description: Dusungwua paripalpa Ren & Li, sp. nov.
(Figs 1, 10, 21)
Type material. Holotype. [CHINA] ♂, Zhangjiajie (29°07΄N 110°29΄E), Hunan, 650 m, 11-VIII-2001, coll. Shulian Hao, gen. slide No. RYD04803. Paratype. [CHINA] 1 ♂, same data as for holotype.
Diagnosis. This new species is similar to D. ohkunii. It can be distinguished by the second and third segments of the labial palpus about equal length; the forewing with a few scattered grayish white scales not forming a pattern; the gnathos constricted near middle, slightly expanded in distal half, and the lobate juxta with the lateral lobe slightly incurved distally in the male genitalia. In D. ohkunii, the second segment of the labial palpus is 1.5 times length of third segment; the forewing is covered with numerous grayish white scales that form a wedge-shaped grayish white blotch between the antemedial and the postmedial lines; the clubbed gnathos is slightly broader at middle, and the hillock-shaped lateral lobe of the juxta is not incurved distally in the male genitalia.
Description. Adult (Fig. 10) with wingspan 16.0̅18.0 mm. Head grayish brown. Antenna brown, scape about 1.5 times as long as wide; male flagellum simple, neither constricted nor incurved basally. Labial palpus upturned beyond vertex; first segment grayish white; second and third segments brown, about equal length. Maxillary palpus grayish brown. Patagium, tegula and thorax blackish brown. Forewing fuscous brown, with scattered grayish white scales; antemedial line grayish white, from costal 2/5 obliquely outward to dorsal 3/7, its inner margin bordered with an indistinct, ovate, blackish brown patch near dorsum; discal spots blackish brown, fused, crescent; postmedial line grayish white, indistinct, incurved at M 1 and CuA 2; terminal line brown; cilia grayish brown to blackish brown. Hindwing and cilia grayish brown. Fore leg grayish brown, midleg and hindleg grayish white; tarsi fuscous brown, white at apex of each tarsomere. Abdomen with dorsal surface brown, darker in basal half of each segment, ventral surface yellowish brown.
Male genitalia (Fig. 21). Uncus triangular, about same length as width at proximal base, gradually narrowed to rounded apex. Gnathos about 4/7 length of uncus, constricted near middle, slightly expanded from middle to before apex; apex attenuated, bifid. Transtilla produced in U shape posteriorly; postero-lateral lobe three times as long as wide, fingerlike, uniform in width, rounded at apex. Valva narrow, four times as long as wide, almost parallel-sided; clasper an indistinct mastoid process at middle near base; costa extending to near end of valva; sacculus 2/5 length of valva, slightly sinuate, narrowed from somewhat broad base to pointed apex. Juxta semicircular; lateral lobe slightly shorter than gnathos, slightly incurved distally, truncate apically, bearing long setae. Vinculum U-shaped, same length as maximum width, almost straight on anterior margin. Phallus cylindrical, slightly curved, about 4/5 length of valva, with sclerotized crimples in distal 2/3.
Female. Unknown.
Distribution. China (Hunan).
Etymology. The specific name is derived from the Latin prefix pari -, meaning parity, and the morphological term palpus, referring to the second and third segments of the labial palpus about equal length.
