Abstract:[Aim] In July 2016, a specimen of the ant Polyrhachis bicolor Smith, 1858 was collected and identified by the Plant Quarantine Lab of Beijing Entry-Exit Inspection and Quarantine Bureau, in a mangosteen shipment from Thailand. This is the first interception record for China. Understanding the situation of Polyrhachis can provide basis for the quarantine and identification of the insects.[Method] By collecting and translating references, we discribed the taxonomic status, distribution, morphologiacal characteristics and similar species of P. bicolor. The species of the genus Polyrhachis in China were introduced, and the intercept situation of the genus were analyzed.[Result] P. bicolor (Hymenoptera:Formicidae) distributed mainly in southeast Aisa and Austrilia, it distributed only in Yunnan Province in China. Forty-five species and 1 subspecies of Polyrhachis were known in China. A total of 2097 batches of Polyrhachis were found in the quarantine system from 2003 to July 2016.[Conclusion] Polyrhachis are most likely to invade by cargo container. The departments of entry and exit should strengthen quarantine work on the insects.
