Hyliola cadaverina
California Treefrog, California Chorus Frog
family: Hylidae
subfamily: Hylinae
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.

Description
Adults attain a snout-vent length of 36mm in males and 45mm in females. This species has short slender arms, slender unwebbed fingers, small digital discs, and toes that are long, slender and 3/4 webbed. Dorsal surface is tuberculate, ventral surface is smooth to granular. Dorsal coloration is gray to brown with dark brown to green spots. Ventral coloration is dull grey to white on the throat and belly, and pale yellow on the groin, thigh, ventral surface of shank, and inner surface of the tarsus. There is a white line on the upper lip.

View distribution map using BerkeleyMapper.
Found in southwestern California and northwestern Baja California, Mexico; in the mountains and canyons from San Luis Obispo, California to Bahia de los Angeles, Baja California. This species occurs from the costal canyons east to the western edge of the Mojave and Colorado deserts. Found in elevations from near sea level to 1700m. Often found in riparian habitats.

Life History, Abundance, Activity, and Special Behaviors
A stream-dwelling population in the San Gabriel mountains was observed to use deep crevices away from the stream to hibernate for the winter.
