[2] Parabuthus transvaalicus is found in deserts, scrublands and semi-arid regions of Botswana, Mozambique, Zimbabwe, some parts of the Namib Desert and South Africa.

[3] Parabuthus transvaalicus is a dangerous, medically significant scorpion, which can both sting and spray its kurtoxin venom.

[4] A further potassium channel inhibitor, parabutoxin, has been isolated from the venom of P.
