Comment

If (following Dubois, 1980, Bull. Mens. Soc. Linn. Lyon, 49: 469–482) Ophryophryne is considered a subgenus of Megophrys, Ophryophryne pachyproctus Kuo, 1985, becomes a secondary homonym of Megophrys pachyproctus Huang, 1981. Closely related to Ophryophryne microstoma according to the original publication. See accounts by Yang, 1991, Amph. Fauna of Yunnan: 66–67; Ye, Fei, and Hu, 1993, Rare and Economic Amph. China: 178; and Fei, 1999, Atlas Amph. China: 124–125. See comments by Inger, Orlov, and Darevsky, 1999, Fieldiana, Zool., N.S., 92: 8–9. Secondary homonym of Megophrys pachyproctus Huang, 1985, when in Megophrys. Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 84, noted reports of this species in Laos. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 86–87, provided a very brief account (as Ophryophryne microstoma), map for Thailand, and photograph. See account by Ohler, 2003, Alytes, 21: 34–39, who did not report this species from Laos. Nguyen, Ho, and Nguyen, 2005, Checklist Amph. Rept. Vietnam: 16, provided specific localities for Vietnam.
