Originally placed with the funnel weavers, it was elevated to genus and moved to the dwarf sheet spiders in 1967, then moved to the Cybaeidae in 2017. As of May 2019 it contains only two species: D. cinctipes and D. pyrenaea.

Tunagyna is a monotypic genus of sheet weavers containing the single species, Tunagyna debilis. It was first described by Ralph Vary Chamberlin & Vaine Wilton Ivie in 1933, and is found in the United States, Canada, and Russia.
Phruronellus is a genus of North American araneomorph spiders first described by R. V. Chamberlin in 1921. Originally placed with the Liocranidae, it was moved to the Corinnidae in 2002, and to the Phrurolithidae in 2014.
Phrurolithus is a genus of araneomorph spiders first described by C. L. Koch in 1839. First placed with the Liocranidae, it was moved to the Corinnidae in 2002, then to the Phrurolithidae in 2014.
Phrurotimpus is a genus of araneomorph spiders first described by R. V. Chamberlin and Wilton Ivie in 1935. The name is a compound adjective meaning "guarding the stone". Originally added to the Liocranidae, it was moved to the Corinnidae in 2002, then to the Phrurolithidae in 2014. They have red egg sacs that look like flattened discs, often found on the underside of stones.
Phonotimpus is a genus of North American araneomorph spiders in the family Phrurolithidae. It was first described by Willis J. Gertsch and Louie Irby Davis in 1940, and placed with the Liocranidae. It was transferred to Corinnidae in 2002, then to the Phrurolithidae in 2014.
