Abstract
BACKGROUND: The new species, Harpiolaisodon Kuo et al., 2006, was described from Taiwan, China. So far, no distribution of this species outside Taiwan has been reported. NEW INFORMATION: During two field investigations of small mammals in Guanyin Mountains Provincial Nature Reserve, Yuanyang, Yunnan, China, in April 2022 and May 2023, five individuals of Harpiola were collected in the mid-montane evergreen broad-leaved forest. Our morphological and molecular results reveal that these individuals from the Chinese mainland belong to Harpiolaisodon, extending the occurrence of this species well beyond its known distributions in Taiwan, China and Vietnam.
