in front by a median narrow white line. Very variable, sometimes 
with a longitudinal white line or almost black. Venter with a lighter 
W-shaped mark and lighter spots on sides. Eyes subequal in size, 
anterior median eyes one diameter apart, one and one-half diameters 
from laterals. Posterior median eyes about one diameter apart, two 
diameters from laterals. Chelicera of female with a blunt, fleshy 
tooth on anterior margin, that of male enlarged as in the genus 
Enoplognatha , with a large tooth on anterior margin (Fig. 19); there 
is no tooth, however, on posterior margin. Measurements of specimens 
from Lima, Peru. Total length of female 8.3 mm. Carapace, 3.7 mm 
long, 2.9 mm wide. First femur, 4.3 mm; patella and tibia, 5.1 mm; 
metatarsus, 3.7 mm; tarsus, 1.6 mm. Second patella and tibia, 4.1 
mm; third, 3.3 mm; fourth, 5.0 mm. Total length of male, 8.6 mm. 
Carapace, 4.2 mm long, 2.7 mm wide. First femur, 4.7 mm; patella 
and tibia, 5.5 mm; metatarsus, 4.3 mm; tarsus, 1.9 mm. Second 
patella and tibia, 4.3 mm; third, 3.6 mm; fourth, 5.0 mm. 
Variation. The epigynum (fig. 17) is variable in proportion. A 
male from Chile has a shorter embolus than males examined from 
central Peru. 
Diagnosis. The more discrete posterior rim of the depression of 
the epigynum (Fig. 17) separates this species from S. grossa (1957b, 
figs. 84, 85) with which it may be confused. The palpus (Fig. 18) 
is very different from that of S. grossa. 
Natural History. Collected in stony grassland near Lake Junin, 
shrubs in dry valley in Cajamarca and in Eucalyptus forest in Ancash.
