Neriene
Neriene is a genus of sheet-web weaving spiders (family Linyphiidae) first described by John Blackwall in 1833. As of 2025, the genus contains approximately 62 species distributed across Africa, Asia, Europe, North America, and Greenland. These spiders construct distinctive sheet webs—horizontal platforms of silk often accompanied by a dome or bowl-shaped structure above. Species in this genus are small-bodied, with mature females typically measuring only a few millimeters. The genus has been subject to behavioral research, particularly regarding mating plug function in species such as N. emphana.
