A New Species of Bolitoglossa ( Amphibia : Caudata : Plethodontidae ) from Montane Forests in Guatemala and El Salvador

Abstract

Previous molecular work on salamanders of the genus Bolitoglossa recognized the Magnadigita clade, which includes members of the Bolitoglossa dunni, Bolitoglossa franklini, and Bolitoglossa rostrata species groups. One well-supported clade within the B. dunni group includes Bolitoglossa celaque, Bolitoglossa synoria, and an undescribed taxon from El Salvador and Guatemala. I describe the last taxon as a new species based on published molecular evidence and morphological differences among closely related congeners. The new species is readily distinguished from B. celaque by dorsal coloration and from B. synoria by foot morphology.
