North China Tree Toad (Boring, Liu, and Chou, 1932, Handb. N. China, Amph. Rept.: 29).

Suweon Treefrog (Hyla suweonensis [no longer recognized]: Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 58; Yang, Kim, Min, and Suh, 2001, Monogr. Korean Amph.: 52).


Eastern-central China (Anhui, Fujian, Guizhou, Guangdong, Hebei, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Shandong, Sichuan, Zhejiang) and another population in Kyonggi-Do and part of Chung-chung-Do, in northwestern South Korea, presumably extending into southwestern North Korea. 


In the Hyla arborea group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 101-102 (see comment under Hyla). In the Hyla immaculata group of Fei, Ye, Huang, Jiang, and Xie, 2005, in Fei et al. (eds.), Illust. Key Chinese Amph.: 99. Hua, Fu, Li, Nieto-Montes de Oca, and Wiens, 2009, Herpetologica, 65: 246-259, presented molecular evidence for its placement in the Hyla japonica group; this confirmed by  Li, Wang, Nian, Litvinchuk, Wang, Li, Rao, and Klaus, 2015, Mol. Phylogenet. Evol., 87: 80–90. See account (as Hyla arborea immaculata) by Liu and Hu, 1961, Tailless Amph. China: 127-128, Ye, Fei, and Hu, 1993, Rare and Economic Amph. China: 186.

Huang, 1990, Fauna Zhejiang, Amph. Rept.: 49, provided an account (as Hyla arborea immaculata) for Zhejiang populations. Zhang, 2002, Sichuan J. Zool., 21: 198-199, provided a key to differentiate this species from others in China. Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 2: 595-600, provided an account and spot map. Fei, Ye, and Jiang, 2010, Colored Atlas of Chinese Amph.: 254-255, provided a brief account including photographs. Fei, Ye, and Jiang, 2012, Colored Atlas Chinese Amph. Distr.: 286, provided an account, illustrations, and a range map. See also Lee and Park, 1992, Korean J.
