Males. Males are less distinctly marked than females. The eye 
size ratios and distances are about the same as those of female. The 
first coxa has a hook, the second tibia has macrosetae but is not 
swollen. Total length 4.0 mm. Carapace 2.3 mm long, 1.9 wide. 
Second patella and tibia, 3.0 mm; third, 1.7; fourth, 2.5. 
Variation. There is little variation in size of the few specimens 
available. The dorsum is much lighter in some individuals than in 
others; and in the pale specimens, the median carapace band and the 
dark spots on the abdomen barely show. All, however, have a dark 
sternum. 
Diagnosis. This species is close to Araneus pegnia ( Walckenaer) , 
but males differ by having three prongs on the median apophysis 
(Fig. 18) rather than two and in details of the shape of other distal 
palpal structures (Figs. 18-20). Females differ from those of A. 
pegnia by having a wider scape (Fig. 13) and also a brownish black 
sternum and brownish black venter of the abdomen surrounding a 
transverse white mark (Fig. 16). Males differ from those of A. 
thaddeus , which have a similar three-pronged median apophysis, by 
the very differently shaped embolus (Fig. 20), bearing a worm- 
shaped lamella. Such an embolus lamella is present in A. pegnia 
also, but is not illustrated in Levi (1973, figs. 436, 437). 
The species keys out to 3, A. pegnia and A. thaddeus , in my key 
to females of smaller species of Araneus (Levi, 1973, p. 488) and 
to 3 A. thaddeus in my key to males of smaller species of Araneus 
(Levi, 1973, p. 489). 
Note. This is not A. montanus Archer. The holotype of A. 
montanus was re-examined and is A. thaddeus as synonymized before 
(Levi, 1973). Females of A. apache I had previously placed in 
A. pegnia. Araneus pegnia does not seem to occur in southeastern 
Arizona; it is found in California and Sonora (Levi, 1973, map 6).
