Friedrich Dahl
Karl Friedrich Theodor Dahl (June 24, 1856 in Rosenhofer Brök north of Dahme, Holstein – June 29, 1929 in Greifswald) was a German zoologist, and in particular an arachnologist. The son of a farmer, Dahl studied at the universities of Leipzig, Freiburg, Berlin and Kiel. His dissertation (1884) was "''Beiträge zur Kenntnis des Baus und der Funktion der Insektenbeine''". He became a ''Privatdozent'' in 1887; with a habilitation thesis "''Ueber die Cytheriden der westlichen Ostsee''". Around this time he traveled to the Baltic states and (1896–1897) to the Bismarck Archipelago near New Guinea. He was also interested in biogeography. On April 1, 1898 Dahl became curator of arachnids at the '' Museum für Naturkunde'' in Berlin, where he worked under his former teacher, the then museum director Karl Möbius. Dahl remained in Berlin until he retired, and his type collection is held in that museum. Although he described in many animal groups, Dahl concentrated on spide ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Spiders Of Asia
Spiders (order (biology), order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude spider silk, silk. They are the largest order of arachnids and rank seventh in total species diversity among all Order (biology), 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 Family (biology), families have been recorded by Taxonomy (biology), 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 segmentation (biology), segments are fused into two Tagma (biology), tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical Gl ...

Araneomorphae Genera
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:Che ...

Niklas Westring
Niklas Westring (13 November 1797, in Gothenburg – 28 January 1882) was a Swedish entomologist and arachnologist. He started out with the intention to study medicine but this was frustrated by the death of his father. His full-time profession from 1816 was as a customs officer in Gothenburg, where he was customs administrator from 1834 to 1856. When he retired he spent most of his time working on natural history, especially from 1840 to 1862, during which time he also became a conservator at the Göteborg Natural History Museum. He is best known for his book ''Araneae suecicae descriptae'' in 1862 in which he described 308 species of spider found in Sweden. Of these, 124 had already been described by Carl Linnaeus, Charles De Geer and Carl Jakob Sundevall. He appears to have been something of a mentor to Tamerlan Thorell who lived in Gothernborg until he went to university at Uppsala and was familiar with Westring's collection of spiders and how to identify them since he had be ...

James Henry Emerton
James Henry Emerton (March 31, 1847 – December 5, 1931) was an American arachnologist and illustrator. Early life Emerton was born at Salem, Massachusetts, on March 31, 1847. He was rather frail, and a young helper in his father's drug store, George F. Markoe, interested the boy in outdoor life. They collected plants, insects and shore invertebrates and at the age of fifteen he was frequently visiting the Essex Institute, where he became acquainted with A. S. Packard, F. W. Putnam, John Robinson, Caleb Cooke, and others who later became more or less prominent students of natural history. From the first, he showed much skill in drawing and made sketches of a great variety of natural objects. Of these early drawings, there are many in Packard's ''Guide'' and forty quarto plates in Watson and Eaton ''Botany of the Fortieth Parallel'' published in 1871. Professional life He was elected to the Boston Society of Natural History in 1870, and later, 1873-1874 was an assistant in the Mu ...
