摘要

The genus Biston Leach, 1815 is reviewed for China. Seventeen species are recognized, of which Biston mediolata >sp. n. is described. Biston pustulata (Warren, 1896) and Biston panterinaria exanthemata (Moore, 1888) are newly recorded for China. The following new synonyms are established: Biston suppressaria suppressaria (Guenée, 1858) (= Biston suppressaria benescripta (Prout, 1915), >syn. n. = Biston luculentus Inoue, 1992 >syn. n.); Biston falcata (Warren, 1893) (= Amphidasis erilda Oberthür, 1910, >syn. n. = Amphidasis clorinda Oberthür, 1910, >syn. n. = Biston emarginaria Leech, 1897, >syn. n.); Biston panterinaria panterinaria (Bremer & Grey, 1853) (= Biston panterinaria abraxata (Leech, 1889), >syn. n. = Biston panterinaria lienpingensis (Wehrli, 1939), >syn. n. = B. panterinaria szechuanensis (Wehrli, 1939), >syn. n.). Biston falcata satura (Wehrli,1941), >comb. n. is proposed. A key to Chinese Biston and diagnoses for Chinese species are provided. Illustrations of external features and genitalia are presented.
