( Figs. 7 View FIGURES 4 − 9 , 16 View FIGURES 14 − 19 , 22 View FIGURES 20 − 26 )
Description. Adult ( Fig. 7 View FIGURES 4 − 9 ). Wing expanse 16.0−18.0 mm. Head snowy white, tinged with pale yellow on vertex. Labial palpus snowy white, second segment tinged with pale yellow, third segment with a broad pale yellowish brown ring at distal 1/3. Antenna snowy white; scape tinged with pale yellow dorsally, pecten length about 1.2 times width of scape; flagellum yellowish brown on ventral surface. Thorax and tegula snowy white, thorax with two pale yellow bands at basal 1/4 and distal 1/3 respectively. Forewing with costal margin almost straight, apex roundly protruding, termen obliquely blunt; ground color pale yellowish brown, tinged with pale ocherous yellow, area between fold and dorsum snowy white mottled pale ocherous; large N-shaped creamy pattern running from basal 2/5 of costal margin obliquely ventrad to above distal 1/3 of fold, then arched obliquely up-outward to end of costal margin and largely expanded on costal margin, finally obliquely arched outward and then straight downward to before ventro-apex; first stripe edged with an ill-defined broad ocherous brown band bearing distinct erect scale tufts on its outer margin; areas between first and second stripes ocherous brown, between upper corner of two stripes set a crescent blackish brown strip, with a white circle above its middle, between lower corner of second and third stripes placed a dark ocherous brown patch, third stripe tinged with pink scales, edged with ocherous brown on outer margin; ventro-apex with a blackish brown spot; distinct scale tufts above fold near base, at 3/5 of fold and at distal 1/5 above fold; fringe golden yellow basally, white medially, greyish brown distally. Hindwing dark brown; fringe deep greyish yellow. Legs white tinged with pale yellow scales; tarsi ventro-distally yellowish brown, with short spines.
Male genitalia ( Fig. 16 View FIGURES 14 − 19 ). Uncus broad at base, gradually narrowed to about 3/5, distal 2/5 slightly narrowed to blunt apex. Gnathos somewhat beak-like, toothed, broad at base, narrowed to hooked apex; lateral arms narrowly banded. Valva short and broad, sub-rectangular, slightly widened from distal 2/5 to bluntly rounded apex, setose distally; costa curved at distal 2/5; ventral margin semicircularly concave inward beyond end of sacculus, triangularly protruding distally. Sacculus narrow, slightly arched ventrally, distally with a triangular process directing downward. Vinculum narrowly banded. Saccus somewhat inverted trapezoidal, blunt anteriorly, arched posteriorly. Juxta sub-trapezoidal, anterior margin slightly concave inward medially, posterior margin concave widely, forming a pair of digitate lateral lobes, lateral margin with a small tooth at middle. Aedeagus stout, tubular, slightly shorter than valva, distal 1/3 narrowed obliquely to rounded apex; cornuti consisting of three to four large sclerotized, irregular plates.
Female genitalia ( Fig. 22 View FIGURES 20 − 26 ). Papillae anales setose, rounded posteriorly. Apophyses posteriores about twice length of apophyses anteriores. Eighth sternite with long setae on posterior margin, posterior half parallel laterally, anterior half gradually narrowed to rounded anterior margin. Ostium bursae round, closed anteriorly. Antrum inverted trapezoidal. Ductus bursae narrow basally, widened toward corpus bursae, granulous in inner wall, with large sclerotized plates medially; ductus seminalis arising from anterior to antrum. Corpus bursae ovate; signum triangular, toothed, anterior margin arched and dentate.
Type material. Holotype ♂, Mt. Godae-san, Yeoncheon-gun, Gyeongbuk Province, Korea, 11−12 Jul. 2000, genitalia slide No. YAH13043, coll. Peak, Kim, Kim & Ko. Paratypes: 1 ♀, Mt. Duta-san, Samcheok, Gangwon Province, 20 Apr. 2002, coll. Huilin Han; 1 ♂, Jiamri, Chuncheon, Gangwon Province, Korea, 24 Jul. 1995, coll. Y. M. Park; 1 ♂, Mt. Jeombong-san, Gangwon Province Korea, 22. Vi. 1992, coll. KT Park. All types are deposited in KNA.
Distribution. Korea (Central).
Diagnosis. This new species is similar to L. xanthacma superficially, but can be distinguished by the sacculus with a downward-directed distal process in the male genitalia and the ostium bursae is closed anteriorly in the female genitalia; in L. xanthacma the sacculus does not have a distal process, and the ostium bursae is open anteriorly. The species is also similar to L. jiulongshana sp. nov., but can be separated from the latter by the forewing with the corner of the stripe between the first and the second stripes gently arched, the juxta with fingerlike postero-lateral lobes in the male genitalia, and the corpus bursae with a larger signum in the female genitalia; in L. jiulongshana sp. nov., the stripe at the corner between the first and second stripes is triangular on the forewing, the postero-lateral lobes of juxta are short triangular, and the signum is relatively smaller.
Etymology. The epithet of this new species is derived from Latin pallidius, meaning pale, and – pterus, meaning wing, referring to the pale ground color of the forewing.
