Spiders of the ecribellate haplogyne family Caponiidae are unusual in that most species have only two eyes, which is unheard of in other spiders. 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.

Description

These spiders of about 2 to 5mm are rarely noticed, but generally look like somewhat faded woodlouse hunter spiders in the genus Dysdera. The family Dysderidae ( woodlouse hunters, sowbug-eating spiders or cell spiders) are araneomorph Spiders found primarily in Dysdera is a genus of spiders from the family Dysderidae, with more than 200 species The carapace (cephalothorax or prosoma) is orange and the abdomen (opisthosoma) light gray. A carapace is a dorsal section of an Exoskeleton or shell in a number of animal groups In Vertebrates such as Mammals the abdomen (belly constitutes the part of the body between the Thorax (chest and Pelvis. The two-eyed species have their two eyes in the anterior middle of the carapace.

Eye numbers

Habits

Their habits are for the most part unknown. At least some species are known to hunt other spiders.

Relationships

The fact that they are ecribellate and haplogyne indicates that they are probably relatively primitive. A cribellum is a kind of comb-like device in certain Spiders used to separate fibers of Silk drawn from its Spinnerets into many extremely fine fibers giving The Haplogynae are a series of araneomorph spiders Unlike the Entelegynae, they lack hardened (sclerotized female genitalia ( Epigynes Primitive is a descriptive term often used in the field of Evolution to describe particular Species or traits that are characteristic of an older evolutionary Calponia harrisonfordi from California seems to be the most primitive member of the family. Calponia harrisonfordi is a species of Spider discovered in 1993 by the arachnologist Norman I California ( is a US state on the West Coast of the United States, along the Pacific Ocean. Their phylogenetic relationships have long been enigmatic, but in the early 1990s it was determined that they are probably a sister group of the Tetrablemmidae plus the four families inside the Dysderoidea superfamily. The Tetrablemmidae are a spider family with 126 described species in 29 genera that occur throughout the world tropics The Dysderoidea are a Superfamily of araneomorph spiders They contain four families of six-eyed spiders Dysderidae

The subfamily Nopinae consists at least of the genera Nops, Nopsides, Orthonops and Tarsonops. The remaining genera are unlikely to form a monophyletic group. A clade is a taxonomic group comprising a single Common ancestor and all the descendants of that ancestor

Distribution

The family can be found in Africa and America from Argentina to the USA. The Americas are the lands of the Western hemisphere or New World, consisting of the Continents of North America and South America For a topic outline on this subject see List of basic Argentina topics. The United States of America —commonly referred to as the

Names

Calponia is a contraction of Californian Caponia, because the single species Calponia harrisonfordi has, like the African genus Caponia eight eyes. The species name is in honor of Harrison Ford, recognizing his efforts on behalf of the American Museum. Harrison Ford (born July 13, 1942) is an Academy Award - and BAFTA -nominated as well as Golden Globe -winning American The American Museum in Britain is based at Claverton Manor, near Bath in a house designed by Jeffry Wyatville and built in the 1820s on the site of a

The Chilean caponiid fauna differs from that of the rest of the Neotropics in lacking members of the Nopinae (named after the genus Nops). Three genera newly described by Norman I. Platnick in 1994 were thus named Notnops, Taintnops and Tisentnops, emphasizing this fact. Norman I Platnick is an American Arachnologist, and the Peter J The only Taintnops species, T. goloboffi, is named in honor of one of the collectors, P. A. Goloboff.
