This species occurs in far southern California and just over the border into Baja California, Mexico. EOO is estimated using GBIF (2017) as about 2,365 sq km.
Threat Impact Comments
The main threat listed for some CA occurrences is development. However, many occurrences list no threats because there is no documentation. We need more field revisits to refine the data for California and Baja California.
