Tityus discrepans can grow up to 71 mm (males) and 60 mm (females), has a reddish-brown body and pedipalps, and light legs, juveniles can be light yellow-brown, with the rest of the body with black areas. Like several scorpions, it has nocturnal habits, feeds on spiders, forks, cockroaches, butterflies and has even been noted to prey on other scorpions.

Range and habitat

Tityus discrepans is found in Brazil, Suriname, Venezuela, Guyana and Trinidad and Tobago, inhabits wooded areas, under leaves and rocks, orchids, bromeliads, cracks and bark.[2] This species also occurs in human habitations, where it has already been reported on sheets, clothing and shoes.[3]

The female can produce 15-30 cubs, which are born fully developed, and are located on the mother's back.[4][2]

Medical significance

Tityus discrepans is considered a serious public health problem in Venezuela, being dangerous for all ages, especially children and the elderly, the sting of this species can result in piloerection, dyspnea, excessive salivation, cramps, fever and vomiting. In severe cases, heart failure, pulmonary edema and pancreatitis occur. The venom of this species is composed of 80 types of toxins, 6 of which are Bactridines, which inhibit the sodium channels in the nervous system,[5] and 10 of which are considered dangerous to humans, due to their low molecular weight, it travels quickly through the bloodstream and attacks the heart, lungs and pancreas.[6]
