(Pessa, 1935)

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. [1] 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 (subcutaneous injection).

<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

<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.

<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.
