( Figs. 6 View FIGURES 4 − 9 , 15 View FIGURES 14 − 19 , 21 View FIGURES 20 − 26 )

Description. Adult ( Fig. 6 View FIGURES 4 − 9 ). Wing expanse 14.0−16.0 mm. Head snowy white, tinged with pale yellow on neck. Labial palpus snowy white, second segment tinged with pale yellowish brown, third segment with a broad pale yellowish brown ring at distal 1/3. Antenna with scape white, mottled pale golden yellow dorsally; pecten white, length about twice width of scape; flagellum dirty white and yellowish brown. Thorax and tegula snowy white, tegula with pale yellowish brown at base, thorax with two pale golden yellow bands at basal 1/4 and distal 1/3 respectively. Forewing with costal margin gently arched, apex roundly protruding, termen bluntly oblique; ground color pale yellowish brown, covered with scattered ochreous brown scales, area between fold and dorsum paler; Nshaped pinkish white pattern running from basal 2/5 of costal margin obliquely ventrad to distal 1/5 of fold and enlarged triangularly on fold, then obliquely up-outward to distal 1/5 of costal margin and obviously widened on costal margin, finally obliquely arched and becoming thinner to before ventro-apex; first stripe edged with black scales medially and with erect tufts of greyish black scales on its inner margin; second stripe edged with black scales on its outer margin; area between first and second stripes golden yellow along costal margin, tinged with black scales at upper corner, with a rounded dirty white dot above upper corner; third stripe edged with a blackish brown spot on outer margin at apex; fold with scale tufts at basal 1/4, distal 1/3 as well as above its end; fringe yellow to greyish yellow except snowy white tinged with black at posterior corner of termen. Hindwing greyish black; fringe yellowish brown. Legs white tinged with pale yellow scales; tarsi pale yellow.

Male genitalia ( Fig. 15 View FIGURES 14 − 19 ). Uncus broad at base, gradually narrowed to about 2/3, distal 1/3 parallel laterally, apex rounded. Gnathos somewhat beak-like, broad at base, narrowed to hooked apex, toothed distally; lateral arms narrowly band-shaped. Valva short and broad, sub-rectangular, slightly widened from middle to bluntly rounded apex; costa curved at distal 2/5; ventral margin deeply concave beyond end of sacculus. Sacculus narrow, arched ventrally, with a triangular distal process directing downward. Vinculum narrowly banded. Saccus inverted triangular. Juxta sub-trapezoidal, anterior margin slightly concave inward medially, posterior margin shallowly and widely concave; postero-lateral angle almost extending horizontally outward, forming a pair of small triangular lobes. Aedeagus stout, tubular, slightly shorter than valva, distal 1/3 narrowed obliquely to rounded apex; cornuti consisting of three large sclerotized irregular plates, median one bearing at least three teeth.

Female genitalia ( Fig. 21 View FIGURES 20 − 26 ). Papillae anales setose, rounded caudally. Apophyses posteriores about twice length of apophyses anteriores. Eighth sternite with posterior margin straight, with long setae, posterior half parallel laterally, anterior half gradually narrowed, anterior margin rounded. Ostium bursae round, anteriorly closed. Antrum inverted trapezoidal. Ductus bursae narrow basally, widened toward corpus bursae, granulous in inner wall, with large sclerotized plates medially; ductus seminalis arising from between basal 1/3 and 2/3 of ductus bursae. Corpus bursae ovate, longer than ductus bursae; signum triangular, toothed, anterior margin dentate.

Type material. Holotype ♂, Mt. Jiulong (22°23′N, 118°53′E), Zhejiang Province, 530 m, 4 Jul. 2013, genitalia slide No. YAH13032, coll. Aihui Yin and Xiuchun Wang ( NKUM). Paratypes: 2 ♀♀, same data as holotype except dated 3 Jul. 2013 ( NKUM); 1 ♀, same data as holotype except dated 7 Jul. 2013 ( NKUM).

Distribution. China (Zhejiang).

Diagnosis. This new species is similar to L. camaropa by the sacculus having a triangular process in the male genitalia. It can be distinguished by the forewing with ground color pale yellowish brown and the dorsum without ocherous yellow spot near the base; the valva bluntly rounded apically and the distal process of the sacculus shorter than half width of the valva. In L. camaropa , the ground color of the forewing is dark ocherous brown and the forewing has an ocherous yellow spot near the base of the dorsum; the valva is truncate apically and the distal process of the sacculus is longer than half width of the valva in the male genitalia.

Etymology. The epithet of this new species is from the type locality.
