A new species of diminutive salamander (Amphibia: Caudata: Plethodontidae: Nototriton} from the Montanas del Mico of Guatemala

摘要

Nototriton stuarti, a new species of salamander belonging to the tribe Bolitoglossini, family Plethodontidae, is described from the Montanas del Mico, north of the Motagua Valley, in eastern Guatemala. The species is geographically isolated from congeneric species, and represents the northwestern-most record for the genus, which ranges from eastern Guatemala to central Costa Rica. This poorly known species is morphologically most similar to Nototriton barbouri, which occurs in northwestern Honduras.
