proximally; patella-tibia I length/carapace length = AVE. 2.21 
(range 2.02-2.45). (Fig. 13). female. Genitalia as in Figs. 17, 
18; patella-tibia I length/carapace length = AVE. 1.50 (range

Natural history. This is the most common species of the genus 
and is one of the most common spiders in eastern North America. 
Correspondingly, we have more natural history data pertaining to it 
than any other Pisaurina species.
