<p> <strong>Abstract </strong><br /> Based on a molecular phylogeny, a new phylogenetic taxonomy that is compatible with both the International Code of <br /> Zoological Nomenclature (ICZN) and the PhyloCode is proposed for Glassfrogs and their sister taxon, Allophryne <br /> ruthveni. The arrangement presented herein emphasizes the recognition of clades having (i) significant statistical support <br /> and congruence among phylogenetic estimation methods (i.e., parsimony, maximum likelihood, and Bayesian inference <br /> criteria), (ii) congruence among genetic markers, and (iii) morphological and/or behavioral distinctiveness. Also, when <br /> previously recognized groups are recovered as monophyletic or nearly monophyletic, we propose taxa that minimize the <br /> number of name changes required to make these groups monophyletic, preserving the names and contents of previous <br /> classifications (i.e., nomenclatural stability). The evolutionary proximity of Centrolenidae and Allophrynidae is <br /> recognized by combining these families into an unraked taxon, Allocentroleniae&mdash;a proposal that maintains the <br /> traditional names and species contents of Centrolenidae and Allophrynidae. We arrange centrolenid diversity in two <br /> subfamilies: Centroleninae and Hyalinobatrachinae. Within Centroleninae, the diagnosis and species content of the <br /> genera Centrolene, Cochranella, and Nymphargus are modified; Teratohyla is resurrected and modified, and Chimerella, <br /> Espadarana, Rulyrana, Sachatamia, and Vitreorana are proposed as new genera. The other subfamily, <br /> Hyalinobatrachinae, contains the new genus Celsiella and a modified Hyalinobatrachium that fully corresponds to the <br /> former fleischmanni Group. Additionally, the genus Ikakogi is described. Ikakogi could not be assigned with confidence <br /> to either subfamily and it is placed as incertae sedis in Centrolenidae. The data at hand suggest that Ikakogi tayrona is a <br /> lineage as old as the subfamilies Hyalinobatrachinae and Centroleninae. The revised taxonomy differs markedly from <br /> previous arrangements, which were based on phenetics and few morphological characters. Most of the genera defined <br /> herein are confined to distinct biogeographic regions, highlighting the importance of geography in the speciation of <br /> Glassfrogs. The principal limitation of this proposal is that it is based on an incomplete sampling of taxa (54% of the <br /> recognized Glassfrogs). Although diagnoses are based on phenotypic traits, there are several cases (16% of all species) in <br /> which the allocation of species is ambiguous because of morphological homoplasy and the lack of molecular data. <br /> Finally, in an attempt to facilitate species identification, comparison, and generic placement, we provide photographs for <br /> most (~ 96%) of the recognized centrolenid species. </p> <p> <br /> <strong>Key words: </strong> </p> <p> Allophrynidae, Amazon, Andes, Anura, Centrolenid frogs, Classification, Cordillera de la Costa, Central <br /> America, Diversity, Guiana Shield, Hyloidea, Neobatrachia, Neotropics, Phylogeny, South America, Systematics </p>
