Comment
See account by Bourret, 1942, Batr. Indochine: 170–172, and Dubois and Ohler, 1999, J. South Asian Nat. Hist., 4: 133–180 (who placed it in their Bufo stejnegeri group). See comment under Bufo burmanus. Liu, Lathrop, Fu, Yang, and Murphy, 2000, Mol. Phylogenet. Evol., 14: 433, noted that Bufo pageoti is most closely related to species formerly placed in Torrentophryne. Bufo burmanus was placed in the Bufo melanostictus group (now Duttaphrynus) according to Inger, 1985, in Frost (ed.), Amph. Species World: 38, this disputed by Dubois and Ohler, 1999, J. South Asian Nat. Hist., 4: 136 (who retained it in Bufo), both assignments based apparently on perceptions of overall similarity. Subsequently Bufo burmanus was placed in the Bufo cryptotympanus group (= Bufo stejnegeri group of Dubois and Ohler, 1999, J. South Asian Nat. Hist., 4: 133–180) according to Hu, Jiang, and Tian, 1984, Acta Herpetol. Sinica, Chengdu, N.S.,, 3 (1): 77–85. Yang, 1991, Amph. Fauna of Yunnan: 97–98, and Fei, 1999, Atlas Amph. China: 126–127, provided a brief account, figure, and map. 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, suggested that this species is not a member of the monophyletic taxon Bufo (the former Bufo bufo group), but could not allocate this species to any of the other genera either, instead leaving this species in a non-taxon "Bufo" which they denoted as non-monophyletic by placing the name in quotation marks. Yang, 2008, in Yang and Rao (ed.), Amph. Rept. Yunnan: 56–57, provided a brief account (as Torrentophryne burmanus) for Yunnan, China. See statement of geographic range, habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 611. Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 2: 580–585, provided an account (as Torrentophryne burmana) and spot map. Fei, Ye, and Jiang, 2010, Colored Atlas of Chinese Amph.: 208–209, provided a brief account (as Torrentophryne burmanus) including photographs. Fei, Ye, and Jiang, 2012, Colored Atlas Chinese Amph. Distr.: 271, provided an account (as Torrentophryne burmanus), photographs, and range map for China. Fei and Ye, 2016, Amph. China, 1: 811–802, provided an account, photographs, and spot map for China, as Torrentophryne burmanus, without addressing the earlier synonymy with Bufo pageoti. Liedtke, Müller, Rödel, Menegon, Gonwouo, Barej, Gvoždík, Schmitz, Channing, Nagel, and Loader, 2016, Evolution, 70: 1717–1733, Supporting Inform. S4, placed this species within the Duttaphrynus clade, as did Othman, Chen, Chuang, Andersen, Jang, and Borzée, 2020, Animals, 10 (1157) : 1–24 (see figure 2). Zug, 2022, Smithson. Contrib. Zool., 653: 14, discussed identification, habitat, and range in Myanmar (as Bufo pageoti). Othman, Litvinchuk, Maslova, Dahn, Messenger, Andersen, Jowers, Kojima, Skorinov, Yasumiba, Chuang, Chen, Bae, Hoti, Jang, and Borzée, 2022, eLife, 11(e70494): 1–42, recovered the species within Bufo. Portik, Streicher, and Wiens, 2023, Mol. Phylogenet. Evol., 188 (107907): 68, also recovered the species in Duttaphrynus (sensu lato, in what is now including Firouzophrynus). Given the analytical instability of this terminal DRF provisionally retains this species in Bufo, but notes that short of a catastrophic failure of record-keeping the only other Duttaphrynus (sensu lato) within the range of Bufo pageoti is Duttaphrynus melanostictus and this sequence clearly is not of that species.
