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.

[2] P. brevipes is distinguished from the similar Pisaurina mira by having relatively shorter legs.

The only records known to Carico seem to indicate that they favor grasslands, bogs, and swamps.

P. brevipes is difficult to distinguish from P. mira, unless the pedipalps of the males are examined.

[4] The reason is that its coloration patterns fall within the natural range of variation of the more numerous P.
