and one-half to two diameters from laterals. Posterior median eyes 
one and one-quarter diameters apart, two diameters from laterals. 
Laterals separated by about their radius. Chelicerae of male cornicu- 
late, with a blunt tooth. Female chelicerae smooth with a short tooth

Diagnosis. This species is very close to Steatoda andina (Keyser- 
ling) but differs in having the embolus shorter with a spur, in having 
a smaller conductor, and having a median apophysis of different shape 
(Fig. 22). The female epigynum differs in having a scape in a shallow 
depression. The depression is not bordered. The posterior edge of the
