Parabuthus transvaalicus is a dangerous, medically significant scorpion, which can both sting and spray its kurtoxin venom. [2] The first droplet of venom differs from the rest, and is referred to as "pre-venom". [4] A further potassium channel inhibitor, parabutoxin, has been isolated from the venom of P. transvaalicus.

Parabuthus, commonly known as the thick-tailed scorpion, is a genus of large and highly venomous Afrotropical scorpions, that show a preference for areas of low rainfall. [ 1 ] [ 3 ] Their stings are medically important and human fatalities have been recorded.
Pseudolychas is a genus of scorpion in the family Buthidae. Species of the genus are known as the pygmy-thicktail scorpions and are found in South Africa, Eswatini and Mozambique. Their venom is mild and not medically important. [1] Pseudolychas ochraceus reproduces by parthenogenesis. [1] [2]
Their vernacular name refers to the thick tails found in many Buthidae, especially in the Old World. The pedipalps, though, tend to be weak, slender, and tweezer-like. The Buthidae are generally rather cryptically colored, quite uniformly ochre to brown, but some are black or (like Centruroides and Uroplectes) more vividly colored.
Uroplectes is a genus of scorpions in the family Buthidae.They are known commonly as the lesser thick-tailed scorpions.There are about 40 species distributed in the Afrotropical realm. [1]
Parabuthus villosus, the black hairy thick-tailed scorpion, is a species of scorpion from southern Africa, where it ranges from the Northern Cape to Namibia. It is the largest species of the Buthidae , measuring up to 18 cm, [ 1 ] and its diet may include lizards and mice . [ 2 ]
Parabuthus granulatus, commonly known as the granulated thick-tailed scorpion, a large species of scorpion from the drier parts of southern Africa. It measures some 11.5 cm, and is dark yellow to brown in colour. It has a relatively small vesicle, but is one of the more venomous scorpion species of the region. [1]
It excavates a vertical burrow around 18 cm (7 in) long, generally located at the base of a tuft of grass or among multiple tufts. The scorpion takes 2–3 nights to complete this, using its pincers to loosen the ground and then pedipalps and pincers as spades to carry the soil away. [4] It eats dung beetles, which fall into its burrow. [4]
