Taxonomic studies of Taiwan moths have been done by only a few Taiwanese and foreign entomologists. The earliest significant collections and studies of Taiwan Lepidoptera began in 1856 with the arrival of Robert Swinhoe (1836-1877) as British Consul in Taiwan. The Japanese Occupation (Sino-Japanese War of 1895-1945) enabled studies by mainly Japanese scientists, and post- 1945 many Japanese and some others scientists visited Taiwan to study and collect moths and butterflies. In 1992, Heppner and Inoue (eds.) reported over 3,900 species in the checklist of "Lepidoptera of Taiwan" for the first time, based on the materials from 62 collecting sites and previous records. Recently,the Lepidoptera series of guide books to Insects in Taiwan was published by Mr. H.Y. Wang. Also the 2nd author has a publication plan of a total of 10 volumes in the series of "Lepidoptera of Taiwan", and a color introduction due out this year. In this study, we identified over 3,000 specimens of the subfamily Olethreutinae belonging to the family Tortricidae, collected at 62 sites in Taiwan from 1982 to 2006 by the 2nd author and some of collection’s of Y.S. Bae and K. T. Park in 1996-1999. We recognize the results of identification that more than 280 Taiwan tortricids, including over 35 newly recorded or new species, are in the Taiwan fauna.
