Pseudacris regilla (Baird & Girard, 1852) Pacific Treefrog, Pacific Chorus Frog Subgenus: Hyliola	family: Hylidae subfamily: Hylinae genus: Pseudacris
Species Description: Baird, S. F., Girard, C. (1852). "Descriptions of new species of reptiles, collected by the U.S. Exploring Expedition under the command of Capt. Charles Wilkes, U.S.N., First Part—including the species from the western part of America." Proceedings of the Academy of Natural Sciences of Philadelphia 6, 174–177.
Taxonomic Notes: Duellman, Marion, and Hedges (2016) proposed resurrecting the unused name Hyliola for western North American tree frogs Pseudacris regilla and P. cadaverina. Faivovich et al. (Faivovich J, Pereyra MO, Luna MC, Hertz A, Blotto BL, Vasquez-Almarzan CR, McCranie JR, Sanchez DA, Baeta D, Araujo-Vieira K, Kohler G, Kubicki B, Campbell JA, Frost DR, Wheeler WC, and Haddad CFB. 2018. On the monophyly and relationships of several genera of Hylini (Anura: Hylidae: Hylinae), with comments on recent taxonomic changes in hylids. South American Journal of Herpetology 13:1-32.) says: "All results published in the last 12 years obtained the P. cadaverina + P. regilla clade as the sister taxon of the remaining species of Pseudacris. As such, the resurrection of Hyliola is both congruent with our phylogenetic knowledge, and optional on the same grounds. Given the optional nature of the recognition of Hyliola and the lack of any substantial discussion as to its taxonomic utility, we see no reason to follow it." Recuero et al. (2006, Mol Phylog Evol) on the basis of limited mtDNA and old allozyme data, divided this taxon into three: P. hypochondriaca in Baja California and southern California, P. sierra in central California, and P. regilla restricted to northwestern California and more northerly regions. However, central California 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 decision into question. The entire complex badly needs to be studied using fine scale sampling and nuclear gene sequences.
