(Figs. 10, 24)
Description. Adult (Fig. 10). Wing expanse 16.0 mm. Head yellowish brown, creamy white near base of antenna. 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 deep yellowish brown except yellowish brown distally; tegula yellowish brown, darker basally. Forewing with costal margin nearly straight, apex triangularly protruded, termen bluntly oblique; ground color dark ocherous brown, tinged with sparse black scales, with erect tufts: conspicuous small scale tufts slightly beyond basal 1/3 below costal margin and at about middle of cell respectively, large scale tufts at distal 1/4 of fold and near lower angle of cell; N-shaped pattern pale rosy, running from beyond basal 1/3 of costal margin obliquely straight ventrad to lower angle of cell, then sinuate up-outward to costal 3/4, forming a pinkish triangular spot at costal 3/4, finally becoming thinner and curved to before ventroapex; black spot situated above lower angle of cell, just between corner of first and second stripes, second stripe edged with black scales medially on outside, third stripe edged with blackish brown at ventro-apex; fringe yellow to greyish yellow, distally grey around apex. Hindwing blackish brown; fringe greyish brown. Legs yellowish white; tibia with yellowish brown patches; tarsus with white rings.
Female genitalia (Fig. 24). Papillae anales setose ventrally, caudal margin rounded, with a small concavity at middle. Apophyses posteriores about twice length of apophyses anteriores. Eighth sternite with posterior half rectangular, parallel laterally, posterior margin straight, with long setae; anterior half trapezoidal, gradually narrowed, anterior margin blunt. Ostium bursae small, rounded, closed anteriorly. Antrum short, rectangular, wider than long. Ductus bursae narrowed basally, with smooth inner wall, widened toward corpus bursae distally, weakly sclerotized, with granulous inner wall, with weakly sclerotized plates; ductus seminalis from distal half of ductus bursae. Corpus bursae elongate, pear-like, densely granulous; signum folding to a triangular plate, toothed densely, anterior margin dentate, slightly concave medially.
Male unknown.
Type material. Holotype ♀, NP. Bavi (top), Hanoi Province, Vietnam, 19 Jul.-5 Aug. 2010, genitalia slide No. YAH13042, coll. Bae and Vi (INU).
Distribution. Vietnam (North).
Diagnosis. This new species is similar to L. camaropa in forewing color. It can be distinguished from the latter by the forewing with the second and the third stripes of the N-shaped pattern triangularly enlarged at costal margin, which is narrowly arched in L. camaropa; the forewing lacks the ocherous yellow spot near base of the dorsum, which is present in L. camaropa.
Etymology. The epithet of this new species is derived from Latin rosa-, meaning rose, and taenius, meaning band, referring to the N-shaped pattern in the forewing.
