Comment

Barbour, 1938, Proc. Biol. Soc. Washington, 51: 191-195, supplied synonymies and distributions in the sense of including what is now Rentapia. Graybeal and Cannatella, 1995, Herpetologica, 51: 123, noted that there is no unambiguous morphological evidence in support of the monophyly of this taxon. 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: 129, suggested on the basis of DNA sequence evidence that Pedostibes is most closely related to Phrynoidis. Smith and Chiszar, 2006, Herpetol. Conserv. Biol., 1: 6-8, implied that this taxon should be considered a subgenus of Bufo; see comment under Bufonidae. See comments under Sabahphrynus. Matsui, Yambun Imbun, and Sudin, 2007, Zool. Sci., Tokyo, 24: 1159-1166, corroborated a close relationship between Phrynoidis and Pedostibes. Van Bocxlaer, Biju, Loader, and Bossuyt, 2009, BMC Evol. Biol., 9 (e131): 1-10, noted that Pedostibes is polyphyletic, with their exemplar Pedostibes hosii being closely related to Duttaphrynus, but that Pedostibes tuberculosus is most closely related to a clade composed of Duttaphrynus and Adenomus. These authors suggested that the name Pedostibes will go with the group within which their exemplar Pedostibes tuberculosus falls (see below for resolution). Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their study of Genbank sequences, found Pedostibes tuberculosus (the name-bearer of Pedostibes) to be the sister taxon of a group composed of Schismaderma, Bufotes, Churamiti, Nectophrynoides, "Bufo" brongersmai, Xanthophryne, and Duttaphrynus. Another group of nominal Pedostibes (including their exemplars Pedostibes rugosus and Pedostibes hosii) was placed as the sister taxon of Phrynoidis. Instead of providing a taxonomic remedy, these authors embraced a polyphyletic Pedostibes and an explicitly non-monophyletic "Bufo". Ron, Mueses-Cisneros, Gutiérrez-Cárdenas, Rojas-Rivera, Lynch, Rocha, and Galarza, 2015, Zootaxa, 3947: 363, on the basis of 16s mtDNA analysis also concluded that Pedostibes is polyphyletic, suggesting that Pedostibes hosii and Pedostibes rugosus are more closely related to Phrynoidis and Pedostibes tuberculosus closer to Duttaphrynus + Xanthophryne, and suggested that the former two species could be transferred to Phrynoidis but declined to make the formal change. Subsequently, Chan, Grismer, Zachariah, Brown, and Abraham, 2016, PLoS One, 11(1): e0145903: 1–13, partitioned Pedostibes, restricting Pedostibes sensu stricto to India and referring the Sunda species to Rentapia.
