Zool., 54: 135, reported the species in Cambodia and who noted that the animal pictured of the holotype in the original publication was neither the holotype nor a specimen of Ophryophryne hansi. See comments by Inger, Orlov, and Darevsky, 1999, Fieldiana, Zool., N.S., 92: 9 (as Ophryophryne poilani). Stuart, 2005, Herpetol. Rev., 36: 475, provided records for Laos.
