Since 2004, we have surveyed birds in the southwest Guangxi Zhuang Autonomous Region of China. Many times during February, July, and October 2005 and January 2006, we observed, in Nonggang Natural Reserve of Guangxi, a species in the family Timaliidae that has never been recorded before in China or Southeast Asia. Nonggang Natural Reserve is located in the Sino-Vietnamese border region at 22°13′–22°34′N, 106°42′–107°05′E, 18 km southeast of the Vietnamese border. On 21 January 2006, we captured two individuals. Subsequent investigation showed that the specimens belonged to a previously undescribed species, which we designate Stachyris nonggangensis, the Nonggang Babbler.
