10. Eudonia zhongdianensis sp. n.

( Figs. 6 , 18 , 29 )

Type material. Holotype: 3, China: Zhongdian [Gyeltang or Gyalthang] (27°48ʹN, 99°42ʹE), Yunnan Province, 3150 m, 14.vii.2001, leg. Houhun Li and Xinpu Wang (genitalia slide No. LWC06002). Paratypes: 5 3, 3 ƤƤ, same data as holotype (genitalia slide Nos. LWC06013, LWC 060134, LWC08008, LWC08217).

Diagnosis. This species is similar to E. inouei Sasaki, 1998 in the male genitalia, but can be distinguished by the postmedian line conspicuously bending towards distal discoidal stigma and incurved at about posterior one third, and the subterminal line separated from postmedian line; and by the ductus bursae looped once anterior to the colliculum in the female genitalia. In E. inouei , the postmedian line inconspicuously bends towards distal discoidal stigma and the posterior two thirds is straight, and the subterminal line connects with postmedian line; and the ductus bursae is not looped. This species also resembles E. tibetalis ( Caradja, 1937) in the male genitalia, but can be disparted by the postmedian line incurved at about posterior one third, and the ductus bursae with a loop in the female genitalia. In E. tibetalis , the posterior one third of the postmedian line is straight, and the ductus bursae does not bear loop.

Description. Adult ( Fig. 6 ): Forewing length 8.5–9.0 mm. Frons pale brown. Vertex pale brown mixed with white. Labial palpus blackish brown; first segment white ventrally at base. Maxillary palpus blackish brown, white subbasally, apex white mixed with pale brown. Antenna with scapus pale brown dorsally, white ventrally; flagellomeres with dorsal surface pale brown and white, ventral surface pale brown. Patagium, thorax and tegula pale brown; posterior margin of tegula with long, pale brown-tipped white scales. Forewing covered with dense pale brown scales; antemedian line white, outcurve medially; antemedian stigmata blackish brown, stripelike, connected with antemedian line; distal discoidal stigma blackish brown, X-shaped; postmedian line white, meeting costa perpendicularly, conspicuously dentate towards distal discoidal stigma, incurved at about posterior one third, meeting dorsum by acute angle; subterminal line white, incurved medially, nearly parallel-sided with postmedian line; fringe pale brown, with white median line. Hindwing greyish white, apex and termen covered with sparse pale brown scales; fringe white, subbasal line pale brown. Abdomen pale brown to blackish brown, fourth to seventh segments lined with yellowish white on posteiror margin.

Male genitalia ( Fig. 18 ): Uncus ovate, notched at middle on posterior margin. Gnathos slender, bluntly rounded apically. Valva narrowed near base, then broadened to two thirds, distal one third narrowed towards rounded apex; costa straight. Juxta roundly dilated basally, narrowed towards blunt apex. Phallus curved slightly, nearly as long as valva.

Female genitalia ( Fig. 29 ): Papilla anale ovate, about two fifths length of apophysis posterior. Tergite eight half as long as apophysis anterior. Ostium bursae about twice as wide as colliculum. Antrum tubular, about one third length of colliculum; anterior one third covered with dense granules. Colliculum about one third length of ductus bursae. Ductus bursae looped before colliculum, slightly broadened towards corpus bursae. Corpus bursae rounded, covered with dense tiny spines; signum stripelike, placed at middle of corpus bursae; appendix bursae ovate, arising from anterolateral portion of corpus bursae.

Distribution. China (Yunnan).

Etymology. The specific name is derived from the type locality Zhongdian County (= Gyeltang or Gyalthang in Pinying, former name of Shangri-La County) in Yunan Province.
