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 IN Frost, 1985, Amph. Species World: 503, who noted that Dubois had not examined specimens of Rana maculosa chayuensis. 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. 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. 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.
