Eleven tetranucleotide microsatellite loci were developed for the Del Norte salamander (Plethodon elongatus). The loci were variably polymorphic, ranging from two to 20 alleles per locus, with expected heterozygosities ranging from 0.07 to 0.86. The loci also amplified in a congener, the Siskiyou Mountain salamander (P. stormi). The microsatellite loci will be used to assess the utility of highly polymorphic markers to assay within- and between-species differentiation between these two closely related species.
