English Names

Chinese Giant Salamander (Cochran, 1961, Living Amph. World: 20; Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 27; Fei, 1999, Atlas Amph. China: 38).

Distribution

The mountain streams of China, from Qinghai (see comment) to Gansu, southern Shanxi and south to Sichuan, Yunnan, Guangxi, and Guangdong, 100–1500 m elevation; likely introduced into Taiwan.

Comment

Synonymy and review (as Megalobatrachus davidianus) in Liu, 1950, Fieldiana, Zool. Mem., 2: 69-77.See accounts by Yang, 1991, Amph. Fauna of Yunnan: 28-30; Ye, Fei, and Hu, 1993, Rare and Economic Amph. China: 65; Fei, 1999, Atlas Amph. China: 38; Thorn and Raffaëlli, 2000, Salamand. Ancien Monde: 147-149; Fei, Hu, Ye, and Huang, 2006, Fauna Sinica, Amph. 1: 244-253; and Raffaëlli, 2007, Les Urodèles du Monde: 67-68. Huang, 1990, Fauna Zhejiang, Amph. Rept.: 17-18, provided an account for Zhejiang (as Megalobatrachus davidianus). Zhang and Wen, 2000, Amph. Guangxi: 19, provided an account for population in Guangxi, China. Fan, Guo, and Liu, 1998, Amph. Rept. Shanxi Prov.: 43-44, provided an account and the records for Shanxi, China. See also brief account by Zhao and Yang, 1997, Amph. Rept. Hengduan Mountains Region: 32. Zhao and Adler, 1993, Herpetol. China: 110, discussed the Taiwanese specimens. Lever, 2003, Naturalized Rept. Amph. World: 227, regarded the Taiwan population as introduced. Tao, Wang, Zheng, and Fang, 2005, Zool. Res., Kunming, 26: 162-167, reported on the genetic structure of four geographic populations of the species. Yang, 2008, in Yang and Rao (ed.), Amph. Rept. Yunnan: 16-17, provided a brief account for Yunnan, China. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 547. Fei, Ye, and Jiang, 2010, Colored Atlas of Chinese Amph.: 71, provided a brief account including photographs of specimen. Fei, Ye, and Jiang, 2012, Colored Atlas Chinese Amph. Distr.: 77, provided an account, photographs, and a map. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 86, provided a brief account, photo, and map.  Pierson, Yan, Wang, and Papenfuss, 2014, Amph. Rept. Conserv., 8: 1–6, could not find any Andrias in Qinghai, China, and suggested that populations were either nearly extirpated or completely so by stream quality degradation. Fei and Ye, 2016, Amph. China, 1: 259–252, provided an account, photographs, and range map. Yan, Lü, Zhang, Yuan, Zhao, Huang, Wei, Mi, Zou, Xu, Chen, Wang, Xie, Wu, Xiao, Liang, Jin, Wu, Xu, Tapley, Turvey, Papenfuss, Cunningham, Murphy, Zhang, and Che, 2018, Curr. Biol., 28: R590–R592, provided evidence that this nominal species is composed of several cryptic species, possibly as many as five, currently being mixed by the release of farm-raised animals likely resulting in species extinction via genetic homogenization. In the following article Turvey, Chen, Tapley, Wei, Xie, Yan, Yang, Liang, Tian, Wu, Okada, Wang, Lü, Zhou, Papworth, Redbond, Brown, Che, and Cunningham, 2018, Curr. Biol., 28: R592–R594, document the decline and extirpation of many of these populations in the wild.
