Parabuthus granulatus (Granulated thick-tailed scorpion) The Granulated thick-tailed scorpion is large, about 115 mm in length and dark yellow to brown colour. In contrast to many other genera, no data is available on the venom composition of scorpions belonging to the genus Parabuthus. In contrast to Mesobuthus (= Hottentotta), Leiurus and Tityus venoms, Parabuthus venom appears to cause mainly neuromuscular effects. A novel peptide named Pg8 was purified from the venom of the South African scorpion Parabuthus granulatus and its primary structure was determined. It can be found as far North and far South on the Western side of South Africa, the whole of Namibia and the whole of Botswana.

Parabuthus granulatus is the most medically important venomous scorpion in South Africa, with potentially life-threatening venom (Newlands, 1974; M�ller, 1992). Parabuthus capensis was the alleged culprit of the fourth death but as the specimen was lost it cannot be verified. In one study, 42 serious cases was reported with 4 fatal dry habitats (receiving less than 600 mm of rain per year) in South Africa Blanca I. García-Gómez, Timoteo C. Olamendi-Portugal, Jorge Paniagua, Jurg van der Walt, Karin Dyason and Lourival D.

P. granulatus lives in burrow excavations at the base of shrubs and under stones in consolidated sandy soils. When disturbed it can squirt venom from the sting over a distance of about a metre. The gene coding for this peptide was cloned from a cDNA library. Stimulation of the autonomic nervous system through the release of endogenous catecholamines and acetylcholine, as observed following Mesobuthus (= Hottentotta), Leiurus and Tityus stings, is not as marked with Parabuthus stings. In addition P. raudus is said to possess the ability to spray venom when provoked extremely (LEEMING 2003). The venom is more toxic than Parabuthus transvaalicus.
