Textrix Denticulata
''Textrix denticulata'', the toothed weaver, is a funnel web spider of the family Agelenidae found in much of Europe. It was described by the French entomologist Guillaume-Antoine Olivier in 1789. An older name coined by Martini & Goeze in 1778, ''Aranea cruciger'', has been declared a nomen oblitum, allowing Olivier's later name to stand. Description The male ''Textrix denticulata'' is similar to the female in general appearance. The carapace is dark brown with a light median band. The head is narrow, with steep sides, not unlike wolf spiders of the genus ''Pardosa''. The abdomen is dark brown with a light horse-shoe shaped marking towards the anterior which breaks down into a series of light spots towards the posterior. There are vague, somewhat reddish chevrons due to the relatively thinner coating of hairs between the horseshoe mark and the posterior spotting which causes the background colour of the abdomen to be visible. The legs are yellow-brown with dark annulations an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guillaume-Antoine Olivier
Guillaume-Antoine Olivier (; 19 January 1756, Les Arcs near Toulon – 1 October 1814, Lyon) was a French entomologist and naturalist. Life Olivier studied medicine in Montpellier, where he became good friends with Pierre Marie Auguste Broussonet. With Jean Guillaume Bruguière and Jean-Baptiste Lamarck . Jean-Baptiste-François Gigot d'Orcy later employed Olivier who was then able to travel to England and Holland meeting Thomas Martyn in London. In 1789 and 1790 he published the first two volumes of the ''Histoire naturelle des Coléoptères'' for Gigot d'Orcy, and simultaneously, thanks to Daubenton's recommendation, collaborated in the ''Dictionnaire de l'Histoire naturelle des Insectes, Papillons, Crustacés'' and collaborated in the creation of ''Journal d'Histoire Naturelle'' (1792). Afterwards, he served as a naturalist on a 6-year scientific journey that took him to Asia Minor, Persia, Egypt, Cyprus and Corfu. He returned to France in 1798 with a large collecti ...

Nomen Oblitum
In zoological nomenclature, a ''nomen oblitum'' (plural: ''nomina oblita''; Latin for "forgotten name") is a disused scientific name which has been declared to be obsolete (figuratively "forgotten") in favor of another "protected" name. In its present meaning, the ''nomen oblitum'' came into being with the fourth edition (1999) of the ''International Code of Zoological Nomenclature''. After 1 January 2000, a scientific name may be formally declared to be a ''nomen oblitum'' when it satisfy the following conditions: # No uses as a valid name in a scientific publication are known after 1899 (this criterion is taken on faith). # It is either a senior synonym (there is also a more recent name which applies to the same taxon, and which is in common use) or a senior homonym (it is spelled the same as another name, which is also in valid use). # The preferred junior synonym or homonym is shown to be in wide use, defined as appearing in 25 or more publications in the past 50 years (must ...

Agelenidae
The Agelenidae are a large family of spiders in the suborder Araneomorphae. Well-known examples include the common "grass spiders" of the genus ''Agelenopsis''. Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider (''Eratigena agrestis'') may be medically significant, and some evidence suggests it might cause necrotic lesions, but the matter remains subject to debate. The most widely accepted common name for members of the family is funnel weaver. Description The body length of the smallest Agelenidae spiders are about , excluding the legs, while the larger species grow to long. Some exceptionally large species, such as ''Eratigena atrica'', may reach in total leg span. Agelenids have eight eyes in two horizontal rows of four. Their cephalothorax, cephalothoraces narrow somewhat towards the front where the eyes are. Their abdomens are more or less oval, usually patterned with two rows of lines and spots. Some species have longitudinal lines on the dors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Entomologist
Entomology (from Ancient Greek ἔντομον (''éntomon''), meaning "insect", and -logy from λόγος (''lógos''), meaning "study") is the branch of zoology that focuses on insects. Those who study entomology are known as entomologists. In the past, the term ''insect'' was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. The field is also referred to as insectology in American English, while in British English insectology implies the study of the relationships between insects and humans. Over 1.3million insect species have been described by entomology. History Entomology is rooted in nearly all human cultures from prehistoric times, primarily in the context of agriculture (especially biological control and beekeeping). The natural Roman philosopher Pliny the Elder (23–79 CE) wrote a book on the kinds of insects, while the scientist of Kufa, ...

Friedrich Heinrich Wilhelm Martini
Friedrich Heinrich Wilhelm Martini (31 August 1729, Ohrdruf – 27 June 1778, Berlin) was a German physician, translator and conchologist. Martini practised medicine in Berlin. In 1769, he began the colour-illustrated shell book ''Neues systematisches Conchylien-Cabinet'', published by Gabriel Nikolaus Raspe at Nürnberg. He died following the publication of the third volume, after which the series was continued by Johann Hieronymus Chemnitz (1730–1800), who added eight volumes between 1779 and 1795. Because these volumes did not use the binomial system, the species names introduced are not considered valid. However, the specimens illustrated often became type specimens, because subsequently others referred to them when publishing valid descriptions. His shell collection was sold after his death but is now lost, probably deliberately disposed of in the 1970s. In 1773, Martini founded the Berlinische Gesellschaft Naturforschender Freunde, consisting of a group of natural histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann August Ephraim Goeze
Johann August Ephraim Goeze (; 28 May 1731 – 27 June 1793) was a German zoologist, born in Aschersleben. He is known for the discovery of tardigrades, also called water bears. He was the son of Johann Heinrich and Catherine Margarete (née Kirchhoff). He studied theology at University of Halle. He married Leopoldine Maria Keller in 1770, by whom he had four children. In 1751, he became a pastor in Aschersleben, in Quedlinburg, and later of in Quedlinburg in 1762, finally becoming first deacon of the seminary of Quedlinburg in 1787. He died in Quedlinburg. He did much work with aquatic invertebrates, particularly insects and worms. In 1784, Goeze perceived the similarities between the heads of tapeworms found in the human intestinal tract and the invaginated heads of '' Cysticercus cellulosae'' in pigs. In 1773, he was the first to describe tardigrades, naming them ''Kleiner Wasserbär'', meaning 'little water-bear'. Works *Goeze, J. A. E. 1776. Verzeichnisse der Namen von ...

Wolf Spider
Wolf spiders are members of the family Lycosidae (), named for their robust and agile hunting skills and excellent eyesight. They live mostly in solitude, hunt alone, and usually do not spin webs. Some are opportunistic hunters, pouncing upon prey as they find it or chasing it over short distances; others wait for passing prey in or near the mouth of a burrow. Wolf spiders resemble nursery web spiders (family Pisauridae), but wolf spiders carry their egg sacs by attaching them to their spinnerets, while the Pisauridae carry their egg sacs with their chelicerae and pedipalps. Two of the wolf spider's eight eyes are large and prominent; this distinguishes them from nursery web spiders, whose eyes are all of roughly equal size. This can also help distinguish them from the similar-looking grass spiders. Description The many genera of wolf spiders range in body size (legs not included) from less than . They have eight eyes arranged in three rows. The bottom row consists of fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pardosa
''Pardosa'' is a large genus of wolf spiders, commonly known as the thin-legged wolf spiders. It was first described by C. L. Koch, in 1847, with more than 500 described species that are found in all regions of the world. Description They are small to medium size wolf spiders, with clear median and lateral bands on the carapace. They have relatively long legs with long spines on the foot, which can be used to quickly identify some species.
