Tivyna
Tivyna is a genus of cribellate araneomorph spiders in the family Dictynidae, established by R. V. Chamberlin in 1948. The genus contains four species, all but one restricted to the United States. One species, T. spatula, has a broader Caribbean distribution including Mexico, Cuba, and the Bahamas. These spiders are characterized by the presence of a cribellum, a silk-producing organ used to create woolly, non-sticky capture silk.
