This individual shows the characteristic dully-shiny black abdomen and reduced activity indicating a molt is about to occur (December 8, 2012). Click image to enlarge.
The molt took place on December 10, 2012. I was able to get the exoskeleton immediately after the molt. The clearly viewable spermathecae above the gonopore make clear that this individual is female. Thanks to Jen Newman and Paul Lawniczak for confirming gender. Click image to enlarge.
