Epeirotypus Chavarria
''Epeirotypus'' is a genus of ray spiders that was first described by Octavius Pickard-Cambridge in 1894. Description Adult ''Epeirotypus'' species have a body length of 1–3 mm. The carapace ranges in colour from light yellow to almost black, and the head region is not elevated. The sternum is smooth, convex, and rounded to the rear. The abdomen is ovoid, usually with a dorsal pattern which varies by species and sometimes bearing posterior lateral tubercules. The legs are short and stout, light tan or sometimes dark with annulations. The femoral length is – the total width of the carapace, and the tarsi bear an irregular group of serrated hairs on the ventral side. They have eight eyes, all approximately equal in size. The AME are separated by half their diameter and the PME typically separated by their diameter. Species it contains three species, found in China, Costa Rica, and Mexico: '' E. brevipes'', '' E. chavarria'', and '' E. dalong''. See also * List of Th ...

Octavius Pickard-Cambridge
Octavius Pickard-Cambridge Fellow of the Royal Society, FRS (3 November 1828 – 9 March 1917) was an England, English clergyman and zoologist. He was a keen arachnologist who described and named more than 900 species of spider. Life and work Pickard-Cambridge was born in Bloxworth rectory, Dorset, the fifth son of Rev. George Pickard, rector and squire of Bloxworth: the family changed its name to Pickard-Cambridge in 1848 after receiving the property left behind by a relative, Charles Owen Cambridge, of Whitminster House in Gloucestershire. Octavius was tutored at home by the poet William Barnes, after failing to receive admission to Winchester College. He also learned to play the violin from Sidney Smith. He then studied law in London before theology at the Durham University, University of Durham. He was very active and made many friends in this period. He served as steward at steeplechases and presided over the college choral society. In 1857 he presented the Pickard-Camb ...

Spiders Of Mexico
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...

Araneomorphae Genera
The Araneomorphae (also called the Labidognatha) are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae (tarantulas and their close kin), where they point straight down. Araneomorphs comprise the vast majority of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations they can employ during prey capture. They have fewer book lungs (when present), and the females typically live one year. The Mygalomorphae have fangs that face towards the ground, and which are parallel to the long axis of the spider's body, thus they have only one orientation they can employ during prey capture. They have four pairs of book lungs, and the females often live many years. Image:Atrax robustus.jpg, This ''Atrax robustus'' shows the orientation of Myglamorphae fangs. Image:Che ...

Theridiosomatidae
The ray spiders (Theridiosomatidae) are a family of spiders first described by Eugène Simon in 1881. They are most recognizable for their construction of cone-shaped webs. The family contains several genera which actively hunt for prey by using their webs to slingshot themselves towards prey. Genera , the World Spider Catalog accepts the following genera: *'' Andasta'' Simon, 1895 – Seychelles, Malaysia, Sri Lanka *'' Baalzebub'' Coddington, 1986 – Central America, Brazil, Australia, China *'' Chthonopes'' Wunderlich, 2011 – Laos *'' Chthonos'' Coddington, 1986 – Ecuador, Brazil, Peru *'' Coddingtonia'' Miller, Griswold & Yin, 2009 – Malaysia, Laos *'' Cuacuba'' Prete, Cizauskas & Brescovit, 2018 *'' Epeirotypus'' O.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...
