A new species of Caribbean toad (Bufonidae, Peltophryne) from southern Hispaniola.

Peltophryne armata sp. nov. is described from the South paleoisland of Hispaniola, West Indies.

Multilocus phylogeny of alligator lizards (Elgaria, Anguidae): Testing mtDNA introgression as the source of discordant molecular phylogenetic hypotheses.

The increased availability of nuclear DNA sequence data has led to a better appreciation of the role and frequency of introgressive hybridization and subsequent mitochondrial capture in misleading phylogenetic hypotheses based on mtDNA sequence data alone. Relationships among members of the alligator lizard genus Elgaria have been addressed with morphology, allozyme and mtDNA sequence data with discordant results. In this study, we use seven nuclear loci (total of 5.

Phylogenetics, classification, and biogeography of the treefrogs (Amphibia: Anura: Arboranae).

A phylogenetic analysis of sequences from 503 species of hylid frogs and four outgroup taxa resulted in 16,128 aligned sites of 19 genes. The molecular data were subjected to a maximum likelihood analysis that resulted in a new phylogenetic tree of treefrogs. A conservative new classification based on the tree has (1) three families composing an unranked taxon, Arboranae, (2) nine subfamilies (five resurrected, one new), and (3) six resurrected generic names and five new generic names.
