Torodora gongshanensis Yu et Wang , sp. nov.

( Figs 7 , 25 , 42 )

Type material. CHINA, Yunnan: Holotype ♂ , Pukawang Village (27°50′N, 112°19′E), Gongshan County, 1335 m, 9. VI.2017, leg. KJ Teng et al., slide No. YS 20066 . Paratypes (4♂ 1♀): 2♂ 1♀, same data as holotype except dated 10, 12. VI.2017, slide Nos. YS 20174 ♂, YS20175 ♀; 1♂, Qinlangdang , Gongshan County, 380 m, 28. V.2017, leg. KJ Teng et al .; 1♂, Xiajinchang , Malipo County, 1470 m, 29.VII.2016, leg. KJ Teng, GE Lee & T Wang .

Diagnosis. This new species is similar to T. moriyasu Park, 2002 in both appearance and male genitalia. It can be distinguished by the labial palpus with rough scales dorsally, in the male genitalia by the juxta with a large horn at middle on the posterior margin and with a pair of serrate posterolateral lobes; in T. moriyasu , the labial palpus is smooth, the juxta lacks a horn at middle on the posterior margin and its posterolateral lobes are smooth ( Park 2002: 163, fig. 34).

Description. Adult ( Fig. 7 ). Wingspan 11.0‒12.0 mm.

Head brown. Antenna with scape brown, flagellum pale yellow. Labial palpus brown, with dense rough scales dorsally, third palpomere slightly shorter than second palpomere.

Thorax and tegula brown. Forewing with costal margin slightly arched, apex triangularly produced, termen shallowly concave; ground color dark brown, mixed with orange white scales, orange yellow from basal 1/3 to before apex along costal margin; discal and discocellular stigmata blackish brown, subrounded, subequally sized; fringe greyish black, basal line greyish white. Hindwing and fringe pale greyish brown; fringe with an orange white basal line. Legs pale yellow except all femora and mid tibia brown ventrally.

Male genitalia ( Fig. 25 ). Uncus wide at base, distinctly narrowed to beyond middle, thereafter slightly narrowed to subacute apex. Gnathos with basal plate triangularly produced posteriorly; mesial process wide at base, narrowed to basal 3/5, thereafter abruptly narrowed to pointed apex, curved ventrad at distal 2/5 by a right angle. Valva wide at base, slightly narrowed to cucullus; cucullus about 3/5 length of valva, subparallel-sided to an obliquely obtuse apex, arched ventrally; costa obtusely arched at proximal base, shallowly concave medially; sacculus wide at base, narrowed to before cucullus, obliquely straight ventrally. Vinculum obtuse on anterior margin. Juxta widened posteriorly, triangularly produced anteriorly, with a large horn at middle on posterior margin slightly longer than half length of juxta; posterolateral lobe rod-shaped, serrate, about 1/3 length of juxta. Aedeagus slightly shorter than valva, slightly tapered from base to obtuse apex; cornuti consisting of rows of thumbtack-shaped and conic spines running from about basal 1/3 to 2/3, and a horn with a weakly sclerotized basal plate near apex.

Female genitalia ( Fig. 42 ). Eighth abdominal sternite notched at middle on posterior margin, forming two semiovate lateral lobes. Apophyses posteriores about 1.5 times length of apophyses anteriores. Antrum heavily sclerotized, subquadrate. Ductus bursae shorter than corpus bursae, wrinkled, with 10 thumbtack-shaped spines; ductus seminalis narrower, arising from ductus bursae posteriorly, dilated subbasally. Corpus bursae large, elliptical; signum situated posterior to middle, subrectangular, about 3/5 width of corpus bursae, denticulate, heavily sclerotized along posterior margin.

Distribution. China (Yunnan).

Etymology. The specific epithet is derived from the type locality.
