See accounts by Bourret, 1942, Batr. Indochine: 461–462; Liu and Hu, 1961, Tailless Amph. China: 274–275; Yang, 1991, Amph. Fauna of Yunnan: 190–191; and Fei, 1999, Atlas Amph. China: 254–257. Recorded for Thailand by Khonsue and Thirakhupt, 2001, Nat. Hist. J. Chulalongkorn Univ., 1: 77, and Nutphund, 2001, Amph. Thailand: 148; this requires confirmation. Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 93, commented on the Vietnamese distribution. Bain and Nguyen, 2004, Am. Mus. Novit., 3453: 22–24, provided the record for Ha Giang Province, Vietnam, and discussed the rationale for placing this species in Chirixalus. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 148–149, provided a very brief account (as Philautus gracilipes), map for Thailand, and photograph. Nguyen, Ho, and Nguyen, 2005, Checklist Amph. Rept. Vietnam: 35, provided specific localities for Vietnam (as Philautus gracilipes). Yang, 2008, in Yang and Rao (ed.), Amph. Rept. Yunnan: 102–103, provided a brief account (as Philautus gracilipes) for Yunnan, China. Mo and Zou, 2005, Herpetol. Sinica, 10: 89–92, reported the species in Guangxi, China, far from the localities in Yunnan. Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 2: 688–691, provided an account (as Aquixalus gracilipes) for China and spot map. Fei, Ye, and Jiang, 2010, Colored Atlas of Chinese Amph.: 425–383, provided a brief account (as Aquixalus gracilipes) including photographs of specimens and habitat. Fei, Ye, and Jiang, 2012, Colored Atlas Chinese Amph. Distr.: 506–507, provided an account (as Aquixalus idiootocus), photographs, and a range map for China. Rowley, Dau, Hoang, Nguyen, Le, and Altig, 2015, Amphibia-Reptilia, 36: 277–285, provided information on larval morphology and advertisement call. Li, 2011, Amph. Rept. Guangdong: 65, provided a brief account for Guangdong, China, and photograph. Matsui, Khonsue, Panha, and Eto, 2015, Zool. Sci., Tokyo, 32: 204–215, provided generically-confirmed records from Ha Giang and Lao Cai province, Vietnam, and also compared morphological characteristics with the similar Gracixalus seesomMakchai, Chuaynkern, Safoowong, Chuachat, and Cota, 2020, Amph. N. Thailand: 159, provided photographs, a brief account for Thailand, and a range map. Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 54, suggested for undisclosed reasons that Thailand records were based on misidentifications.
