Araneus singiformis , — Bonnet, 1955, Bibliographia Araneorum, vol. 2, p. 
600. 
Note. Figure 69 was prepared from the holotype of S. orotes , 
a specimen that was parasitized by a nematomorph worm. 
Description. Female from South Dakota. Total length 3.8 mm. 
Carapace 1.5 mm long, 1.2 mm wide. First femur, 1.2 mm; patella 
and tibia, 1.4 mm; metatarsus, 0.9 mm; tarsus, 0.4 mm. Second 
patella and tibia, 1.2 mm; third, 0.9 mm; fourth, 1.3 mm. 
Male from South Dakota. The first tibia is swollen at the proxi- 
mal end (Fig. 71). Total length 2.7 mm. Carapace 1.3 mm long, 
1.3 mm wide. First femur, 1.2 mm; patella and tibia, 1.6 mm; 
metatarsus, 0.9 mm; tarsus, 0.5 mm. Second patella and tibia, 1.4 
mm; third, 0.9 mm; fourth, 1.3 mm. 
Variation. The total length of females is 2 . 9 - 5 .O mm, the carapace 
width, 1. 0-1.6 mm. The males are 2.4-3. 5 mm total length, cara- 
pace 1. 1 -1. 4 mm wide. 
Diagnosis. Females can be distinguished by the concave margin 
on each side of the median septum of the epigynum, and the wide 
anteriorly curved posterior margin on each side (Fig. 61), while the 
septum of II. rubens is more or less triangular. The embolus of the 
palpus is short (Figs. 67, 70) and the terminal apophysis above the 
embolus at a right angle to its long axis (Figs. 67, 70), separating 
the species from H. rubens , which has a long embolus. 
Natural History. The species has been collected by beating pines 
in Alberta, sweeping meadow in South Dakota, from meadow and 
litter in woods in Arkansas, a grassy field in California, in old weedy 
overgrown ranch at Yuma, Arizona, a strawberry field in Arkansas, 
and grass in Louisiana. Males are mature in June and July, females 
from May to August, and February in Florida. 
Distribution. From Hondo, Alberta, northern New England to 
Santa Catalina Island, California, San Antonio, Texas and 2.5 miles 
southwest of Archer, Florida (Map 3).
