Dolichognatha Junlitjri
''Dolichognatha junlitjri'' is a species of orb-weaver spiders found in the Philippines. The species was discovered in Molawin Creek at Mount Makiling, and was described, illustrated and named by Aimee Lynn Barrion-Dupo and Alberto T. Barrion who published their discovery in 2014. They considered that the genus ''Prolochus'', treated a synonym of '' Dolichognatha'' by sources such as the World Spider Catalog , should be revived. It would include '' Dolichognatha longiceps'' as ''Prolochus longiceps'', and ''Prolochus junlitjri''. However, a molecular phylogenetic study in 2018 did not support this, and placed the species in ''Dolichognatha'', the placement accepted by the World Spider Catalog The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy.

Orb-weaver Spider
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs. The family has a cosmopolitan distribution, including many well-known large or brightly colored garden spiders. With 3,108 species in 186 genera worldwide, the Araneidae comprise the third-largest family of spiders (behind the Salticidae and Linyphiidae). Araneid webs are constructed in a stereotypical fashion, where a framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. Orb webs are also produced by members of other spider families. The long-jawed orb weavers (Tetragnathidae) were formerly included in the Araneidae; they are closely related, being part of the superfamily Arane ...

Molawin River
The Molawin River, also referred to as the Molawin Creek, is one of the many low volume flowing rocky streams crisscrossing the campus of the University of the Philippines Los Baños and some areas of the town of Los Baños. Molawin Creek crosses the whole of the UPLB campus and essentially cuts it in half making it necessary to construct several bridges throughout the university's history to improve the campus' integrity and general accessibility. Volume of flow depends on the average rainfall of the season and develops into a raging river during typhoons or heavy rainfall. It is a minor tributary of Laguna Lake, one among many small creeks that empty into Laguna de Bay. The origins of Molawin Creek and the other creeks in Los Baños have not been pinpointed but are generally accepted to have their origins high up in Mount Makiling. The name Molawin is a local variation of the name of the Molave tree (Vitex parviflora). Conservation Water quality monitoring conducted by the Uni ...

Mount Makiling
Mount Makiling (also known as Mount Maquiling), is an inactive stratovolcano located in the provinces of Laguna and Batangas on the island of Luzon, Philippines. The mountain rises to an elevation of above mean sea level and is the highest feature of the Laguna Volcanic Field. The volcano has no recorded historic eruption but volcanism is still evident through geothermal features like mud spring and hot springs. South of the mountain is the Makiling-Banahaw Geothermal Plant. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) classifies the volcano as "Inactive". Mount Makiling is a state-owned forest reserve administered by the University of the Philippines Los Baños. Prior to its transfer to the university, the mountain was the first national park of the Philippines. Mount Makiling National Park was established on February 23, 1933, by ''Proclamation No. 552''. However, it was decommissioned as a national park on June 20, 1963, by ''Republic Act no. 3523'' w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Dolichognatha
''Dolichognatha'' is a genus of tropical and subtropical long-jawed orb-weavers that was first described by Octavius Pickard-Cambridge in 1869. Originally placed with the Archaeidae, it was transferred to the Araneidae in 1967, and to the Tetragnathidae in 1981. Species it contains thirty-two widely distributed species: *'' Dolichognatha aethiopica'' Tullgren, 1910 – East Africa *'' Dolichognatha albida'' (Simon, 1895) – Sri Lanka, Thailand *'' Dolichognatha baforti'' (Legendre, 1967) – Congo *'' Dolichognatha bannaensis'' Wang, Zhang & Peng, 2020 — China *'' Dolichognatha comorensis'' (Schmidt & Krause, 1993) – Comoros *'' Dolichognatha cygnea'' (Simon, 1893) – Venezuela *'' Dolichognatha deelemanae'' Smith, 2008 – Borneo *'' Dolichognatha ducke'' Lise, 1993 – Brazil *'' Dolichognatha erwini'' Brescovit & Cunha, 2001 – Brazil *'' Dolichognatha incanescens'' (Simon, 1895) – Sri Lanka, Indonesia (Borneo), New Guinea, Australia (Queensland) *'' Dolichognatha ...

World Spider Catalog
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of individual web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History. After Platnick's retirement in 2014, the Natural History Museum of Bern (Switzerland) took over the catalog, converting it to a relational database. , 50,151 accepted species were listed. The order Araneae Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk.

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.

Tetragnathidae
Long-jawed orb weavers or long jawed spiders (Tetragnathidae) are a family of araneomorph spiders first described by Anton Menge in 1866. They have elongated bodies, legs, and chelicerae, and build small orb webs with an open hub with few, wide-set radii and spirals with no signal line or retreat. Some species are often found in long vegetation near water. Systematics , the World Spider Catalog accepts the following extant genera: *''Alcimosphenus'' Simon, 1895 — Caribbean *'' Allende'' Álvarez-Padilla, 2007 — Chile, Argentina *'' Antillognatha'' Bryant, 1945 — Hispaniola *'' Atelidea'' Simon, 1895 — Sri Lanka *'' Azilia'' Keyserling, 1881 — United States, Panama, South America, Caribbean *''Chrysometa'' Simon, 1894 — South America, Central America, Mexico, Caribbean *''Cyrtognatha'' Keyserling, 1881 — South America, Central America, Caribbean, Mexico *'' Dianleucauge'' Song & Zhu, 1994 — China *'' Diphya'' Nicolet, 1849 — Asia, South America, Africa *''Dolic ...

Spiders Described In 2014
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 ...
