The species, Hypsiglena ochrorhyncha - Nightsnake, is found in a ring around the San Joaquin and Sacramento valleys, including the south coast ranges, and the inner north coast ranges and the foothills of the Sierra Nevada, and south into coastal Southern California.

Taxonomic Notes

The Society for the Study of Amphibians and Reptiles based their 2008 list of scientific and common names on Mulcahy (2006, PhD dissertation, Utah State University). Mulcahy conducted a comprehensive genetics study of Hypsiglena, recognizing 6 species, three in the USA, and an undescribed species. He also maintained several subspecies designations.

Grismer et al. (1994 Bulletin of the Southern California Academy of Science 93(2): 45-80) synonymized the Hypsiglena torquata subspecies deserticola and klauberi because they intergraded widely.
