English Names

Distribution

Known with assuredness only from Vietnam (Quang Thanh, Cao Bang province; Tam Dao, Vinh Phuc province, Sa Pa, Lao Cai province, and Hai Ha District, Quang Ninh Province) and China (Xiaoqiaogou Nature Reserve, Yunnan; Malipo, Yunnan); Tale Valley Wildlife Sanctuary, Arunachal Pradesh, northeastern India. See comment. 

Comment

Removed from the synonym of Megophrys major by Chen, Zhou, Poyarkov, Stuart, Brown, Lathrop, Wang, Yuan, Jiang, Hou, Chen, Suwannapoom, Nguyen, Duong, Papenfuss, Murphy, Zhang, and Che, 2017, Mol. Phylogenet. Evol., 106: 32, where it had been placed by Bourret, 1942, Batr. Indochine: 199. Treated as distinct by Mahony, Foley, Biju, and Teeling, 2017, Mol. Biol. Evol., 34: 755, but this manuscript was submitted before the appearance of the paper by Chen et al., 2017. Saikia, Sinha, Thakur, and Kharkongor, 2019, Rec. Zool. Surv. India, 119: 456–462, provided the Arunachal Pradesh, India, record, confirmed by 12S and 16S mtDNA barcoding. Tapley, Nguyen, Cutajar, Nguyen, Portway, Luong, and Rowley, 2020, Zootaxa, 4845: 35–52, provided a detailed description of larval morphology. In the Xenophrys major group of Lyu, Zeng, Wang, Liu, Huang, Li, and Wang, 2021, Zootaxa, 4927: 9–40. Pham, Do, Ngo, Tran, Ziegler, and Nguyen, 2020, Check List, 16: 1025–1041, provided a record from Hai Ha District, Quang Ninh Province, Vietnam, on the Guangxi, China, border. Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 36, suggested that likely all records of nominal Xenophrys major from Vietnam, Cambodia, and Laos apply to this species; see the Xenophrys major for access to a large confusing literature.
