Diagnosis

This new species is similar to L. tumidosa Park, 2010 in the male genitalia. It can be distinguished by the hindwing with M 3 and CuA 1 stalked, in the male genitalia by the aedeagus with four cornuti, and in the female genitalia by the rounded signum of the corpus bursae; whereas in the latter species, the veins M 3 and CuA 1 are coincident in the hindwing, the aedeagus has more than ten cornuti (Park & Wu 2010: 67, fig. 18), and the signum is triangular (Park & Wu 2010: 69, fig. 25).

Etymology

The specific epithet is derived from the Latin “ duplic -” and “ spineus ”, referring to the two spiniform apical cornuti in the male genitalia.

Description

ADULT (Figs 2C, 6F). Wingspan 16.0‒22.0 mm. Head dark brown, tinged with shining purplish brown, orange yellow laterally. Antenna orange yellow; flagellum ringed with dark brown. Labial palpus with second palpomere orange yellow on inner surface, yellowish brown on outer surface; third palpomere orange yellow dorsally, dark brown ventrally, as long as second palpomere. Thorax and tegula dark brown. Forewing widened distally, costal margin slightly arched, apex rounded, termen oblique; ground colour dark brown; markings blackish brown: basal streak ill-defined; discal stigma small; discocellular stigma larger, elliptical; fringe brown, mixed with yellowish brown, basal line pale orange; R 3 close to R 4+5 at base, R 4 and R 5 long-stalked, M 2 and M 3 subparallel, CuA 1 and CuA 2 short-stalked. Hindwing and fringe pale grey; fringe with pale orange basal line; M 3 and CuA 1 stalked for about ⅓ length of M 3.

MALE GENITALIA (Fig. 11C). Uncus V-shaped; caudal lobe digitiform, rounded apically. Gnathos with lateral arm taenioid and as wide as base of median process; median process elongate, narrowed from base to distal 1/5, then slender, curved ventrad pre-apically almost by right angle. Valva broad basally, narrowed before cucullus; cucullus about half length of valva, subtriangular, narrowed from base to rounded apex, shallowly concave on costal margin, setose on ventral half, with row bullet-shaped setae basally along ventral margin; costal bar narrow basally, widened from middle toward valva, angled at middle; sacculus narrow taenioid, sinuate ventrobasally, reaching cucullus. Vinculum broad; saccus subtriangular with blunt apex. Juxta rectangular, longer than wide, heavily sclerotized on posterior margin, with papillary process at middle on anterior margin; posterior lobe small, triangular, extending dorsad. Aedeagus as long as valva, uniform except widened basally, curved at basal ¼, without dorsal denticle, with dense granules in vesica; cornuti consisting of curved bar about ¼ length of aedeagus, sclerotized plate placed mesially and two large apical spines.

SEVENTH ABDOMINAL STERNITE (Fig. 15I). Anterior margin convex roundly; anterolateral rib broad at base, tapered to apex, not reaching posterior margin of sixth abdominal sternite; posterolateral lobe subrectangular.

FEMALE GENITALIA (Fig. 18E). Eighth abdominal sternite shallowly concave at middle on posterior margin. Apophyses posteriores about twice as long as apophyses anteriores. Antrum rectangular, longer than wide, spiculose. Ductus bursae about 1.5 times as long as corpus bursae, narrowed from posterior 1/5 to middle; ductus seminalis broad, arising from middle of ductus bursae. Corpus bursae ovate; signum situated posterior to middle, small and rounded, densely denticulate.
