A spinneret is a silk-spinning organ of a spider or the larva of an insect. Some adult insects also have spinnerets, such as those borne on the forelegs of Embioptera. Spinnerets are usually on the underside of a spider's opisthosoma, and are typically segmented. While most spiders have six spinnerets, some have two, four, or eight. They can move both independently and in concert.
Scaffold web spiders (Nesticidae) is a family of araneomorph spiders closely allied with tangle web spiders. Like the "Theridiidae", these spiders have a comb of serrated bristles on the hind tarsi that are used to pull silk bands from the spinnerets. It contains 16 genera and about 300 species, many of which are associated with caves or overhangs. The genus Nesticus is the type for the family and is found throughout the world. The related Eidmannella has speciated considerably in Texas caves and includes some extremely localized species that are considered threatened. One species, Eidmannella pallida, is found in caves and under overhangs, but also in agricultural fields and other habitats away from such restricted areas. The genus Carpathonesticus is found in central Eurasia.
Nesticella mogera is a spider from the family Nesticidae. It is the type species of the genus Nesticella.
Schenkeliella is a monotypic genus of Sri Lankan long-jawed orb-weavers containing the single species, Schenkeliella spinosa. The species was first described by Octavius Pickard-Cambridge in 1871 under the name Oeta spinosa, but it was renamed to "Schenkeliella" by Embrik Strand in 1934 because the name was already in use for a genus of ermine moths. Originally placed with the Nesticidae, it transferred to the Tetragnathidae in 1980.
Aituaria is a genus of spiders in the family Nesticidae. It was first described in 1998 by Esyunin & Efimik. As of 2016, it contains two species, Aituaria nataliae and Aituaria pontica, the latter of which was transferred from Nesticus first to Carpathonesticus, then to Aituaria.
Canarionesticus is a monotypic genus of spiders in the family Nesticidae. It was first described in 1992 by Wunderlich. Its sole species is Canarionesticus quadridentatus, found in the Canary Islands.
