Flexicrurum
''Flexicrurum'' is a genus of spiders from China similar to the genera '' Althepus'' and '' Leclercera''. Tong and Li originally placed the genus in ''Ochyroceratidae'', but Tong later moved it to ''Psilodercidae''. Males are generally smaller than 2 mm, but the size of females is unknown. The name is derived from Latin ''flex'' "curved", and ''crur'' "leg", referring to the inner turned palpal tibia of the male. three described species have been found in caves of Hainan Island Hainan (, ; ) is the smallest and southernmost province of the People's Republic of China (PRC), consisting of various islands in the South China Sea. , the largest and most populous island in China,The island of Taiwan, which is slightly ....

Psilodercidae
''Psilodercidae'' is a family of spiders first described as a subfamily of Ochyroceratidae by Machado in 1951 and raised to family rank by J. Wunderlich in 2008. These spiders can be distinguished by the "segestriid positioning" of their six eyes, the absence of leg bristles, strong Wiktionary:apex, apical bristles on the Palpal bulb#Structure, cymbium, and several pairs of spermathecae in females. Genera , the World Spider Catalog accepts the following genera, but it is relatively unstudied and may change as more information becomes available. In particular, Wunderlick remarked that ''Psiloderces'' is too broad and should be split into smaller, more distinct groups. *''Althepus (spider), Althepus'' Thorell, 1898 — Asia *''Flexicrurum'' Tong & Li, 2007 — China *''Leclercera'' Deeleman-Reinhold, 1995 — Asia *''Luzonacera'' F.

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 ...

Spider
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 ...

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 ...

Althepus (spider)
''Althepus'' is a genus of spiders in the family Psilodercidae. It was first described in 1898 by Tamerlan Thorell Tord Tamerlan Teodor Thorell (3 May 1830 – 22 December 1901) was a Swedish arachnologist. Thorell studied spiders with Giacomo Doria at the Museo Civico di Storia Naturale de Genoa. He corresponded with other arachnologists, such as Octaviu .... , it contains 60 species, all from Asia.

Leclercera
''Leclercera'' is a genus of spiders in the family Psilodercidae found in Asia, including Thailand, Nepal, China and the Philippines. It was first described in 1995 by Christa L. Deeleman-Reinhold, who named it after a fellow collector of Asian spiders. She originally placed under ''Ochyroceratidae'', but it was later moved it to ''Psilodercidae''. It is named for Philippe Leclerc, a collector of spiders in southeast Asia. Members of this genus are usually larger than those in ''Psiloderces'' and ''Merizocera'', but can also be distinguished by teeth on the retromargin of the chelicerae (behind the fang), a round maxillae, and a longer labium. They can be distinguished from '' Althepus'' by the rounded posterior margin of the carapace and a shallow fovea Fovea () (Latin for "pit"; plural foveae ) is a term in anatomy. It refers to a pit or depression in a structure. Human anatomy *Fovea centralis of the retina * Fovea buccalis or Dimple * Fovea of the femoral head * Troc ...

Ochyroceratidae
Ochyroceratidae is a six-eyed spider family, with 165 described species in ten genera. They are common inhabitants of caves and the tropical forest litter of South Africa, the Caribbean, Asia and South America. Considered an ecological counterpart of the Linyphiidae of the northern temperate zone, species are especially diverse in the Indo-Pacific region. These spiders build small, irregular sheet-webs in dark, damp places and typically carry eggs in their chelicerae until they hatch. Body length can range from , and some species with very long legs (''Althepus'', ''Leclercera'') are superficially similar to members of Pholcidae. Differences between males and females are still relatively unknown, but at least one species in the genus ''Theotima'' (''T. minutissima'') was shown to be parthenogenetic. Genera , the World Spider Catalog accepts the following genera: *'' Dundocera'' Machado, 1951 — Angola *'' Euso'' Saaristo, 2001 — Seychelles *'' Fageicera'' Dumitrescu & George ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Pedipalp
Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs. Overview Pedipalps are composed of six segments or articles: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus. In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs. The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons ( pincers) of great size, as in scorpions. The pedipalps of Solifugae are covered in setae, but have not been studied in detail. Comparative studies of pedipalpal morphology may suggest that leg-like pedipalps are primitive in arachnids.
