Pisaurina brevipes is a species of nursery web spider that is found in the eastern half of the North American continent from Ontario down to Florida and west to Kansas. These spiders are distinguished from the rather similar Pisaurina mira spiders by having relatively shorter legs. The ration of leg length I to cephalothorax length is less than 2.0 in males and less than 1.4 in females whereas for P. mira the leg length I is more than 2.0 in males and more than 1.4 in females.
