Figs 4D , 8C , 13D , 17E

Diagnosis

The new species is superficially similar to L. anglijuxta Wu, 1997 and L. serratiloba sp. nov. The new species can be distinguished from the species mentioned above in the male genitalia by the cucullus being widened distally and having a ventral spine; in L. anglijuxta and L. serratiloba , the cucullus is narrowed distally and has no ventral spine ( Wu 1997: pl. 11 fig. 1).

Etymology

The specific epithet is derived from the Latin “ parvi -” and “ spineus ”, referring to the small process of the juxta on the posterior margin of the male genitalia.

Description

ADULT ( Figs 4D , 8C ). Wingspan 14.0‒15.0 mm. Head brownish orange except white on frons and vertex. Antenna creamy white. Labial palpus orange pale yellow; third palpomere longer than second palpomere. Thorax and tegula brownish orange. Forewing with costal margin nearly straight, apex triangularly produced, termen gently concave below apex; ground colour brownish orange except ochreous yellow below costal margin from about middle to apex; discal stigma absent; discocellular stigma oblong, dark brown; apex with very small greyish black spot; fringe brown basally, greyish black distally, basal line orange white; R 3, R 4 and R 5 stalked, R 5 to termen, M 2 and M 3 subparallel, CuA 1 and CuA 2 stalked for about 2/5 length of CuA 1. Hindwing grey, with pale yellow scales along veins; fringe brownish orange, basal line orange white; M 3 and CuA 1 stalked for about ⅓ of length of CuA 1.

MALE GENITALIA ( Fig. 13D ). Uncus short, subtriangular. Gnathos with basal plate rectangular, arched on posterior margin; median process broad in basal half, narrowed from middle to distal ⅓, thereafter slender to pointed apex, curved ventrad. Valva broad basally, narrow to cucullus; cucullus about half length of valva, narrowed to basal 2/5, thereafter widened to bluntly rounded apex, densely setose, costal margin shallowly concave, ventral margin with large spine at basal 2/5 and 2‒3 rows of bullet-shaped spines from spine to apex; costal bar narrow, slightly arched; sacculus broad in basal half, narrowed to before cucullus, with cluster of piliform setae medially. Vinculum broad; saccus with blunt anterior margin. Juxta shield-shaped, semicircularly concave medially and with small spiniform process at middle on posterior margin, subquadrately produced at middle on anterior margin; posterior lobe narrow taenioid, extending outward. Aedeagus nearly as long as valva, uniformly wide in basal half, narrowed from middle to apex, curved before middle, with one dorsal denticle; cornuti consisting of large spine at middle and long, narrow sclerite with apical tooth placed in distal ⅓.

SEVENTH ABDOMINAL STERNITE ( Fig. 17E ). Anterolateral rib broad at base, tapered to apex, reaching before middle of sixth abdominal sternite; posterolateral lobe elongate horn-shaped.

Female

Unknown.

Distribution
