Diagnosis

The new species is similar to L. haviensis Park, 2016 in both appearance and male genitalia. The new species can be distinguished in the male genitalia by the cucullus being narrowed from the middle to the apex, the saccus triangular, and the aedeagus without V-shaped cornutus; in L. haviensis , the cucullus is narrowed from basal 2/5 to apex, the saccus is almost semiovate, and the aedeagus has a V-shaped cornutus.

Etymology

The specific epithet is derived from the Latin “ parv -” [= small] and “ flavus ” [= yellow], referring to the small size and the colour of the forewing.

Description

ADULT ( Fig. 4C ). Wingspan 10.0 mm. Antenna pale yellow, ringed with dark brown distally. Labial palpus with second palpomere pale yellow on inner surface, brownish yellow on outer surface; third palpomere pale yellow dorsally, dark brown ventrally, slightly shorter than second palpomere. Thorax and tegula pale yellow. Forewing with costal margin slightly arched, apex blunt, termen oblique; ground colour pale yellow, with scattered brown scales; markings blackish brown: basal streak narrow, about 1/5 length of costal margin; discal stigma rounded; discocellular stigma larger, elliptical; fringe orange white; R 3, R 4 and R 5 stalked, R 5 to termen, M 2 and M 3 separated, CuA 1 and CuA 2 short-stalked. Hindwing and fringe pale greyish brown; M 3 and CuA 1 long-stalked.

MALE GENITALIA ( Fig. 13C ). Uncus nearly trapezoidal, concave in broad V-shape on posterior margin; caudal lobe subovate. Gnathos with lateral arm broad, triangular and bearing two denticles on posterior margin; median process wide at base, narrowed to basal 3/5, distal 2/5 arched and slender to pointed apex. Valva broad basally, narrowed to cucullus; cucullus about half length of valva, tubular in basal half, narrowed to rounded apex, shallowly concave on costal margin, sparsely setose, with several bullet-shaped setae medially along ventral margin; costal bar narrow, arched; sacculus taenioid. Vinculum broad; saccus triangular with a blunt apex. Juxta shield-shaped, semicircularly concave on posterior margin, semiovally produced medially on anterior margin; posterior lobe triangular, blunt at apex, extending dorsad. Aedeagus as long as valva, nearly tubular except slightly widened at base, gently curved, with two dorsal denticles, with dense granules in vesica; cornuti consisting of a cluster of strong spines at basal 2/5, long bar about ⅓ length of aedeagus placed medially and plate with apical horn placed distally.

SEVENTH ABDOMINAL STERNITE ( Fig. 17D ). Anterior margin roundly convex; anterolateral rib thin, forked in basal half, reaching posterior margin of sixth abdominal sternite; posterolateral lobe weakly sclerotized, triangular.

Female

Unknown.

Distribution
