Nosferattus Occultus
''Nosferattus occultus'' is a jumping spider. Etymology The epithet is Latin for "hidden" and refers to the embolus, which is hidden behind the edge of the tegulum. Appearance Males of ''N. occultus'' can be easily distinguished from the remaining species of the genus by the length of the embolus, coiled 3.5 times around the tegulum, and other characteristics. Males are almost 4 mm long, with females slightly larger. Distribution ''N. occultus'' occurs in the States of Maranhão and Ceará in Brazil Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America.

Jumping Spider
Jumping spiders are a group of spiders that constitute the family (biology), family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiders at 13% of all species. Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and Invertebrate trachea, tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the Anatomical terms of location, anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider f ...

Epithet
An epithet (, ), also byname, is a descriptive term (word or phrase) known for accompanying or occurring in place of a name and having entered common usage. It has various shades of meaning when applied to seemingly real or fictitious people, divinities, objects, and binomial nomenclature. It can also be a descriptive title: for example, Pallas Athena, Phoebus Apollo, Alfred the Great, Suleiman the Magnificent, and Władysław I the Elbow-high. Many English monarchs have traditional epithets: some of the best known are Edward the Confessor, William the Conqueror, Richard the Lionheart, Æthelred the Unready, John Lackland and Bloody Mary. The word ''epithet'' can also refer to an abusive, defamatory, or derogatory phrase. This use as a euphemism is criticized by Martin Manser and other proponents of linguistic prescription. H. W. Fowler complained that "epithet is suffering a vulgarization that is giving it an abusive imputation." Linguistics Epithets are sometimes at ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Embolism
An embolism is the lodging of an embolus, a blockage-causing piece of material, inside a blood vessel. The embolus may be a blood clot (thrombus), a fat globule ( fat embolism), a bubble of air or other gas (gas embolism), amniotic fluid (amniotic fluid embolism), or foreign material. An embolism can cause partial or total blockage of blood flow in the affected vessel. Such a blockage (vascular occlusion) may affect a part of the body distant from the origin of the embolus. An embolism in which the embolus is a piece of thrombus is called a thromboembolism. An embolism is usually a pathological event, caused by illness or injury. Sometimes it is created intentionally for a therapeutic reason, such as to stop bleeding or to kill a cancerous tumor by stopping its blood supply. Such therapy is called embolization. Classification There are different types of embolism, some of which are listed below. Embolism can be classified based on where it enters the circulation, either in ar ...

Tegulum
The two palpal bulbs – also known as palpal organs and genital bulbs – are the copulatory organs of a male spider. They are borne on the last segment of the pedipalps (the front "limbs" of a spider), giving the spider an appearance often described as like wearing boxing gloves. The palpal bulb does not actually produce sperm, being used only to transfer it to the female. Palpal bulbs are only fully developed in adult male spiders and are not completely visible until after the final moult. In the majority of species of spider, the bulbs have complex shapes and are important in identification. Structure The palpal bulb of a mature male spider is borne on the last segment of the pedipalp. This segment usually has touch-sensitive hairs (setae) with nerves leading to them. The bulb itself is entirely without nerves, and hence without sensory organs and muscles, since these depend on nerves for their functioning, although some spiders have one or two muscles external to the bulb a ...

Maranhão
Maranhão () is a state in Brazil. Located in the country's Northeast Region, it has a population of about 7 million and an area of . Clockwise from north, it borders on the Atlantic Ocean for 2,243 km and the states of Piauí, Tocantins and Pará. The people of Maranhão have a distinctive accent inside the common Northeastern Brazilian dialect. Maranhão is described in books such as '' The Land of the Palm Trees'' by Gonçalves Dias and ''Casa de Pensão'' by Aluísio Azevedo. The dunes of Lençóis are an important area of environmental preservation. Also of interest is the state capital of São Luís, designated a Unesco World Heritage Site. Another important conservation area is the Parnaíba River delta, between the states of Maranhão and Piauí, with its lagoons, desert dunes and deserted beaches or islands, such as the Caju island, which shelters rare birds. Geography The northern portion of the state is a heavily forested plain traversed by numerous rivers, ...

Ceará
Ceará (, pronounced locally as or ) is one of the 26 states of Brazil, located in the northeastern part of the country, on the Atlantic coast. It is the eighth-largest Brazilian State by population and the 17th by area. It is also one of the main tourist destinations in Brazil. The state capital is the city of Fortaleza, the country's fourth most populous city. The state has 4.3% of the Brazilian population and produces 2.1% of the Brazilian GDP. Literally, the name ''Ceará'' means "sings the jandaia". According to José de Alencar, one of the most important writers of Brazil and an authority in Tupi Guaraní, ''Ceará'' means turquoise or green waters. The state is best known for its extensive coastline, with of sand. There are also mountains and valleys producing tropical fruits. To the south, on the border of Paraíba, Pernambuco and Piauí, is the National Forest of Araripe. Geography Ceará has an area of . It is bounded on the north by the Atlantic Ocean, ...

Sitticini
The Sitticini are a tribe of spiders in the family Salticidae (jumping spiders). The tribe has been divided into two subtribes, Aillutticina, with five Neotropical genera, and Sitticina, with five genera from Eurasia and the Americas. One genus is unplaced within the tribe. The taxonomy of the tribe has been subject to considerable uncertainty. It was clarified in 2020. Description The group is now primarily defined by molecular phylogenetic analysis. However, members can be distinguished from other salticids by the fourth leg being much longer than the third and by the absence of the retromarginal cheliceral tooth. Taxonomy The group was first described by Eugène Simon in 1901, under the name "Sitticeae". It was treated as the subfamily Sitticinae by various authors before being reduced to the tribe Sitticini by Wayne Maddison in 2015. The taxonomy of the tribe has been subject to considerable uncertainty; generic boundaries were changed repeatedly between 2017 and 2020. ...

Spiders Of Brazil
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 ...
