Cochylidia contumescens ( Meyrick, 1931)

( Figs. 3 , 13 )

Phalonia contumescens Meyrick, 1931: 157 . Type locality: Japan (Hokkaido, Sapporo). Cochylidia contumescens: Razowski, 1970: 376 ; Kawabe, 1982: 157; Byun, Park & Lee, 1996: 5; Byun, Bae & Park, 1998: 78; Brown, 2005: 200; Byun & Li, 2006: 791.

Material examined. CHINA: Tianjin Municipality: 13, Mt. Baxian, Ji County (40°02ʹN, 117°24ʹE), 110 m, 22.ix.2006, leg. Houhun Li. Anhui Province: 13, Wenquan Town, Yuexi County (30°52ʹN, 116°22ʹE), 7.viii.1995, leg. Xiangfu Hu. Henan Province: 23, Mt. Song, Dengfeng County (34°27ʹN, 113°02ʹE), 15−16.vii.2002, leg. Xinpu Wang. Guangxi Zhuang Autonomous Region: 13, Mulun Town, Huanjiang Maonanzu Autonomous County (25°08ʹN, 108°03ʹE), 280 m, 14.viii.2011, leg. Shulian Hao and Yinghui Sun.

Diagnosis. Adult ( Fig. 3 ) with wingspan 9.0−20.0 mm. This species is similar to C. oblonga Liu & Ge in genital structures, but C. contumescens can be distinguished by the median fascia of the forewing having a short grayish black stripe extending from the middle of the outer margin to above the tornus; the costal arm of the valva obliquely truncated at the apex, and the cornuti consisting of three thick spines about 1/2 the length of the phallus in the male genitalia ( Fig. 13 ). In C. oblonga , the median fascia has no stripe arising from the outer margin; the costal arm of the valva is bluntly rounded at the apex, and the cornuti are composed of 1−3 thin spines that are about 1/ 3 length of the phallus in the male genitalia. This species is also similar to C. altivaga Diakonoff, 1976 , and the differences between them are noted under the discussion of C. altivaga .

Distribution. China (Anhui, Guangxi, Henan, Tianjin), Korea, Japan, Russia.

Note. This species is recorded for the first time from China.
