Diagnosis. Pisaurina brevipes is distinguished from P. undulata 
and P. dubia by the nearly straight anterior eye row while the latter 
species have strongly procurved rows. It differs from the closely 
related P. mira by having a straight-bordered median dark band on 
the abdominal dorsum, and by having proportionally shorter legs. 
Description. Carapace: moderately high. Eyes: anterior row 
nearly straight. Legs: (2-1-4) -3. Abdomen: moderately long, less 
than twice length of carapace, often notched anteriorly. Pattern: 
rather homogeneous with distinct submarginal bands on carapace, 
dark median abdominal band with straight or nearly straight borders 
adjoining white narrow stripes, distinct dorso-lateral light bands 
adjoining white stripes; general color in darker areas reddish brown 
(Figs. 7, 8). male. Cymbium broad; conductor expanded distally 
with long, curved spine retrolaterally ; median apophysis bifid (Fig. 
14) ; embolus quite long, thin, arises proximally; patella-tibia I 
length/carapace length = 1.50 (only 2 specimens), female. Geni- 
talia as in Figs. 19, 20; patella-tibia I length/carapace length = 
ave. 1.25 (range 1. 13- 1.42). immatures. Body form, pattern sim- 
ilar to adults. 
Natural history. Nothing is found in the literature about the 
biology of this species; however, there are a few notes with the col- 
lections that were examined. Of three males in the collections, one 
was found in a meadow and one in a “prairie.” Only three biologi- 
cal notes were found with the females and were: “prairie,” “in 
bog near highway,” and “sweeping in swamp.” The two notes found 
with the immatures were: “walls of building” and “roadside ditch.” 
With this paucity of information, no distinction in habitat is made 
between this species and the closely related P. mira. 
Two of the males were collected in May; one in Ohio and one in 
Arkansas, while the third was collected in Florida on the fourth of 
March. Females were collected throughout the warmer season be-
