The ants intercepted from Thailand on Lansium domesticum were identified by morphological characters. According to the information of website http://info.apqchina.org/, P. notiala was intercepted for the first time at China's ports. P. notiala was described by Zhou and Zheng in 1998, and previously was considered a species endemic to Guangxi, China. This is a new record from Thailand. Through morphological characters of worker and queen, differences between two closely related species and illustrations of Philidris notiala Zhou & Zheng, and the species list and distribution of Philidris were provided in order to provide reference for port quarantine, distribution and control.
