Phalonidia rotundiventralis , sp. nov.

( Figs. 15 , 31 )

Type material. Holotype 3, CHINA: Wolong Nature Reserves, Wenchuan County (31°29ʹN, 103°36ʹE), Sichuan Province, 2008 m, 26.vii.2005, leg. Haili Yu, genitalia slide No. ZX06176.

Description. Adult ( Fig. 15 ). Wingspan 11.0 mm. Head: Vertex and frons pale yellowish brown. Antenna brown, with sparse brownish black scales. Labial palpus slender, about 1.5 times diameter of compound eye, yellow with sparse brown scales on outer surface, yellowish white on inner surface. Thorax: Pale brownish black; tegula brownish black, yellowish white distally. Forewing with costal margin nearly straight, apex protruded, termen oblique. Ground color pale yellowish white, except basal 1/5 ochreous yellow; costal margin with small brownish black spots, with a narrow brownish black stripe from base to inner margin of median fascia; median fascia brownish black with sparse ochreous yellow scales, extending obliquely from between basal 1/3 and 1/2 of costal margin to between basal 1/3 and 1/2 of dorsum, its inner margin slightly arched inward; subapical fascia grayish brown, inverted triangular, extending from distal 1/4 of costal margin to above tornus; a round patch above tornus, adjacent to inner margin of subapical fascia, pale yellow with sparse gray scales; pretornal spot at distal 2/5 of dorsum, yellow, triangular, anteriorly almost reaching outer margin of median fascia at middle; a small brownish black spot on dorsum beside outer margin of pretornal spot; dorsum with sparse brownish black scales; cilia grayish black with sparse pale yellowish white scales. Hindwing and cilia pale gray. Fore- and midlegs brownish black, with sparse yellowish white scales, tarsal segments with yellowish white rings; hindleg yellowish white, tarsal segments with sparse brownish black scales. Abdomen: Grayish brown. Male genitalia ( Fig. 31 ) with socii erect, fused in basal 3/5, separate in distal 2/5. Valva with basal 1/3 broad, distal 2/3 about 1/3 width of basal 1/3, parallel sided, apex rounded; costa reaching apex; transtilla gradually narrowed from base to middle, median process about 1/3 length of transtilla. Sacculus heavily sclerotized, almost same length as costa, length about three times width, ventral margin roundly protruding. Juxta nearly semicircular, bluntly rounded on anterior margin, straight on posterior margin. Phallus stout, about 1.5 times length of valva; cornutus slender, about 1/3 length of phallus, slightly dilated basally. Female unknown.

Diagnosis. This species is very similar to P. latifasciana in both facies and male genitalia, but P. rotundiventralis can be distinguished by the socii fused basally and separate distally, and the sacculus with the ventral margin roundly protruding in the male genitalia. In P. latifasciana , the socii are separate throughout, and the ventral margin of the sacculus is straight.

Distribution. China (Sichuan).

Etymology. The specific name is derived from the Latin rotundus (round), and ventralis (ventral), referring to the ventral margin of sacculus roundly protruding.

Diagnosis. Adult ( Fig. 17 ). Wingspan 14.0−16.0 mm. This species is very similar to P. melanothicta , but P. silvestris can be distinguished by the median process about 1/3 the length of the transtilla, the juxta triangularly protruded posterolaterally, and the phallus about 1.5 times the length of the valva in the male genitalia ( Fig. 33 ); by the ductus seminalis arising from the posterior part of the ductus bursae, the corpus bursae ovoid, without a sclerotized band in the female genitalia ( Fig. 45 ). In P. melanothicta the median process is about 1/2 the length of the transtilla, the juxta is straight on the posterior margin, and the phallus is slightly longer than the valva in the male genitalia; and the ductus seminalis arises from the anterior part of the ductus bursae, the corpus bursae is nearly rounded and bears a sclerotized band that forms an incomplete circle in the female genitalia.

Labial palpus about 1.5 times diameter of compound eye, yellowish brown with sparse brown scales on outer surface, pale yellowish white on inner surface. Thorax: Brownish black, mixed with yellowish brown; tegula brownish black mixed with yellowish brown except pale yellow distally. Forewing with costal margin slightly arched, apex protruded, termen somewhat oblique.

Valva broadest in basal half, gradually narrowed from middle to rounded apex; sclerotization of costa reaching apex; transtilla gradually narrowed from base to middle, median process narrow-triangular, about 1/2 length of transtilla.

In P. c o re an a, the socii are separate throughout, the ventral margin of the sacculus is sinuate, and the cornutus is about 1/3 length of the phallus in the male genitalia; and the ductus bursae is about 1/5 length of the corpus bursae in the female genitalia.

Distribution. China (Beijing, Tianjin).

Etymology. The specific name is derived from the Latin prefix tenui- (slender), and spiniformis (spinelike), referring to the slender spinelike cornutus.
