Tityus pachyurus is a species of arachnid endemic to Central America and South America.

Characteristics[]

Tityus pachyurus can grow from 6 to 9 cm in length, its pedipalps are reddish, while the fourth and fifth segments of the post-abdomen are dark and thicker, feeding is based on larvae of beetles (tenebrians) and cockroaches.^[1] this species occurs in Central America (Costa Rica and Panama) and in South America (Colombia), in Colombia this species occurs in the departments of Antioquia and Chocó. It is found mainly in tropical forests, urban regions and places with high tourist and industrial activity. like many scorpions, it's nocturnal.^[2]

Medical significance[]

It is the species responsible for the most serious accidents involving scorpions in Central America and Colombia, including children. In Colombia, we report a case of a 12-year-old boy, stung in the thigh, the victim had a lot of pain at the site, and the case quickly progressed to systemic effects, with myocardial dysfunction, cardiovascular collapse, cardiac arrest and pulmonary edema.^[3] This species has a median lethal dose of 4.8 mg / kg.^[1]
