Theridion agrifoliae
Theridion agrifoliae is a species of cobweb spider in the family Theridiidae, described by Levi in 1957. It is native to western North America, with records from the United States and Canada. Like other members of Theridiidae, it constructs irregular, three-dimensional webs to capture prey. The species epithet "agrifoliae" suggests an association with coast live oak (Quercus agrifolia), though specific ecological relationships remain poorly documented.
Theridion goodnightorum
Theridion goodnightorum is a species of cobweb spider in the family Theridiidae, described by arachnologist Herbert W. Levi in 1957. The species epithet honors the husband-and-wife arachnologists Clarence and Marie Goodnight. Like other members of the genus Theridion, this species constructs irregular, three-dimensional cobwebs and possesses the characteristic comb-like bristles (setae) on the hind tarsi used to manipulate silk. The species is documented from the southwestern United States and Mexico.
Theridion kawea

The species has been documented in the southwestern United States and Mexico.
Theridion neshamini
Theridion neshamini is a species of cobweb spider in the family Theridiidae, described by Levi in 1957.

As a member of Theridiidae, it is presumed to construct irregular, three-dimensional cobwebs for prey capture.
