Male. Total length 4.24 ±0.26 mm; carapace 2.26 ±0.17 mm long 
and 1.67 ±0.11 mm wide (20 specimens). Carapace usually with 
yellow orange median and submarginal areas, and with paired dark, 
longitudinal bands flanking median area; margins usually pale. 
Sternum dark yellow or yellow brown, sometimes with small black 
spots along margins. Chelicerae pale yellow brown to black; 
retromargin with 3 teeth. Legs orange yellow; femur I (and 
sometimes II) often dark on basal three-fourths. Abdomen dull 
black, sometimes dull yellow mesally; venter pale yellow, sometimes 
with faint darker median band. Terminal apophysis with mesal 
swelling toothlike; median apophysis thick throughout most of its 
length, with basal process swollen (Fig. 24); conductor with single 
curve on basal margin, with dark, shiny knob near tip (Fig. 27). 
Female. Total length 5.05 ±0.55 mm; carapace 2.39 ±0.25 mm 
long and 1.79 ±0.13 mm wide (20 specimens). General color and 
structure as in male but paler. Median septum distinctly tapered 
anteriorly, with expanded posterior part concave at lateral margins 
(Fig. 65); copulatory tubes rather stout, with swellings on ventral 
surfaces (Figs. 66, 67). 
Diagnosis. Specimens of P. pauxilla differ from those of the other 
species in the milvina group by the toothlike swelling mesal to the
