Spines are so slender that they may be termed spinules. Trichobothria 
observed on tibiae and metatarsi; apparently not restricted to one 
dorsal unit on metatarsi as stated by the author of the species with 
respect to the male. 
Abdomen. Essentially as described for the male. Total length of 
abdomen 2.4; almost as tall as long and with the same width in the 
middle. 
Epigynum. Rather distinctive; features best shown in Figures 1-3. 
Color in alcohol. Carapace yellowish with two large white patches 
near the middle, made by sub-chitinous deposits; with the usual black 
pigment surrounding the eyes. Sternum bright reddish. Chelicerae a 
light reddish brown ; other mouth parts about the same but with 
whitish margins. The legs are colored essentially as described for the 
holotype male, but I have noted minor variations; first, second and 
fourth tarsi are black; the third tarsus is black in the distal half, 
yellowish in the proximal half. The anterior tibiae have a black and 
red distal transverse band. The abdomen is basically white dorsallv 
and dorsolaterally with multiple hieroglyphic-like lines and bars of 
many different shapes and lengths; all of these are in red contrasted 
to the black hieroglyphs described in the male holotype. A great vari- 
ation in the abdominal color pattern has been noted among the numer- 
ous specimens now available for study. Some of these have the hiero- 
glyphs almost devoid of color; others have them in a mixture of red 
and black ; still others run largely to black or red ; this would also be 
true for males as well as females ; the venter is basically yellowish with 
a superimposed reddish tint increasing in degree toward the center. 
Male. The structure described by the author of the species as a 
“cone-shaped projection directed outward and upward” from the 
lateral margin of the maxilla is a tooth which I assume to be used in 
co-operation with the chitinized ridge on the base of the palpal femur, 
a structure found in many male argiopids. The second femur has the 
proximal prolateral groove and ridge corresponding to the hook on 
the first coxa. The main features of the palp are shown in Figure 4.
