Holotype. Female from Rustler Camp, Chiricahua Mts., Cochise 
Co., Arizona, 9 Sept. 1950 (W. J. Gertsch) in the American 
Museum of Natural History. The name abigeatus is a Latin verb 
for cattle stealing, rustling. 
Description. Female. Carapace dark brown, marbled on lighter 
brown with some light setae. Sternum dark brown, coxae light. Legs 
banded brown on yellow-white with some white-tipped setae. Dor- 
sum of abdomen with a median longitudinal line of white spots and 
four pairs of dark brown chevrons, the posterior pair fused in mid- 
dle on dark brown speckled background (1971, fig. 236). Venter 
with a black band from epigynum to spinnerets, and a pair of white 
spots side by side. Spinnerets dark brown. Eyes subequal in size. 
Anterior median eyes slightly more than their diameter apart. The 
abdomen has a pair of anterior dorsal humps. Total length 11.0 mm. 
Carapace 3.7 mm long, 3.5 wide. First femur, 4.5 mm; patella and 
tibia, 5.5; metatarsus, 3.7; tarsus, 1.4. Second patella and tibia, 
5.0 mm; third, 2.9; fourth, 4.9. 
Male. Coloration similar to that of female, except carapace more 
uniform light brown. Thorax with a longitudinal groove. Eye size 
and spacing as in female. First coxa with a hook, second femur with 
groove. Second coxa with a small posterior, proximal tubercle, no 
spur. Second tibia swollen with macrosetae on venter. Total length 
7.0 mm. Carapace 3.8 mm long, 3.2 wide First femur, 5.0 mm; 
patella and tibia, 6.5; metatarsus, 3.6; tarsus, 1.3. Second patella 
and tibia, 5.0 mm; third, 2.9; fourth, 4.5. 
Diagnosis. The constricted neck of the scape of the epigynum 
covering a large hollow space (Figs. 6, 8) separates this species from 
Araneus illaudatus. The internal genitalia (Figs. 5, 7) are heavily 
sclerotized and were cleared but not macerated as only few speci- 
mens were available. 
The male will key out to A. washingtoni in Levi (1971) but the 
palpus is similar to that of A. nordmanni. The palpus has a terminal 
apophysis prong similar to that of A. nordmanni but differs by the 
shape of the shorter embolus (Fig. 11) and shape of conductor 
(Figs. 9, 10).
