Description. Female from Northwest Territories. Total length 
3.2 mm. Carapace 1.5 mm long, 1.3 mm wide. First femur, 1.2 
mm; patella and tibia, 1.4 mm; metatarsus, 0.9 mm; tarsus, 0.5 
mm. Second patella and tibia, 1.3 mm; third, 0.9 mm; fourth, 
1.2 mm. 
Males. The dorsum of the abdomen is brown, lightly sclerotized. 
The muscle scars are sclerotized. The carapace is smooth with a 
thoracic longitudinal line. The first tibia is swollen and slightly 
bent, with strong macrosetae. Total length 3.5 mm. Carapace 1.6 
mm long, 1.4 mm wide. First femur, 1.3 mm; patella and tibia, 
1.7 mm; metatarsus, 1.0 mm; tarsus, 0.6 mm. Second patella and 
tibia, 1.6 mm; third, i.O mm; fourth, 1.4 mm. 
Diagnosis. The shape of the median epigynal septum (Fig. 90) 
is diagnostic. The sides of the narrow septum are concave and the 
posterior transverse part is not as wide as that of II. singaeformis. 
The male can be separated from other species by the toothed edge 
of the tegulum (Fig. 97). All males were collected in pitfall traps 
and have their palpi expanded, probably as a result of ethylene glycol. 
They have been illustrated as if contracted.
