Tityus tenuicauda is a species of scorpions in the family Buthidae. This species was believed to be endemic to the island of Trinidad in Trinidad and Tobago. The distribution range of T. tenuicauda has been extended westward until Las Melenas, a location in the western side of Paria Peninsula National Park, Sucre State, northeastern Venezuela.[ citation needed ]

Trinidad and Tobago are continental islands with a geologically very recent history of direct land bridge connection to South America. As a result, unlike most of the Caribbean Islands, Trinidad and Tobago supports a primarily South American flora and fauna and has greater diversity of plant and animal species than the Antilles. However, rates of endemism are lower than in the rest of the Caribbean because there has been less time for genetic isolation from mainland populations because of the history of land bridge connections and hence fewer opportunities for speciation, and so a greater proportion of the species in Trinidad and Tobago are also found on the South American mainland. Trinidad is nearer to mainland South America and has been directly connected to the mainland via land bridges more often and for longer periods than Tobago. This, as well as Trinidad's larger size and more varied topography and hydrology compared to that of Tobago allow greater species and ecosystem diversity on the former compared to that on the later of the islands.

Tityustoxin is a toxin found in the venom of scorpions from the subfamily Tityinae. By binding to voltage-dependent sodium ion channels and potassium channels, they cause sialorrhea, lacrimation and rhinorrhea.

<span class="mw-page-title-main">Buthidae</span> Family of scorpions

The Buthidae are the largest family of scorpions, containing about 100 genera and 1339 species as of 2022. A few very large genera are known, but a high number of species-poor or monotypic ones also exist. New taxa are being described at a rate of several new species per year. They have a cosmopolitan distribution throughout tropical and subtropical environments worldwide. Together with four other families, the Buthidae make up the superfamily Buthoidea. The family was established by Carl Ludwig Koch in 1837.

<i>Centruroides</i> Genus of scorpions

Centruroides is a genus of scorpions of the family Buthidae. Several North American species are known by the common vernacular name bark scorpion. Numerous species are extensively found throughout the southern United States, Mexico, Central America, the Antilles and northern South America. Some are known for their interesting patterning or large size ; most if not all fluoresce strongly under ultraviolet illumination, except after moulting. They contain several highly venomous species, and fatalities are known to occur. The venom of the Mexican scorpion Centruroides limpidus limpidus contains the neurotoxins Cll1 and Cll2.

<i>Tityus</i> (genus) Genus of scorpions

Tityus is a large genus of thick-tailed scorpions, the namesake of its subfamily Tityinae. As of 2021, Tityus contains more than 220 described species distributed in Central America and South America, from Costa Rica to Argentina. Species in the genus Tityus have been studied for hundreds of years, long before the taxonomic classification was put in place. Tityus tend to be of medium size for scorpions, roughly 50 to 70 millimeters long. They are dark brown or red in color, and can exhibit sexual dimorphism. They can live in a variety of environments, ranging from urban to arid mountains to the Amazon Rainforest. Tityus scorpions are best known for their venom and potent sting. The genus contains several dangerously venomous scorpions, the best known of which is the Brazilian yellow scorpion, T. serrulatus. Its venom can cause severe illness, and in the young, old and infirm even death. Some experts have argued that the genus as a whole may be paraphyletic, which could explain the knowledge gaps related to Tityus

Tityus pintodarochai is a species of scorpion belonging to the family Buthidae. It is only known from a single female collected in Paraná state, Brazil.

<span class="mw-page-title-main">Scorpion sting</span> Medical condition

A scorpion sting is an injury caused by the stinger of a scorpion resulting in the medical condition known as scorpionism, which may vary in severity. The anatomical part of the scorpion that delivers the sting is called a "telson". In typical cases, scorpion stings usually result in pain, paresthesia, and variable swelling. In serious cases, scorpion stings may involve the envenomation of humans by toxic scorpions, which may result in extreme pain, serious illness, or even death depending on the toxicity of the venom.

<i>Tityus serrulatus</i> Species of scorpion

Tityus serrulatus, the Brazilian yellow scorpion, is a species of scorpion of the family Buthidae. It is native to Brazil, and its venom is extremely toxic. It is the most dangerous scorpion in South America and is responsible for the most fatal cases.

Tityus fasciolatus is a species of scorpion from the family Buthidae. The species are 4.5–8.5 centimetres (1.8–3.3 in) in length and are yellowish-brown coloured. They also have three dark stripes over the mesosoma with either yellowish or orange pedipalps, which have dark spots as well. Their first to third segments of metasoma is yellowish-orange, with the fourth one being reddish. Their fifth and final segment id dark red coloured. The species have yellow coloured legs which have dark spots, which are the same as on pedilap. Their tarsus is dark in colour with pectines that have 17-25 teeth, in which they have 16-18 rows of granules. T. fasciolatus is a species of medical importance, its venom is molecular and very similar to T. serrulatus, its venom contains at least 10 toxic fractions, with molecular masses ranging from 6 to 10-80 kDa, the LD50 for this species is 2.984 mg / kg.

<i>Tityus stigmurus</i> Species of scorpion

Tityus stigmurus is a species of scorpion from the family Buthidae that can be found in Brazil. The species are 4.5–6 centimetres (1.8–2.4 in) in length and are either golden-tan or yellowish-brown coloured. It takes them a year to mature into an adult, which makes them a fast-growing species. They also have a dark stripe over the mesosoma with either yellowish or orange pedipalps.

<i>Uroplectes</i> Genus of scorpions

<i>Tityus exstinctus</i> Species of scorpion

Tityus exstinctus is an extinct species of scorpion belonging to the family Buthidae. It is only known from a single male collected in 1884 in the northern range of Martinique. The species epithet based on the fact that this taxon was already extinct when it was described.
