Udubidae
Udubidae is a family of araneomorph spiders, most of whose members were formerly placed in the family Zorocratidae, which is no longer accepted. Phylogeny A study investigating the phylogenetic relationships of lycosoid spiders concluded that the genera formerly placed in the family Zorocratidae fell into two groups. The largest group formed the sister clade to the "grate-shaped tapetum clade" (see the cladogram below). The type genus, '' Zorocrates'', grouped with '' Zoropsis'' inside the grate-shaped tapetum clade. Some earlier studies had also cast doubt on the monophyly of the Zorocratidae. A 2003 study found that ''Raecius'', ''Uduba'', and ''Zorodictyna'' formed a clade somewhat separated from ''Zorocrates''. A 2014 study including ''Zorocrates'' and ''Raecius'' did not find that they grouped together., p. 289 Moving the type genus to a different family meant that a new family name was needed for the remaining members. Griswold and Polotow proposed "Udubidae", with the type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zorodictyna
''Zorodictyna'' is a genus of spiders in the family Udubidae native to Madagascar. It has been described as an intermediate genus between Zoropsidae and Dictynidae, though it is now placed in Udubidae. This genus was originally placed in the family Zoropsidae, but it has been reassigned several times since. In 1967, Lehtinen moved it to Miturgidae. In 1999, it was moved back to Zoropsidae, and in 2015, it was moved to Udubidae. Species , the genus has two accepted species. * '' Zorodictyna inhonesta'' – Madagascar Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa ... * '' Zorodictyna oswaldi'' – Madagascar References {{Taxonbar, from=Q2189826 Spiders of Madagascar Udubidae Taxa named by Embrik Strand Araneomorphae genera ...

Lycosoidea
Lycosoidea is a clade or superfamily of araneomorph spiders. The traditional circumscription was based on a feature of the eyes. The tapetum is a reflective layer at the back of the eye, thought to increase sensitivity in low light levels. Lycosoids were then defined by having a "grate-shaped" tapetum. Research from the late 1990s onwards suggests that this feature has evolved more than once, possibly as many as five times, so that the original Lycosoidea is paraphyletic. Studies published in 2014 and 2015 suggest that a smaller group of families does form a clade. The reflective attributes of the tapeta vary significantly betwixt lycosoid spiders. Phylogeny The phylogeny of the Lycosoidea and related groups has been studied using both morphological and molecular data. Comparing these studies is complicated by the redrawing of family boundaries. Thus potential lycosoid genera placed in the family Miturgidae in 1993, such as '' Uliodon'', have since been placed in the Zoropsi ...

RTA Clade
The RTA clade is a clade of araneomorph spiders, united by the possession of a retrolateral tibial apophysis – a backward-facing projection on the tibia of the male pedipalp. The clade contains over 21,000 species, almost half the current total of about 46,000 known species of spider. Most of the members of the clade are wanderers and do not build webs. Despite making up approximately half of all modern spider diversity, there are no unambiguous records of the group from the Mesozoic and molecular clock evidence suggests that the group began to diversify during the Late Cretaceous. Families In 2005, Coddington included 39 families in a cladogram showing the RTA clade: * Agelenidae *Amaurobiidae *Ammoxenidae *Amphinectidae ( paraphyletic; merged into Desidae) *Anyphaenidae * Cithaeronidae *Clubionidae *Corinnidae *Cryptothelidae *Ctenidae * Desidae *Dictynidae *Gallieniellidae *Gnaphosidae * Lamponidae * Liocranidae *Lycosidae * Miturgidae (paraphyletic) * Oxyopidae *Philodromi ...

Araneomorphae
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:C ...

Sri Lanka
Sri Lanka (, ; si, ශ්රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with India and Maldives. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its largest city and financial centre. Sri Lanka has a population of around 22 million (2020) and is a multinational state, home to diverse cultures, languages, and ethnicities. The Sinhalese are the majority of the nation's population. The Tamils, who are a large minority group, have also played an influential role in the island's history. Other long established groups include the Moors, ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...
