Considered a synonym of Ixalus lateralis (now Leptolalax lateralis) by Gorham, 1974, Checklist World Amph.: 43, and Zhao and Adler, 1993, Herpetol. China: 119. Fei and Ye, 2000, Cultum Herpetol. Sinica, 8: 59-63, discussed the taxonomy of this species as well as its confusion with Ixalus lateralis Anderson, 1871, and noted that the stated distribution is highly provisonal. Much of the literature of this species refers to it erreoneously as Megophrys lateralis (e.g., Pope and Boring, 1940, Peking Nat. Hist. Bull., 15: 28; Bourret, 1942, Batr. Indochine: 199; Liu, 1950, Fieldiana, Zool. Mem., 2: 180; Dubois, 1980, Bull. Mens. Soc. Linn. Lyon, 49: 469-482; Rao and Yang, 1997, Asiat. Herpetol. Res., 7: 98; Dubois and Ohler, 1998, Dumerilia, 4: 14; Ye, Fei, and Hu, 1993, Rare and Economic Amph. China: 168, and Fei, 1999, Atlas Amph. China: 108-109; Sarkar and Ray, 2006, In Alfred (ed.), Fauna of Arunachal Pradesh, Part 1: 292-293). Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 83, commented on nomenclature and implicitly did not accept the arrangement of Fei and Ye, using instead the name Megophrys lateralis. See also brief accounts (as Megophrys lateralis) by Zhao and Yang, 1997, Amph. Rept. Hengduan Mountains Region: 43-44, and Dutta, 1997, Amph. India Sri Lanka: 37. Stuart, 2005, Herpetol.

Yunnan: 29-30, provided a brief account (as Megophrys lateralis) for Yunnan, China. Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 2: 370-376, provided an account and spot map for China.
