Parabuthus transvaalicus (known as the Transvaal thick-tailed scorpion, dark scorpion, giant deathstalker, or South African flat tail) is a species of venomous scorpion from dry parts of southern Africa.
Parabuthus transvaalicus grows to a length of 90–110 millimetres (3.5–4.3 in), and is dark brown or black in colour, so it is also known as the Black Thick-Tailed scorpion. Its pincers are thin, but its tail is thickened, with the sting segment being as wide as the rest of the tail. It is nocturnal, resting in a shallow burrow under rocks during the day. It resembles its congener P. villosus, which is less strictly nocturnal, hairier and has a more westerly distribution. The species is the largest (measuring up to 18 cm) and only diurnal Buthid in the world.
