A new salamander of the genus Bolitoglossa (Caudata: Plethodontidae) from the highlands of western Panama.

We describe a new species of salamander of the genus Bolitoglossa from the Cordillera de Talamanca in western Panama. The new species is distinct from its congeners by its dorsal and ventral coloration, finger and toe webbing, and a comparatively high maxillary teeth count in relation to SVL. Analysis of mitochondrial DNA sequences revealed an isolated phylogenetic position of the new species which is related to the B.

A new rainfrog of the genus (Anura, Brachycephaloidea) from central and eastern Panama.

Substantial molecular and morphological character differences lead us to the description of a new species of the genus from the cloud forest of Cerro Chucantí, Maje Mountains, Darien Province, as well as from several other mountain ranges in eastern and central Panama. is a sister species to the allopatric group from northern Colombia with a mtDNA sequence divergence of > 4.4% at 16S and > 14.

A new species of (Amphibia: Bufonidae) from eastern Panama.

A new species of the genus , , from eastern Panama is described herein based on molecular, morphological, and bioacoustic evidence. The new species can be distinguished from its congeners occurring in the region by a combination of the following characters: (1) phalangeal reduction in thumb; (2) SVL (females only) (35.1-50.
