## Summary

Amaurobius similis is a species of spider in the family Amaurobiidae. It is one of at least two common spiders found in houses known as lace-webbed spiders. The specific name similis is based on its similarity to the species Amaurobius fenestralis. Both are often found near windows, hence the specific name of A. fenestralis.
