Abstract: Although the distribution of Rickett's big-footed bat (Myotis ricketti Thomas,1894) had been widely reported from Heilongjiang to Hong Kong,no distribution in Hainan Island is reported. The authors collected 27 specimens of Rickett's big-footed bat from Mt. Diaoluoshan and Huoshankou of Hainan Island in 2004,showing that Rickett's big-footed bat is widely distributed from Heilongjiang to Hainan Island,ranging from the northernmost to the southernmost parts in China. The measurements of specimens are less than those of the specimen collected from the mainland of China,and the authors
consider it may be necessary to study subspecies differentiation of the Hainan Island population.
