Nigma is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967. [2] They have a wide distribution, including Eurasia, North America, and Northern Africa. [1] N. walckenaeri is one of the biggest members of the Dictynidae, growing up to 5 millimetres (0.20 in) long. They are translucent green and sometimes have red or black markings on the abdomen. [3]
As of May 2019 [update] it contains fourteen species: [1]
Dictynidae is a family of cribellate, hackled band-producing spiders first described by Octavius Pickard-Cambridge in 1871. Most build irregular webs on or near the ground, creating a tangle of silken fibers among several branches or stems of one plant.
Mexitlia is a genus of North American cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967. As of May 2019 it contains only three species: M. altima, M. grandis, and M. trivittata.
Altella is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Eugène Simon in 1884.
Chorizomma is a monotypic genus of European dwarf sheet spiders containing the single species, Chorizomma subterraneum. It was first described by Eugène Simon in 1872, and has only been found in Spain and France. Originally placed with the funnel weavers, it was moved to the Dictynidae in 1967, and to the Hahniidae in 2017.
Dictyna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Carl Jakob Sundevall in 1833.
Scotophaeus is a genus of ground spiders that was first described by Eugène Simon in 1893.
Argenna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Tamerlan Thorell in 1870.
Banaidja is a monotypic genus of South Pacific cribellate araneomorph spiders in the family Dictynidae containing the single species, Banaidja bifasciata. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Samoa. The type species was transferred from Dictyna in 1929, retaining the original species name.
Blabomma is a genus of araneomorph spiders in the family Cybaeidae, and was first described by R. V. Chamberlin & Wilton Ivie in 1937. Originally placed with the funnel weavers, it was moved to the Dictynidae in 1967, and to the Cybaeidae in 2017.
Callevophthalmus is a genus of Australian cribellate araneomorph spiders in the family Dictynidae, and was first described by Eugène Simon in 1906. As of May 2019 it contains only two species: C. albus and C. maculatus. Originally placed in the Amaurobiidae, it was moved to the Dictynidae in 1967.
Devade is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Eugène Simon in 1884. Originally placed with the Amaurobiidae, it was moved to the intertidal spiders in 1983, then to the Dictynidae in 1989.
Iviella is a genus of North American cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967. As of May 2019 it contains only three species: I. newfoundlandensis, I. ohioensis, and I. reclusa.
Lathys is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Eugène Simon in 1884. It is a replacement name for "Lethia" Menge, 1869 because that name was already in use as a synonym for a genus of moths.
Marilynia is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967. As of May 2019 it contains only two species: M. bicolor and M. bicolor.
Mizaga is a genus of West African cribellate araneomorph spiders in the family Dictynidae, and was first described by Eugène Simon in 1898. As of May 2019 it contains only two species, both found in Senegal: M. chevreuxi and M. racovitzai. Originally placed with the funnel weavers, it was moved to Dictynidae in 1967.
Sudesna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Pekka T. Lehtinen in 1967.
Tahuantina is a monotypic genus of South American cribellate araneomorph spiders in the family Dictynidae containing the single species, Tahuantina zapfeae. It was first described by Pekka T. Lehtinen in 1967, and has only been found in Chile.
Brigittea is a genus of araneomorph spiders in the family Dictynidae, first described by Pekka T. Lehtinen in 1967.
Shango capicola is a species of African cribellate araneomorph spiders in the family Dictynidae. It is the only species in the monotypic genus Shango. The genus was first described by Pekka T. Lehtinen in 1967, and has only been found in South Africa.
