English Names

Nicholls' Toadlets (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 94).


Extreme southwest of Western Australia.


Considered a synonym of Pseudophryne by Blake, 1973, Aust. J. Zool., 21: 119-149, this synonymy not accepted by Cogger, Cameron, and Cogger, 1983, Zool. Cat. Aust., Amph. Rept., 1: 20-21; without discussion. Resurrected from synonymy by Roberts and Maxson, 1989, Syst. Zool., 38: 154-165, who considered it the sister taxon of Myobatrachus. See Barker, Grigg, and Tyler, 1995, Field Guide Aust. Frogs., Ed. 2, for keys and accounts. Burton, 2001, Aust. J. Zool., 49: 539-559, suggested on the basis of foot muscles that Metacrinia is the sister taxon of Pseudophryne. Read, Keogh, Scott, Roberts, and Doughty, 2001, Mol. Phylogenet. Evol., 21: 294-308, suggested on the basis of mtDNA evidence that this taxon is the sister of Myobatrachus plus Arenophryne. 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, considered Metacrinia to be the sister taxon of Arenophryne. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their molecular study, suggested that Metacrinia is the sister taxon of Myobatrachus, but did not include Arenophryne in their analysis.
