( Figs. 4, 5 View FIGURES 4 − 9 , 14 View FIGURES 14 − 19 , 20 View FIGURES 20 − 26 )

Description. Adult ( Figs. 4, 5 View FIGURES 4 − 9 ). Wing expanse 12.0−14.0 mm. Head snowy white, tinged with pale ocherous yellow on neck. Labial palpus snowy white; first segment covered with blackish brown scales dorsally; second segment tinged with pale ocherous brown, denser ventrally; third segment with broad pale ocherous brown band at distal 1/3, acute at apex. Antenna with scape snowy white, covered with pale ocherous brown scales on dorsal surface; pecten whitish yellow, with length about 1.5 times width of scape; flagellum pale ocherous yellow, ringed with white. Thorax and tegula white; thorax horizontally with a band of golden yellow scales near base and near posterior margin respectively, golden yellow apically; tegula tinged with golden yellow basally and distally. Forewing with costal margin gently arched, apex triangular, termen bluntly oblique; ground color pale yellowish brown, paler between fold and dorsum; N-shaped pinkish white pattern running from basal 2/5 of costal margin obliquely outward down to lower angle of cell, then arched obliquely up-outward to end of costal margin, and enlarged triangularly on costal margin, finally obliquely outward and narrowed down to ventro-apex; first stripe edged with black scales and erect greyish brown scale tufts on inner margin, upper corner between first and second stripes with an ill-defined strip, above it set a dirty white dot, second and third stripes both edged with black scales on outer margin; fold with scale tufts near base, at 2/3 and above end; fringe with basal 3/5 golden yellow, distal 2/ 5 greyish white tinged with blackish brown and pink. Hindwing deep grey; fringe greyish yellow. Legs with white basal segment, femur and tibia; tibia tinged with pale ocherous brown; tarsus ocherous brown except snowy white at apex of each segment.

Male genitalia ( Fig. 14 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 from lateral view, triangular from frontal view, broad at base, narrowed to hooked apex, with granules; lateral arms band-shaped. Valva short and broad, sub-rectangular, apex blunt, more or less sinuate; costa concave at base, gently concave distally; ventral margin triangularly concave beyond end of sacculus, then arched to apex. Sacculus narrow, slightly arched ventrally; distal process triangular, directing downward, about 1/3 width of valva. Vinculum narrowly banded. Saccus inverted trapezoidal, straight on posterior margin, blunt on anterior margin. Juxta H-shaped; anterior margin concave at middle semicircularly; posterior margin widely concave, extending obliquely outward postero-laterally, forming a pair of triangular lobes. Aedeagus stout, tubular, slightly shorter than valva, distal 1/3 narrowed obliquely to rounded apex; cornuti consisting of about six small sclerotized irregular plates.

Female genitalia ( Fig. 20 View FIGURES 20 − 26 ). Papillae anales setose, rounded caudally. Apophyses posteriores about twice length of apophyses anteriores. Eighth sternite with posterior margin straight, setose, posterior half parallel laterally, anterior half slightly narrowed, anterior margin blunt. Ostium bursae small, triangular, open anteriorly. Antrum rectangular, slightly longer than width. Ductus bursae narrow basally, widened distally, with small sclerotized plates or ridges, granulous in inner wall; ductus seminalis arising from between basal 1/4 and 3/4 of ductus bursae. Corpus bursae elongate ovate, densely granulous; signum triangular, concave and dentate on anterior margin.

Type material. Holotype ♂, Mt. Jianfeng (18°45′N, 108°51′E), Hainan Province, 1050 m, 29 Apr. 2013, genitalia slide No. YAH13037, coll. Yinghui Sun et al. ( NKUM). Paratypes: 2 ♀♀, same locality as holotype, 940 m, 4 Jun. 2007, coll. Zhiwei Zhang and Weichun Li ( NKUM); 1♀, same locality as holotype, 940 m, 6 Jun. 2007, coll. Zhiwei Zhang and Weichun Li ( NKUM); 1 ♂, Tam Dao Nat. Park, Vietnam, 950 m, 24 May 2007, coll. K. T. Park ( KNA).

Distribution. China (Hainan), Vietnam (North).

Diagnosis. This new species is similar to L. camaropa in the male genitalia with the sacculus having a triangular down-oriented distal process, but can be separated from the latter by the forewing with pale yellowish brown ground color lacking an ocherous yellow spot near the base of dorsum. It is also similar to L. jiulongshana sp. nov., but can be distinguished by the cornuti consisting of six small plates in the male genitalia and the ostium bursae open anteriorly in the female genitalia; whereas in L. jiulongshana sp. nov., the cornuti consist of three large plates and the ostium bursae is closed anteriorly.

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

Note. The valva of the male genitalia is roundly protruded ventro-apically in the specimen collected from Vietnam.
