Tissahamia Ethagala
''Tissahamia ethagala'' is a species of spider in the family Pholcidae. It is endemic to Sri Lanka. Taxonomy The species was first described in 2011 by Huber as ''Pholcus ethagala''. It was transferred to the new genus ''Tissahamia'' in 2018 as a result of a molecular phylogenetic study.

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 ...

Pholcidae
The Pholcidae are a family of araneomorph spiders. The family contains over 1,800 individual species of pholcids, including those commonly known as cellar spider, daddy long-legs spider, carpenter spider, daddy long-legger, vibrating spider, gyrating spider, long daddy, and skull spider. The family, first described by Carl Ludwig Koch in 1850, is divided into 94 genera. The common name "daddy long-legs" is used for several species, especially ''Pholcus phalangioides'', but is also the common name for several other arthropod groups, including harvestmen and crane flies. Appearance Pholcids are thin and delicate arachnids. The body, resembling the shape of a peanut, is approximately 2–10 mm (0.08–0.39 inch) in length, and the legs may be up to 50 mm (1.97 inches) long. ''Pholcus'' and ''Smeringopus'' have cylindrical abdomens and eyes arranged in two lateral groups of three and two smaller median contiguous eyes. Arrangements of eight and six ey ...

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 ...

Tissahamia
''Tissahamia'' is a genus of southeast Asian Pholcidae, cellar spiders named after Vedda, Wanniyalaeto chief Uru Warige Tissahami. It was erected in 20180 for several species transferred from ''Pholcus'' after a Molecular phylogenetics, molecular phylogenetic study of the Calapnita-Panjange clade of Pholcidae. They have long, thin opisthosoma, abdomens that bend upward near the end. They also have six eyes, three on each of two eye stalks. Species it contains twelve species: *''Tissahamia barisan, T. barisan'' (Huber, 2016) – Indonesia (Sumatra) *''Tissahamia bukittimah, T. bukittimah'' (Huber, 2016) – Singapore *''Tissahamia ethagala, T. ethagala'' (Huber, 2011) (Type_species, type) – Sri Lanka *''Tissahamia gombak, T. gombak'' (Huber, 2011) – Malaysia *''Tissahamia karuna, T. karuna'' Huber, 2019 – Sri Lanka *''Tissahamia kottawagamaensis, T. kottawagamaensis'' (Yao & Li, 2016) – Sri Lanka *''Tissahamia ledang, T. ledang'' (Huber, 2011) – Malaysia *''Tissahamia m ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

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] |
