"Hylarana" montivaga — Provisional treatment here (version 6.0) due to not being assigned to any of the hylaranine genera by Oliver, Prendini, Kraus, and Raxworthy, 2015, Mol. Phylogenet. Evol., 90: 176–192. See comment. 

Odorrana montivaga — Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 50. Taxonomic arrangement based on undisclosed data from "Dubrovskaya et al., in press". I (DRF) sure hope Dubrovskaya was all right with this.

Comment

Prior to the revision of Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 297, placed in the Section Hylarana, subsection Hydrophylax, subgenus Sylvirana of Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 326. Allied with Rana varians, according to the original publication. See account by Bourret, 1942, Batr. Indochine: 346–348. See comment under Rana narina. See comments by Inger, Orlov, and Darevsky, 1999, Fieldiana, Zool., N.S., 92: 21. Thailand is included in range according to Khonsue and Thirakhupt, 2001, Nat. Hist. J. Chulalongkorn Univ., 1: 73, although this needs to be confirmed. Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 90, provided a statement of range. Stuart, 1999, in Duckworth et al. (eds.), Wildlife in Lao PDR: 48, reported the species in Laos but Stuart, 2005, Herpetol. Rev., 36: 477, noted the reidentification of the specimen as Huia nasica. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 132–133, provided a very brief account, map for Thailand, and photograph. Nguyen, Ho, and Nguyen, 2005, Checklist Amph. Rept. Vietnam: 30, provided specific localities for Vietnam. Oliver, Prendini, Kraus, and Raxworthy, 2015, Mol. Phylogenet. Evol., 90: 188, noted that this species is likely in either in Hydrophylax or Indosylvirana, but pending genetic sampling declined to make any taxonomic changes; here it is formally removed from Hylarana, which these authors rendered a monophyletic group. Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 51, considered the Thailand records to belong to Huia melasma for undisclosed reasons. Regardless, presence in Thailand requires confirmation.
