The Spiders of Europe and Greenland
Family: Nesticidae (Comb-footed Cellar Spiders)
Biology: The common name for the family is comb-footed cellar spiders or scaffold web spiders. Most European species are found in south and southeast Europe, and only three species of Nesticus reach central Europe. One of these (Nesticus cellulanus) reaches as far North as Scandinavia. Eidmannella pallida is of North American origin, but has now become a cosmopolitan species, introduced to much of the world, however not northern Europe. The species of the family make irregular wide meshed cobwebs.
Characters of family: The spiders of the family Nesticidae are closely related to the Theridiidae (comb-footed spiders). Most specimens of both families have a comb of 6-10 serrated bristles on tarsus IV that are used to pull silk from the spinnerets. The Nesticids differ from the Theridiids by having a thickened edge on the anterior rim of the lower lip (rebordered labium), and by having longer legs, particularly the first pair. The legs are densely clothed with fairly long bristles, longer than in any theridiid. Leg spines are few, and differ only scarcely from the leg bristles. The eight eyes of the Nesticids are arranged in two rows of four.
