Comment

For purposes of priority Microhylidae takes the date 1843 from Hylaedactyli (based on Hylaedactylus [= Kaloula]) and Gastrophrynae (based on Gastrophryne; formerly a junior synonym of Microhyla) of Fitzinger, 1843, Syst. Rept.: 33, under the provisions of Article 40 of the International Code of Zoological Nomenclature (1999). Griffiths, 1963, Biol. Rev. Cambridge Philos. Soc., 38: 241-292; Lynch, 1973, in Vial (ed.), Evol. Biol. Anurans: 133-182; and Trueb, 1973, in Vial (ed.), Evol. Biol. Anurans: 65-132, placed Microhylidae phylogenetically near Ranidae; this view was disputed by Starrett, 1973, in Vial (ed.), Evol. Biol. Anurans: 251-271, on the basis of larval features, and by Savage, 1973, in Vial (ed.), Evol. Biol. Anurans: 351-445, who followed Starrett. Sokol, 1975, Copeia, 1975: 1-23, also studying larvae, disagreed with Starrett and concurred with more popular views; but see Pyburn, 1980, Pap. Avulsos Zool., São Paulo, 33: 231-238. Blommers-Schlösser, 1975, Beaufortia, 24: 14, noted that the morphological intermediacy of Scaphiophryninae supported the view that Microhylidae was most closely related to Ranidae (sensu lato). van der Meijden, Vences, and Meyer, 2004, Proc. R. Soc. London, B—Suppl. Biol. Lett., 271: S378-S381, showed that Brevicipitidae is not included in Microhylidae. Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, and Green, 2006, Bull. Am. Mus. Nat. Hist., 297, provided a discussion of taxonomic history, and also provided a partial revision of Microhylidae, evident here. (See comment under Microhylinae, in particular, for a summary of the changes suggested by these authors.) Accounts and keys to most of the genera are supplied by Laurent, 1986, in Grassé and Delsol (eds.), Traite de Zool., 14. Barker, Grigg, and Tyler, 1995, Field Guide Aust. Frogs., Ed. 2, provide keys and accounts for Australian species. Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 45-67, provided accounts and keys to the species of the Sunda Shelf. Malkmus, Manthey, Vogel, Hoffmann, and Kosuch, 2002, Amph. Rept. Mount Kinabalu: 115-116, provided a key to th genera of Borneo. See comment under Hemisotidae. Roelants, Gower, Wilkinson, Loader, Biju, Guillaume, Moriau, and Bossuyt, 2007, Proc. Natl. Acad. Sci. USA, 104: 887-892, provided evidence of phylogeny within Microhylidae, as did van der Meijden, Vences, Hoegg, Boistel, Channing, and Meyer, 2007, Mol. Phylogenet. Evol., 44: 1017-1030. Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 2: 868-957, provided accounts and spot maps for the species of China. Bossuyt and Roelants, 2009, in Hedges and Kumar (eds.), Timetree of Life: 357-364, considered the constituent subfamilies to be families on the basis of their suggested Mesozoic origins. Matsui, Hamidy, Belabut, Ahmad, Panha, Sudin, Khonsue, Oh, Yong, Jiang, and Nishikawa, 2011, Mol. Phylogenet. Evol., 61: 167-176, reported on the mtDNA phylogenetics of the Asian components of the family. On a much larger dataset (although relatively sparse sampling) Kurabayashi, Matsui, Belabut, Yong, Ahmad, Sudin, Kuramoto, Hamidy, and Sumida, 2011, BMC Evol. Biol., 11(175): 1-12, suggested a topology (Phrynomerinae +((Hoplophryninae +((Scaphiophryninae + Cophylinae) + Gastrophryninae) + (Kalophryninae + ((Gastrophrynoides + (Asterophryinae + (Dyscophinae + Microhylinae))))), including only their exemplars and showing some instability when Melanobatrachus is including in the analysis. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their study of Genbank sequences provided the largest analysis to date suggesting a topology of Phrynomerinae + (Otophryninae + ((Gastrophryninae + (Hoplophryninae + Cophylinae)) + (Scaphiophryninae + (Kalophryninae + (Asterophryinae + Melanobatrachinae)) + (Dyscophinae + Microhylinae))))); they also provided an extensive tree of species relationships that can be difficult to interpret given their adoption of an archaic nonmonophyletic taxonomy. Trueb, Diaz, and Blackburn, 2011, Phyllomedusa, 10: 99-135, reported on osteological characteristics of Gastrophryninae and Otophryninae. Blackburn and Wake, 2011, In Zhang (ed.), Zootaxa, 3148: 39-55, briefly reviewed the taxonomic history of this taxon. de Sá, Streicher, Sekonyela, Forlani, Loader, Greenbaum, Richards, and Haddad, 2012, BMC Evol. Biol., 12(241): 1-21, reported on the phylogenetics of the family, {Microhylinae + Dyscophinae}{Gastrophryninae [Asterophryinae (Cophylinae (Phrynomerinae (Otophryninae-Kalophryninae)))]}. They also redelimited a number of South American genera.Vitt and Caldwell, 2013, Herpetology, 4th Ed., provided a summary of life history, diagnosis, and taxonomy.
