; ductus seminalis slender, arising from approximately the posterior 1 / 4 of ductus bursae, with dense spinules on the inner wall. Corpus bursae elliptical; signum on posterior end, a transverse plate, bearing dense spinules.

Distribution.

China (Xizang Autonomous Region [Tibet]).

Etymology.

The specific epithet is derived from the Mandarin mi (dense) and ci (spine), referring to the densely spined sacculus of the male genitalia.
