M. robusta adult female - Marpissa robusta
Roseville, Placer County, California, USA
May 4, 2015
Found and identified by Tim Manolis, who gave it to me to photograph a few days later and preserve as a specimen - he says it was "beaten from cattails along the shore of a small, nearly dry pond in the floodplain of Secret Ravine". I'll add an epigynum photo soon.
