Granulated Thick-Tailed Scorpion
Africa (Angola, Botswana, Namibia, South-Africa, Zimbabwe).
One of the larger species of Parabuthus, P. granulatus is found mainly in
dry habitats (receiving less than 600 mm of rain per year) in South Africa
and Namibia. It digs a shallow burrow at the base of shrubs in sandy to
consolidated sandy soils, but is also known to dig a shallow scrape under
rocks in soil of widely variable hardness and texture. It may also be found
in and around human dwellings in these areas.

venom). The use of antivenom for serious cases is
A study (ses internet link below) reports of a LD50
value of 1.56 mg/kg for this species (other Parabuthus
species in South Africa had LD 50 values in excess of 20
This species can not squirt venom.
Both studies conclude that P. granulatus is
the most important venomous scorpion in South Africa.
