locality, the spiders were found under stones lying on a large rock plateau with very sparse vegetation. Females were very abundant and did either not move upon turning the stone or ran a short distance and quickly stopped when reaching a small depression on the stone. Males appeared less abundant and were much quicker at escaping. Many females were carrying an egg sac.
