Abstract

Eight polymorphic microsatellite loci were identified in the Australian tree frog, Litoria ewingii, for studying patterns of hybridization with the closely related species L. paraewingi, using a microsatellite enriched genomic library. Across 55 individuals of L. ewingii and L. paraewingi, the mean number of alleles per locus was N a = 9.38 and N a = 7.13, respectively. All loci successfully cross-amplified in the remaining species in the Litoria ewingii complex, including the threatened sub-species L. verreauxii alpina. These loci will be useful in resolving species boundaries and exploring hybridization between species in the Litoria ewingii complex.
