Comment

In the Hyla arborea group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 102 (see comment under Hyla), although it is likely to be a member of the Hyla eximia group (DRF). See Pope, 1931, Bull. Am. Mus. Nat. Hist., 61: 477–480, Liu and Hu, 1961, Tailless Amph. China: 128–130, and (as Hyla chinensis simplex) Bourret, 1942, Batr. Indochine: 224–226. See account by Ye, Fei, and Hu, 1993, Rare and Economic Amph. China: 205. Fei, 1999, Atlas Amph. China: 142–144, provided a brief account, map, and figure. Huang, 1990, Fauna Zhejiang, Amph. Rept.: 53–54, provided an account for Zhejiang populations. Zhang and Wen, 2000, Amph. Guangxi: 66, provided an account for Guangxi. Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 83, provided the Laos component of the range statement. Zhang, 2002, Sichuan J. Zool., 21: 198–199, provided a key to differentiate this species from others in China. Nguyen, Ho, and Nguyen, 2005, Checklist Amph. Rept. Vietnam: 18, provided specific localities for Vietnam. In the Hyla immaculata group of Fei, Ye, Huang, Jiang, and Xie, 2005, in Fei et al. (eds.), Illust. Key Chinese Amph.: 98, who provided a key to the subspecies. Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 2: 605–613, provided accounts by species and subspecies, illustrations of holotypes, and spot maps. Fei, Ye, and Jiang, 2010, Colored Atlas of Chinese Amph.: 256, provided brief accounts as Hyla simplex simplex and Hyla simplex hainanensis. Shi, 2011, Amph. Rept. Fauna Hainan: 45–46, provided an account for Hainan. Fei, Ye, and Jiang, 2012, Colored Atlas Chinese Amph. Distr.: 288–289, provided accounts (as Hyla simplex simplex and Hyla simplex hainanensis), illustrations, and a range map. Fei and Ye, 2016, Amph. China, 1: 854–859, provided accounts by subspecies, photographs, and spot maps for China. Li, 2011, Amph. Rept. Guangdong: 37, provided a brief account for Guangdong, China, and photograph. Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 28, suggested without providing evidence that records from China may actually correspond to Hyla zhaopingensis and that the Laos record requires confirmation. Not included in the list of Laotian fauna by Stuart, Seateun, Sivongxay, and Phimmachak, 2025 "2024", in Wildlife Lao PDR: 17–47, so excluded in this catalog.
