Baja California Treefrog
Pseudacris hypochondriaca (Hallowell, 1854)

Current SSAR Comments:
Recuero et al. (2006, Molecular Phylogenetics and Evolution 39: 293–304) recognized this species as distinct from P. regilla and composed of two subspecies, one of which is extralimital and whose mutual status is unclear. Barrow et al. (2014, Molecular Phylogenetics and Evolution 75: 78–90) suggested that the distinction between P. hypochondriaca and P. sierra, drawn based on mtDNA, was not supported by nDNA analysis. Through a mtDNA study with expanded geographic sampling, Jadin et al. (2021, Biological Journal of the Linnean Society 132: 612–633) found support for the species designations of Recuero et al. (2006, op. cit.) and refined range boundaries of the three taxa in this complex. The final resolution of this taxonomic question awaits nDNA analysis.
