Rhopobota zhengi View in CoL sp. nov.

( Figs. 4 View FIGURES 1 – 5 , 9 View FIGURES 6 – 10 , 12 View FIGURES 11 – 13 )

Diagnosis. This species is similar to R. okui Nasu, 2000 , but it can be distinguished from the latter by the dark brown spot on end of cell of the forewing and the hooked arms of uncus in the male genitalia. In R. okui the forewing lacks the dark brown spot on end of cell and the arms of uncus are boot-shaped. Rhopobota zhengi is also similar to R. hamata in the male genitalia, but it can be separated from the latter by the dark brown spot at the end of cell in the forewing and by the two thick flagellate setae (lost) of the cucullus. In R. hamata sp. nov., the forewing has an elongate triangular brown patch narrowing posteriorly on termen, and the cucullus has seven thick flagellate setae.

Description. Adult ( Fig. 4 View FIGURES 1 – 5 ). Head: Vertex with brown scales; frons white. Antenna brown except white scape. Labial palpus with basal two segments brown, third segment small, white and porrect. Thorax: Dorsum and tegula grayish brown. Forewing length 6.0 mm; upperside ground color gray; apex slightly protruding; basal patch and median fascia indistinct; with a dark brown spot situated at end of cell; speculum nearly quadrate, white, containing some brown dots; costa with nine pairs of blurry white strigulae from base to apex: strigulae 1-4 between base and intersection of Sc with costa; strigulae 5 and 6 between Sc and R1; distal three pairs more well defined than other strigulae, distributed between pairs of veins R1-R2, R2-R3, R3-R4; cilia gray, with brown basal line. Hindwing and cilia gray. Foreleg brown; midleg grayish brown, tarsus with brown scales; hindleg gray, tarsus brown. Abdomen: Male genitalia ( Fig. 9 View FIGURES 6 – 10 ) with uncus bearing long bifid arms, curved before middle, hook-shaped; socius large, digitate, hairy. Valva long, straight ventrally; neck undefined; costa protruding markedly near base; sacculus with a relatively small process on ventral edge of basal opening, and a long horn on posterior edge reaching costa; cucullus hairy, with two thick flagellate setae (lost) situated near ventral angle and six thick hairs dorsally. Phallus broad and short, tubular; cornuti numerous, spiculate. Female genitalia ( Fig. 12 View FIGURES 11 – 13 ) with papilla analis elongate triangular, hairy; posterior apophysis slightly longer than anterior apophysis. Ostium subtriangular; sterigma produced into an inverted V-shaped slender sclerite. Ductus bursae broad, short, sclerotized, except membranous at base and near junction with corpus bursae. Corpus bursae pyriform, with a large, inverted V-shaped sclerite extending from entrance of corpus bursae to posterior 2/5 along sides; two spine-like signa with rounded bases.

Holotype. Male, CHINA: Fujian Province: Mt. Wuyi (26.54˚N, 116.42˚E), 1000 m, 26.v. 2004 (Haili Yu), genitalia slide no. ZAH04205.

Paratypes. 2 males, 2 females, same data as holotype.

Etymology. The species is named in honor of Professor Zhemin Zheng (Xi'an, China) for his outstanding contributions to systematic entomology.
