This is a male spider with light markings on the abdomen. This is the 5th spider of this species I've found in my backyard.
Originally from South America. It was introduced to the states in Fl and Tx. The scientific note was published in the The Pan-Pacific Entomologist in the Oct 2013 edition and the range was expanded to California.
