Geographic Occurrence

Natural Resident: China, People's Republic of, Myanmar

Likely/Controversially Present: India


Closely related to Rana formosa according to the original publication. Transferred to Amolops by Dubois, 1974, Bull. Mus. Natl. Hist. Nat. Paris, Ser. 3, Zool., 213: 361, who suggested that it is probably a subspecies of Amolops formosus and that Staurois lifanensis Liu, 1945, is a junior synonym. These positions were rejected by Yang, 1991, Fieldiana, Zool., N.S., 63: 16. See comment under Amolops lifanensis. Sailo, Lalremsanga, and Hooroo, 2007, Herpetol. Rev., 38: 96, reported the species for Mizoram, India, but later suggested (Lalronunga, Vanramliana, Lalrinchhana, Vanlalhrima, Sailo, Lalnunhlua, Sailo, Zosangliana, Lalhmangaiha, and Lalhmingliani, 2020, Sci. Vision, 20: 106–117) that this identification needed to be confirmed with genetic analysis. In the Amolops viridimaculatus group of Jiang, Ren, Lyu, Wang, Wang, Lv, Wu, and Li, 2021, Zool. Res., Kunming, 42: 574–591. Zug, 2022, Smithson. Contrib. Zool., 653: 34, briefly discussed identification, habitat, and range in Myanmar. Mahony, Nidup, Streicher, Teeling, and Kamei, 2022, Herpetol. J., 32: 146, provided genetically-confirmed records for Pianma, Yunnan, China, and placed this species in the Amolops viridimaculatus group. Hou, Yu, Liu, Liu, Wang, Li, and Orlov, 2023, Russ. J. Herpetol., 30: 144–166, provided genetically confirmed records from Pianma and Dulongjiang, Yunnan, China.
