Comment

Dubois, 1980, Bull. Mens. Soc. Linn. Lyon, 49: 142-147, placed Rana maculosa chayuensis Ye, 1977 (of southern Xizang, China), into the synonymy of Rana arnoldi (= Nanorana arnoldi of this catalog). This synonymy was rejected by Hu, 1985, in Frost (ed.), Amph. Species World: 503, who noted that Dubois had not examined specimens of Rana maculosa chayuensis. Yang, 1991, Amph. Fauna of Yunnan: 118–120, provided an account (as Nanorana arnoldi). Separate species status for Rana chayuensis was accepted subsequently by Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 320, although the synonymy was accepted, without comment, by Zhao and Adler, 1993, Herpetol. China: 138. See account by Ye, Fei, and Hu, 1993, Rare and Economic Amph. China: 277; and Fei, 1999, Atlas Amph. China: 212-213. Fei and Ye, 2001, Acta Zool. Sinica, 47: 226-230, compared this species with Paa medogensis and Paa arnoldi and considered it to be distinct. See also brief account (as Rana arnoldi) by Zhao and Yang, 1997, Amph. Rept. Hengduan Mountains Region: 83–84 (now reassigned to Nanorana chayuensis). Li, Lu, Li, Zhao, Hou, and Zhang, 2005, Sichuan J. Zool., 24: 248, provided additional localities in Xizang. Deuti and Ayyaswamy, 2008, Herpetol. Rev., 39: 234, provided a record for Neora Valley National Park, Darjeeling District, West Bengal, India, 1850 m elevation. Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 630, implied that this may be a junior synonym of Nanorana annandalii. Yang, 2008, in Yang and Rao (ed.), Amph. Rept. Yunnan: 82–83, provided a brief account (as Paa arnoldi) for Yunnan, China. Records of Nanorana arnoldi from Yunnan, China, were reassigned to Nanorana chayuensis by Che, Hu, Zhou, Murphy, Papenfuss, Chen, Rao, Li, and Zhang, 2009, Mol. Phylogenet. Evol., 50: 59–73, according to Yuan, Chen, Wu, Li, and Che, 2022, Biodiversity Sci., 30 (4: 21470): 6. Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 3: 1401-1406, provided an account (as Paa chayuensis) for China, figures, and map, and included this species in their Paa maculosa group. Fei, Ye, and Jiang, 2010, Colored Atlas of Chinese Amph.: 363-364, provided a brief account for China including photographs of specimens and habitat. Fei, Ye, and Jiang, 2010, Colored Atlas of Chinese Amph.: 362-363, provided a brief account (as Paa chayuensis) for China. Li, Zhao, and Dong, 2010, Amph. Rept. Tibet: 40-41, provided an account (as Paa chayuensis) for Xizang, China. Fei, Ye, and Jiang, 2012, Colored Atlas Chinese Amph. Distr.: 452-453, provided an account (as Maculopaa chayuensis), photographs, and a range map for China. Tang, Liao, Peng, Jiang, You, and Chen, 2020, MtDNA, Part B, 5: 772–773, reported on the mtDNA genome. Che, Jiang, Yan, and Zhang, 2020, Amph. Rept. Tibet: 255–260, provided a detailed account for Tibet, China. Zug, 2022, Smithson. Contrib. Zool., 653: 23–24, briefly discussed identification, habitat, and range in Myanmar.
