Theridiidae is a family of spiders that are commonly known as comb-footed spiders. While theridiidae is the most commonly used term to describe this family of spiders, there are several synonyms that are also used by scientists and researchers in the field of arachnology. Some of the synonyms for theridiidae include Theridiinae, Argyrodinae, and Euryopinae. These synonyms are used to classify different subfamilies within the larger family of theridiidae. By understanding these synonyms, researchers are able to categorize and study these spiders more effectively, leading to a better understanding of their behavior, habits, and ecology.
