Adult female crab spider - Xysticus montanensis? - Xysticus montanensis - Female
Sign Hill Park, South San Francisco, San Mateo County, California, USA

Size: 4 mm
I beat this crab spider from a pine cone that was lying on the ground. It's an adult female and appears to be a Xysticus sp. The epigynum matches up quite well with X. montanensis, which Schick maps to my area of California. The spermathecae seem to match Schick's drawing pretty well, although they seem a bit different than the illustrations in Dondale and Redner and Paquin and Duperre...
