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 ...

Utivarachna
''Utivarachna'' is a genus of Asian araneomorph spiders in the family Trachelidae first described by Kyukichi Kishida in 1940. It was largely ignored until Christa L. Deeleman-Reinhold revised the sac and ground spiders in 2001, transferring some species from ''Trachelas'' and adding several new ones. The genus was further expanded in 2014 and 2015. Species it contains seventeen species in southeast Asia: *''Utivarachna accentuata'' ( Simon, 1896) – Sri Lanka *'' Utivarachna arcuata'' Zhao & Peng, 2014 – China *'' Utivarachna bucculenta'' Deeleman-Reinhold, 2001 – Thailand *'' Utivarachna chamaeleon'' Deeleman-Reinhold, 2001 – Borneo *'' Utivarachna dusun'' Deeleman-Reinhold, 2001 – Borneo *'' Utivarachna fabaria'' Zhao & Peng, 2014 – China *''Utivarachna fronto'' (Simon, 1906) – India *'' Utivarachna fukasawana'' Kishida, 1940 (type) – Borneo *'' Utivarachna gongshanensis'' Zhao & Peng, 2014 – China *''Utivarachna gui'' (Zhu, Song & Kim, 1998) – China *''U ...

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, the Burghers ...

Trachelidae
Trachelidae is a family of araneomorph spiders (more recently evolved spiders with inward-pointing chelicerae) first described by Eugène Simon in 1897 as a subfamily called "Tracheleae" ("Trachelinae" in modern terminology). The Trachelidae family, also known as "ground sac spiders", is within the group of spiders known as the RTA clade, which includes mostly wandering spiders that do not use webs. Spiders in the Trachelidae family are characterized as being 3-10mm long and having a red cephalothorax and a yellow/tan abdomen. They are commonly found indoors. It was placed in the family Clubionidae, then later in Corinnidae when the Clubionidae were split up. The first study that suggested Trachelidae should be considered its own family was done by Deeleman-reinhold in 2001 as part of an analysis of RTA Clade spiders. An analysis by Martín J. Ramírez in 2014 suggested that it was not closely related to other members of the Corinnidae, and was better treated as a separate family ...

Endemic Fauna Of Sri Lanka
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
