sp. nov.

Yponomeuta zebra Sohn and Wu , n. sp.

( Figures 6, 8 View Figures 5–8 )

Type. HOLOTYPE: 1♀, Zhangmukoan [= Zhu Feng Nature Reserve], Tibet Autonomous Region, China, 12 VIII 1981 (SC Hu), genitalia slide no. IOZ-85-022 (attached to specimen) . Holotype is deposited in the Institute of Zoology , Chinese Academy of Sciences, Beijing, China .

Diagnosis. The new species shows closer affinity to Yponomeuta than two other similar genera, Teinoptilia and Ptiloteina by lack of a denticulated conical emargination on the signum of the female genitalia. Y. zebra n. sp. is the only species of Yponomeuta which has multiple black strips, instead of black dots, on the forewings.

Description. Head. Vertex rough with white piliform scales; frons white; chaetosema absent. Antenna filiform, 3/5 length of forewing; scape with white scales and pecten; flagellomeres white. Labial palpus upcurved, obtuse apically, white, with no scale tufts; second segment as long as third.

Thorax. Tegula white, with a black spot basally; mesonotum white, with a pair of black spots anteriorly, a pair of broad black transverse bars in middle. Foreleg with coxa white, with a black spot basally; femur white, with a broad black ring basally; tibia white, with a black spot medially, a black ring terminally; tarsi white, with a black ring on the distal end of each segment. Midleg with coxa white; femur white, with a black area basally; tibia white, with three black rings, each present basally, medially and terminally; tarsi white, with a black ring on the distal end of each segment. Hindleg with coxa white; femur white, with a black area basally; tibia white, with three black bands, each on base, basal third, termina; tibial tufts absent; tarsi white, with a black ring on the distal end of each segment. Forewing length 14.2 mm (n = 1), very elongate, moderately narrow, triangular, with a round apex and oblique termen; 18 longitudinal streaks extending from costa to dorsum, almost evenly spaced, irregularly disrupted by strigulae; fringes white, slightly tinged with gray on tornus. Hindwing slightly wider than forewing, gray, with a transparent, elliptical window near base, anal area lustrous white; fringes dark gray on costa, white along termen, yellowish gray on anal area.

Female genitalia ( Figure 8 View Figures 5–8 ). Papilla analis elongate, subtriangular, setose, longer than ninth abdominal segment; apophysis posterioris two times longer than apophysis anterioris; ventromedial area below papilla analis emarginated; lamella postvaginalis shallow, lobate, setose. Ostium bursae small; antrum long, cup-shaped. Ductus bursae tubular, enlarged to corpus, five times longer than corpus bursae. Corpus bursae oval; signum rhomboid, denticulated laterally and medially.

Distribution. China (southwest).

Etymology. The species epithet, zebra, is a noun in apposition, meaning the African horse with black stripe, which the forewing pattern of the new species resembles.

Supplementary or new records of the Chinese Yponomeutinae
