China: 176; and Fei, 1999, Atlas Amph. China: 124-125, for accounts. Thailand is range according to Khonsue and Thirakhupt, 2001, Nat. Hist. J. Chulalongkorn Univ., 1: 75, although this needs to be confirmed. Zhang and Wen, 2000, Amph. Guangxi: 51, provided an account for Guangxi. Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 84, noted that records exist for northern and eastern Laos. See account by Ohler, 2003, Alytes, 21: 31-34. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 86-87, provided a very brief account, map for Thailand, and photograph. Nguyen, Ho, and Nguyen, 2005, Checklist Amph. Rept. Vietnam: 15, provided specific localities for Vietnam (as both Ophryophryne poilani and Ophryophryne microstoma). Stuart, 2005, Herpetol. Rev., 36: 475, noted that the report for Laos (as Ophryophryne poilani) by Stuart, 1999, in Duckworth et al. (eds.), Wildlife in Lao PDR: 45, was based on Ophryophryne hansi.

Hist., 2010: 38, provided a record for northeastern Cambodia (as Ophryophryne poilani) and disputed the synonymy as well as documenting sympatry Ophryophryne hansi.
