Philipp Bertkau
Philipp Bertkau (11 January 1849 – 22 October 1894) was a German zoologist born in Cologne. He studied natural sciences at the University of Bonn, where in 1872 he earned his doctorate. In 1873, he became an assistant at the botanical institute in Munich, and during the following spring was an assistant at the zoological institute at Bonn. In 1882 he was appointed professor at the Agricultural Academy of Poppelsdorf, and in 1890 became curator at the Institute of Zoology and Comparative Anatomy. Bertkau is remembered for his work involving the anatomy and physiology of spiders, research on sense of smell in butterflies, and anatomical studies of hermaphroditic arthropods. At Bonn he was secretary of ''Bonner Gesellschaft für Naturgeschichte'' (Bonn Society of Natural History). He is the taxonomic authority of the families Anyphaenidae, Hahniidae, Sparassidae and Zoropsidae, and of the genera '' Ancylometes'', ''Chalcoscirtus'', '' Comaroma'' and '' Diplocephalus''.

Type Species
In International_Code_of_Zoological_Nomenclature, 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 (biology), type wiktionary:en:specimen, specimen (or specimens). 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 International Code of Nomenclature for algae, fungi, and plants, 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 with 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 suc ...

Spiders Of Argentina
Spiders (order Araneae) are air-breathing arthropods that have eight limbs, 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 Antarctica, and have become established in nearly every land habitat. , 53,034 spider species in 136 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ctenidae Genera
Wandering spiders (''Ctenidae'') are a family of spiders that includes the Brazilian wandering spiders. These spiders have a distinctive longitudinal groove on the top-rear of their oval carapace similar to those of the Amaurobiidae. They are highly defensive and venomous nocturnal hunters. Wandering spiders are known to hunt large prey, for example hylid species '' Dendropsophus branneri.'' Despite their notoriety for being dangerous, only a few members of '' Phoneutria'' have venom known to be hazardous to humans, but the venoms of this family are poorly known, so all larger ctenids should be treated with caution. General , the 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.

Charles Athanase Walckenaer
Baron Charles Athanase Walckenaer (25 December 1771 – 28 April 1852) was a French civil servant, writer, man of letters, and scientist. He was a polymath and wrote extensively on geography, natural history, and literature. Major contributions included his multi-volume natural histories of arachnids and insects, some published in collaboration with others. He was made a baron in 1823. Biography Walckenaer was born in Paris and after losing his parents at an early age he was raised by his uncle Charles-Nicolas Duclos Dufresnoy, a notary in the court of Louis XVI. His uncle's elite and educated circle made an impression on the young boy and he was sent to study at the universities of Oxford and Glasgow. Dufresnoy was guillotined in 1794 following the French Revolution for being associated with the regime. In 1793, Walckenaer was appointed head of the military transports in the Pyrenees, after which he pursued technical studies at the École Nationale des Ponts et Chaussées an ...
