I am 100% certain of this location, and the identification seems very certain. I think this might be important, as it is a very rare species only found alive a few times in the last 6 years. the shape matches a species found in Australia. If it's that species, how did it get here? If it's the California native species, could this be an extended range? Introduced? New species, even??
