( Figs. 11 View FIGURES 10 − 13 , 25 View FIGURES 20 − 26 )

Description. Adult ( Fig. 11 View FIGURES 10 − 13 ). Wing expanse 16.0 mm. Head with frons yellowish brown, vertex silvery white. Labial palpus pale yellowish brown, outer surface of first and second segments whitish yellow except second segment yellowish brown distally, third segment with a broad deep yellowish brown ring at distal 2/5. Antenna pale yellow on ventral surface; scape brown on dorsal surface, pecten greyish yellow, length about twice width of scape; flagellum with greyish brown rings on dorsal surface. Thorax yellowish brown, with whitish yellow transversal bands at basal 1/3 and 2/3, distal 1/3 tinged with white; tegula yellowish brown, with a transversal whitish yellow band at middle. Forewing with costal margin gently arched, apex rounded, termen bluntly oblique; ground color dominantly dark ocherous brown, pale yellowish brown between area of fold and dorsum, apex yellow; N-shaped pattern dirty white, tinged with pale rosy scales, running ventrad and curved from beyond basal 1/3 of costal margin to lower angle of cell, enlarged, then sinuate up-outward to distal 1/4 of costal margin, enlarged to a triangular, somewhat rosy spot at costal margin, finally from costal 1/4 straightly to ventro-apex, becoming thinner; first stripe edged with black scales on outer margin, large black diffusion placed between corner of first and second stripes, second and third stripes edged with black scales on outer margin, third stripe pale rosy; distinct erect scale tufts at middle of cell and slightly beyond middle of fold respectively, other scales tufts indistinct due to abrasion; fringe along apex yellowish brown basally, white medially, greyish black distally, pale rosy tinged with greyish black scales along termen. Hindwing greyish black; fringe pale greyish black. Legs white; tibia tinged with pale yellow brown patches; tarsus with white rings.

Female genitalia ( Fig. 25 View FIGURES 20 − 26 ). Papillae anales setose on ventral surface. Apophyses posteriores about 1.5 times length of apophyses anteriores, both apophyses truncate terminally. Eighth sternite with posterior half parallel laterally, anterior half gradually narrowed, posterior margin straight, anterior margin rounded. Ostium bursae rounded, open anteriorly. Antrum somewhat square, heavily sclerotized. Ductus bursae with basal 1/4 narrow, inner wall smooth; distal 3/4 widened toward corpus bursae, inner wall with dense particles; large sclerotized plates placed medially; ductus seminalis from between basal 1/3 and distal 1/5 of ductus bursae. Corpus bursae ovate, not distinctly separated from ductus bursae, inner wall granulous; signum folding to a triangular plate, toothed, anterior margin dentate, slightly arched inward.

Male unknown.

Type material. Holotype ♀, Mt. Simian (28°36′N, 106°24′E), Chongqing, 1200 m, 17 Jul. 2012, coll. Yinghui Sun and Aihui Yin, genitalia slide No. YAH13039 ( NKUM).

Distribution. China (Chongqing).

Diagnosis. This new species is similar to L. camaropa . It can be distinguished from the latter by the yellowish brown thorax with whitish yellow transversal bands at basal 1/3 and 2/3, the forewing with apex golden yellow and lacking the ocherous yellow spot near the base of dorsum. In L. camaropa , the thorax is entirely dark ocherous brown, the forewing is blackish brown at apex and has a bright ocherous spot near the base of dorsum.

Etymology. The epithet of this new species is from Latin flava-, meaning yellow, and terminatus, meaning terminal, referring to the yellow apex in the forewing.

Material examined. 1♂, Mt. Qingcheng, Sichuan Province, 14 Aug. 1990, other data unknown ( NKUM); 1♂, Dahonghai, Chongqing, 1200 m, 13 Aug. 2012, coll. Xiaofei Yang and Tengteng Liu ( NKUM). Diagnosis. This species is characterized by the forewing with a bright ocherous yellow spot near the base of dorsum ( Fig. 12 View FIGURES 10 − 13 ), and the valva truncate at the apex in the male genitalia ( Fig. 18 View FIGURES 14 − 19 ).

Distribution. China (Sichuan).

Qiang Gao and Na Chen; 1♀, Xiachuanbaohuzhan, 1600 m, 19 Jul. 2012, coll. Qiang Gao and Na Chen. (All deposited in NKUM).

Diagnosis. This species can be distinguished from its congeners by the sacculus without a distal process ( Fig. 19 View FIGURES 14 − 19 ). It is more similar to L. pallidiptera sp. nov. superficially ( Fig. 13 View FIGURES 10 − 13 ), but can be separated by the ovate ostium bursae open anteriorly ( Fig. 26 View FIGURES 20 − 26 ), whereas it is closed in the latter species.

Distribution. China (Guangdong, Guizhou, Henan, Shaanxi, Yunnan).
