Which Black Widow? - Latrodectus hesperus

Which Black Widow? - Latrodectus hesperus
Tucson, Pima County, Arizona, USA
October 17, 2014
Found in the trunk of my car, along with its raggedy web. We had transported some nursery stock a week earlier. I assume this is a female, of the Lactrodectus genus. Is this a Western (Hesperus) or Brown (geometricus)Black Widow?
