The Spiders of Europe and Greenland
Family: Oonopidae (Dwarf Cell Spiders)
Biology: Some species occurring in North and Central Europe are introduced to greenhouses and other buildings from warmer regions.
Characters of family: The members of this family are rather small, about 2 mm in body length. They have only six, relatively large eyes that are virtually contigous and situated on a narrow head, marginally wider than the eyegroup. The species are generally coloured in shades of red, pink and orange.
This family is represented in Europe with 32 species in 12 genera (van Helsdingen, 2009; Platnick, 2009). European genera (number of species in parenthesis): Diblemma (1), Gamasomorpha (1), Heteroonops (1), Ischnothyreus (2), Oonopinus (2), Oonops (10), Opopaea (3), Orchestina (8), Pelicinus (1), Silhouettella (1), Tapinesthis (1), Triaeris (1).
Genus: Oonops Templeton, 1835
Characters of genus: The number of paired spines on Tibia I separates the species with O. domesticus having five pairs and O. pulcher having just four.
There are 10 European species (van Helsdingen, 2009; Platnick, 2009): Oonops amoenus, O. domesticus, O. lubricus, O. mahnerti, O. placidus, O. placidus corsicus, O. procerus, O. pulcher, O. pulcher hispanicus, O. tubulatus.
Oonops domesticus Dalmas, 1916
Description: Oonops domesticus is easily recognised by its red colour and way of walking, which alternates between slow walks and short runs. This is particularly evident if the spider is gently disturbed. The species is one of only about five Danish spiders with six eyes, the remaining more than 500 species having eight. The eyes of Oonops domesticus are pearly indicating this is a nocturnal species. Size: Female 2 mm; male 1.5 mm. Maturity: All year. Habitat: The species lives exclusively within houses and rare outdoor findings are supposedly stray specimens. Range: Belgium, Denmark, France (Mainland), Germany, Great Britain (Mainland), Ireland, Italy (Mainland), Netherlands, Poland, Portugal (Azores), Portugal (Mainland), Slovakia, Switzerland, Ukraine (van Helsdingen 2009.1). Global range: Western Europe to Russia (Platnick 10.0).
