Rana chaochiaoensis Liu, 1946, J. West China Border Res. Soc., Ser. B, 16: 7. Holotype: CIB 609, by original designation. Type locality: "Chao-chiao-city, Ningshu, Sikang [= Zhaojue, Sichuan] province, China, 7200 ft. altitude". Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 3: 972, confusingly suggested CIB 641 is a lectotype; presumably this was intended as allotype.

Provisionally considered a member of the Rana temporaria group by Mensi, Lattes, Macario, Salvidio, Giacoma, and Balletto, 1992, Zool. J. Linn. Soc., 105: 293-311, although they suggested it may be closer to Rana arvalis. Resurrected from the synonymy of Rana japonica by Inger, Zhao, Shaffer, and Wu, 1990, Fieldiana, Zool., N.S., 58: 10, where it had been placed by Liu and Hu, 1960 "1959", Acta Zool. Sinica, 11: 509-533; and Liu and Hu, 1961, Tailless Amph. China: 180-181. Fei, 1999, Atlas Amph. China: 150-151, provided a brief account, map, and figure. China: 143. Zhao, Tan, and Wu, 1987, Acta Zootaxon. Sinica, 12: 213-218, suggested on the basis of karyological differences that Rana japonica and Rana chaochiaoensis were distinct species. Yang, 1991, Amph. Fauna of Yunnan: 127-129, provided an account. See comment under Rana japonica. Fei and Ye, 2001, Color Handbook Amph. Sichuan: 166, provided a brief account and illustration. Zhang and Wen, 2000, Amph. Guangxi: 78, provided an account (as Rana japonica) for Guangxi. See also brief account by Zhao and Yang, 1997, Amph. Rept. Hengduan Mountains Region: 85-86. Regarded as close to Rana omeimontis and in the Rana japonica group by Xie, Fei, and Ye, 2000, Cultum Herpetol. Sinica, 8: 74-80. In the Rana longicrus group of Fei, Ye, Huang, Jiang, and Xie, 2005, in Fei et al. (eds.), Illust. Key Chinese Amph.: 105. Li, Lu, and Li, 2005, Sichuan J. Zool., 24: 268-270, provided a distribution map for China. Yang, 2008, in Yang and Rao (ed.), Amph. Rept. Yunnan: 66-67, provided a brief account for Yunnan, China. Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 3: 972-977, provided an account for China and included it in their Rana longicrus group. Fei, Ye, and Jiang, 2010, Colored Atlas of Chinese Amph.: 264-265, provided a brief account including photographs of specimens and habitat. Yan, Jiang, Chen, Fang, Jin, Li, Wang, Murphy, Che, and Zhang, 2011, Asian Herpetol. Res., Ser. 2, 2: 67, suggested that this species is diagnosable on the basis of mtDNA evidence. Fei, Ye, and Jiang, 2012, Colored Atlas Chinese Amph. Distr.: 298–299, provided an account, photographs, and a range map for China.
