Nosphistica abunda Yu et Wang , sp. nov.

( Figs 9 , 22 )

Type material. CHINA, Hainan Province: Holotype ♂ , Wuzhishan , 742 m, 4.VII.2014, leg. Beixin Cong, Linjie Liu & Sha Hu, slide No. YS 17096 . Paratypes (2♂): Guizhou Province: 2♂ , Heiwan , Jiangkou County, 600 m, 27–28.VII.2001, leg. Houhun Li & Xinpu Wang, slide Nos. LSR13148, LSR13157 .

Diagnosis. This species is similar to N. apiculata sp. nov. in both superficial and male genital characters. It differs from the latter in the male genitalia by the uncus obtuse on the posterior margin and the valva widened from distal 1/3 to apex; in N. apiculata sp. nov., the posterior margin of the uncus is triangularly produced and sharply tipped, and the valva is uniform from distal 1/3 to before apex. This species is superficially similar to N. bisinuata Park, 2002 , and the differences between them are stated in the diagnosis of the preceding species.

Description. Adult ( Fig. 9 ) wingspan 12.0–14.0 mm.

Head pale orange, mixed with brown scales. Antenna with scape elongate, pale orange dorsally, brown ventrally; flagellum pale orange, annulated with dark brown dorsally. Labial palpus pale orange, mottled brown scales, becoming denser on outer surface; second segment thickened; third segment slender, nearly as long as second segment.

Thorax and tegula brown. Forewing with costal margin slightly arched, apex obtusely produced, termen concave; ground color dark brown with scattered orange-white scales; discocellular stigma rod-like, gently arched outward, dark brown, surrounded by dense white scales; subterminal line white, running from beyond distal 1/4 of costal margin to dorsum before tornus, arched outward medially; fringe dark brown, mixed with orange white; basal line orange white. Hindwing with costal margin straight, apex sharply produced, termen sinuate twice; ground color brown except dark brown from before middle to distal 1/4 between costal margin and M 3 of wing; dark brown between 3A and dorsum, interrupted by a white patch; discocellular stigma clavate, dilated anteriorly, dark brown, surrounded by dense white scales; subterminal line white, running from distal 1/4 of costal margin to tornus, arched outward at anterior 1/3 and inward at posterior 1/3; fringe dark brown mixed with orange white; basal line orange white. Legs orange white, femora as well as fore and mid tibiae mixed with dense dark brown scales, mid tibia roughly scaled, hind tibia with dense long scales.

Male genitalia ( Fig. 22 ). Uncus sub-pentagonal; posterior margin obtuse, with a setose semicircular process medially; anterior margin shallowly concave medially. Gnathos with basal plate sub-rectangular and bilobate posteriorly; median process broad at base, tapered to apex, curved ventrad at 2/3 almost by a right angle. Valva broad at base, narrowed to 2/3, then slightly widened to obtusely rounded apex; costa broadly and shallowly concave; ventral margin concave from about basal 1/4 to apex; sacculus wide at base, narrowed and terminated beyond middle of ventral margin. Juxta with basal part sclerotized and concave laterally, distal part membranous, triangularly produced anteromedially; lateral process short triangular, with a few setae along inner margin. Vinculum broad, obtuse anteriorly. Aedeagus nearly as long as valva, stout, gently bent; one cornutus relatively large, plate shaped, placed before apex, other cornuti small, thumbtack shaped.

Female unknown.

Distribution. China (Guizhou, Hainan).

Etymology. The specific epithet is derived from the Latin abundus (= abundant), referring to the aedeagus having numerous cornuti in the male genitalia.
