The tube-dwelling spiders (family Segestriidae) consist of two large and widespread genera (Segestria and Ariadna) and one monotypic genus (Gippsicola from Australia). Segestria florentina is the biggest segestriid Spider of Europe. Arthropods are Animals belonging to the Phylum Arthropoda (from Greek ἄρθρον arthron, " Joint " Arachnids are a class ( Arachnida) of joint-legged Invertebrate Animals in the subphylum Chelicerata. Spiders are Predatory Invertebrate Animals that have two body segments, eight legs no chewing mouth parts and no wings The Dysderoidea are a Superfamily of araneomorph spiders They contain four families of six-eyed spiders Dysderidae Eugène Simon ( April 30, 1848 - November 17, 1924) was a French Arachnologist. This page lists all described species of the spider family Segestriidae as of June 19 2007 Segestria is a genus of segestriid spiders that occur mainly in Eurasia. Monotypic is an adjective that refers to a taxonomic group with only one type: In Botany, "monotypic" means that a Taxon has only A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic For a topic outline on this subject see List of basic Australia topics. The family is easily recognized because its members have six eyes (most spiders have eight) arranged in a semicircle and have the first three pairs of legs arranged forward (most spiders have only the first two pairs so arranged. Spiders are Predatory Invertebrate Animals that have two body segments, eight legs no chewing mouth parts and no wings ) The leg structure appears to be an adaptation for living in silken tubes, which unlike those of the atypical tarantulas, may branch and are often built in tree bark fissures, as well as under stones. The atypical tarantulas or purseweb spiders (family Atypidae) consist of only three genera. A tree is a perennial Woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or These are haplogyne primitive araneomorphs related to the Dysderidae. The Haplogynae are a series of araneomorph spiders Unlike the Entelegynae, they lack hardened (sclerotized female genitalia ( Epigynes The Araneomorphae are a Suborder of Spiders They are distinguished by having Chelicerae (fangs that point diagonally forward and cross in a pinching action The family Dysderidae ( woodlouse hunters, sowbug-eating spiders or cell spiders) are araneomorph Spiders found primarily in Both Segestria and Ariadna are known from North America, South America, Eurasia, Africa and New Zealand, while Ariadna is also known from Australia. South America is a Continent of the Americas, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a For the superstate in George Orwell 's novel see Nations of Nineteen Eighty-Four. New Zealand is an Island country in the south-western Pacific Ocean comprising two main landmasses (the North Island and the South Island This wide distribution attests to the ancient origin of this family.
