Scaeosopha tuberculata Li et Zhang sp. nov.

( Figs. 16, 40)

Description. Adult ( Fig. 16): Wingspan 17.5 mm. Head yellow, frons and vertex whitish-yellow. Antenna deepyellow, scape mottled black scales on dorsal surface. Labial palpus deep-yellow, second segment with basal half black, third segment with black scales laterally. Thorax grayish-yellow except deep-yellow along margins. Tegula grayish-yellow except basal 1/3 black. Forewing yellow, with dark spots and patches throughout; costal margin with four black spots from base to apex, the third one smallest; two closely spaced black patches at basal 1/3 of cell crossing fold, discontinuous; smaller black dots at base below fold and at 2/3 length of cell respectively; large black patch at end of cell diffused outward then downward to posterior corner of termen, another incompact small patch set near its inside; fold with spot at distal 1/3 and end, the latter diffuse; large elongate patch at half length above dorsum; cilia grayish-yellow mottled deep-gray. Hindwing and cilia dark yellowish-brown. Fore leg with femur deep-yellow, tibia and tarsus black; mid and hind legs yellow, hind tibia with dense short and long bristles on dorsal surface.

Male genitalia ( Fig. 40): Brachia of uncus expanded in basal half, forming a sclerotized quadrate plate; distal half slender, slightly hooked apically. Tegumen nearly equal to brachia of uncus in length. Valva broad and short, evenly convex distally, costa projecting medially in semicircle; valvella longer than length of valva, its distal 1/7 expanded to a densely setose tuberculum. Anellus strongly sclerotized, cone-shaped, acuminate apically, reaching 5/6 length of tegumen. Phallus slender distally, weakly sclerotized, twisted in S shape; cornutus absent.

Female. Unknown.

Distribution. China.

Diagnosis. This new species resembles S. pseusta (Diakonoff) in the male genitalia, but can be separated from it by the brachia of uncus with basal half expanded to a sclerotized quadrate plate, the valvella with distal 1/7 expanded to a densely setose tuberculum, and the phallus without cornutus ( Fig. 40). In S. pseusta (Diakonoff) , the brachia of uncus are expanded in basal 1/4, the valvella is not tuberculum distally, and the phallus bears two cornuti.

Etymology. The specific epithet is derived from the Latin tuberculatus = tuberculum, in reference to the distal 1/7 of the valvella expanded to a tuberculum.
