Abstract: Objective　To identify the species of a rodent sample captured in an imported container at the port of Zhejiang province, China. Methods　Morphological methods and DNA barcoding were applied for rodent identification. Results　The rodent had dark-brown fur with an approximate body length of 252 mm, a tail length of 220 mm, and a hind foot length of 40 mm. Genetic analysis of the mitochondrial cytB gene showed that the rodent shared the highest sequence homology with Bandicota indica and matched different individuals at a genetic distance of 0.048 to 0.175. Conclusion　Based on morphological characterization and DNA barcode comparison, the imported rodent sample was identified as B. indica. This species was captured for the first time at the port of Zhejiang province, which provided a reference to exclude invasion of exotic disease vectors.
