Figures 3, 4 
Aranea illaudata Gertsch and Mulaik, 1936, Amer. Mus. Novitates, no. 
863, p. 19, figs. 36, 37, $. Male holotype from Edinburg, Texas in the 
American Museum of Natural History, examined. 
Araneus pima Levi, 1971, Bull. Mus. Comp. Zool., vol. 141, p. 176, plates 
1, 4, figs. 218-232, 9, $, map 8. Female holotype from Madera Canyon, 
Santa Rita Mountains, Pima Co., Arizona in the American Museum of 
Natural History. NEW SYNONYMY. 
Araneus illaudatus, — Levi, 1971, Bull. Mus. Comp. Zool., vol. 141, p. 176, 
figs. 238-240, $ (not figs. 233-237, $ which is A. abigeatus, n. sp.). 
Note. Some A. illaudatus males had shorter embolus caps than 
others. The distribution maps (Levi, 1971) of A. illaudatus and 
A. pima should be combined. 
Diagnosis. Males of the three similar species can be separated by 
the length of the terminal 'apophysis in apical view. Araneus gem- 
moides Chamberlin and Ivie has the shortest, widest terminal apophy- 
sis (Fig. 1) and largest palpal tibia (1971, figs. 1 99-200). Araneus 
gemma (McCook) has a pointed, curved terminal apophysis, widest 
at the base (Fig. 2). Araneus illaudatus has a long curved terminal 
apophysis, the sides more or less parallel (Figs. 3, 4). 
Size ranges. Total length of females varied 11.5 to 27 mm. The 
smallest female was hand-raised from Chihuahua Mts., Arizona 
and another collected at Gateway, Oregon, both 11.5 mm. Total 
length of California females in mm: 14, 17, 22; Utah: 13, 23; 
Arizona, Fort Grant: 22; Huachuca Mts.: 18, 18, 18, 20, 23; 
Chihuahua Mts.: 13, 19, 21, 22, 23; Santa Rita Mts.: 18, 20, 24; 
Grand Canyon: 15; Texas: 14, 18; Mexico, Chihuahua: 18. Not 
all females were measured, only one from each collection. There 
appears to be no geographic pattern. 
Total length of males 2.9 to 7.9 mm. Measurements of males in 
mm: Utah, Watson: total length 4.2, carapace 1.9 long, 1.5 wide; 
Arizona, Santa Rita Mtns. : total length 7.9, carapace 4.1 long, 
3.0 wide; Chihuahua Mts.: total length 2.9 to 3.9 mm, carapace 
1.6 to 1.9 long, 1.2 to 1.6 wide, three specimens; Texas: total length 
3.6 to 4.0 mm, carapace 1.9 to 2.0 long, 1.3 to 1.5 wide, two speci- 
mens; specimen from Chihuahua Mts. hand-raised in North Caro- 
lina: total length 6.6 mm, carapace 3.6 long, 2.8 wide (Fig. 4). 
All males were measured; the 6.6 mm and 3.8 mm males are illus- 
trated in Figures 3, 4.
