The treefrogs (Hylidae) make up one of the most species-rich families of amphibians. With 885 species currently described, they contain >13% of all amphibian species. In recent years, there has been considerable progress in resolving hylid phylogeny. However, the most comprehensive phylogeny to date (Wiens et al., 2006) included only 292 species, was based only on parsimony, provided only poor support for most higher-level relationships, and conflicted with previous hypotheses in several parts (including the monophyly and relationships of major clades of Hylinae). Here, we present an expanded phylogeny for hylid frogs, including data for 362 hylid taxa for up to 11 genes (4 mitochondrial, 7 nuclear), including 70 additional taxa and >270 sequences not included in the previously most comprehensive analysis. The new tree from maximum likelihood analysis is more well-resolved, strongly supported, and concordant with previous hypotheses, and provides a framework for future systematic, biogeographic, ecological, and evolutionary studies. © 2010 Elsevier Inc.
