Length, 2 5-6 mm., / 7-10 mm. Legs, $ 1342. 2 4312. 
Spines $ and 2, tibia I 2-2 and 2-2 bulbous hairs, tibia 
II, 1-1, 1 below and 1 ant. lat. Sometimes the two unpaired 
spines are lacking. 
The general color of the male is like sylvana, but instead of 
the oval white spot there is a white band running from between 
the dorsal eyes down the thoracic slope; under the dorsal eyes 
there is a white band instead of the three lines, and there is 
only one white line on each side coming up from the lower 
margin. The differences in the markings and the smaller size 
readily distinguish it from sylvana. 
The female can be distinguished from sylvana only by its 
smaller size, the slight difference in the spines of the second 
tibia and the epigynum. 
The tooth on the lower border of the falx, in both sexes, is 
commonly compound, occasionally simple, and sometimes there 
are several teeth.
