Abstract：The Distribution of butterflies ( Lepidoptera:Rhopalocera) in Gansu’s Taitong-Kongtongshan National Nature
Reserve was studied from 2006 to 2010． Identification of about 4 800 specimens indicated that 230 species and subspecies
of butterflies from 10 families，24 subfamilies and 126 genera were obtained． The Nymphalidae，with 71 species
comprising 30. 87% of the total，were the dominant group． The Satyridae and Lycaenidae were represented by 46 species
and 37 species，respectively comprising 20. 0% and 16. 1% of the total． Both the Libytheidae and Riodinidae were
represented by just one genus and one species． Palearctic species comprised 26. 5% of the 230 species identified，
Oriental species 5. 7% and widely distributed species 67. 8% ． 75 of the 126 genera，59. 5% of the total，were
monotypic，containing species that comprised 32. 6% of the total． Fifty-one genera，40. 5% of the total，were polytypic，
containing 155 species or 67. 4% of the total． The ratio of genera to species was 0. 548． The results show that the butterfly
fauna of this region is mainly comprised of monotypic genera．
