Pacific Treefrog, Pacific Chorus Frog
|Taxonomic Notes: Duellman and colleagues (http://doi.org/10.11646/zootaxa.4104.1.1) propose resurrecting the unused name Hyliola for western tree frogs (Pseudacris regilla and cadaverina). The western species have been in Pseudacris for only 10 years, so the least destabilizing and likely most robust taxonomic move is to recognize three genera: Acris, Hyliola and Pseudacris. Recuero et al. (2006, Mol Phylog Evol), on the basis of limited mtDNA data and some old allozyme information, divided this taxon into three: P. hypochondrialis in Baja California and southern California, P. sierra in central California, and restricted P. regilla to northwestern California and more northerly regions. However, central Calfornia was poorly sampled and it is impossible to determine the borders of the putative species. Furthermore, there are irregularities in the distribution of mtDNA haplotypes that call the taxonomic decisions into question. The entire complex badly needs to be studied using fine scale sampling and nuclear gene sequences.|
