The pugnacious burrowing scorpion (Opistophthalmus pugnax) is a species of South African scorpion.

Description

Length: up to 70 mm

These are muddy looking scorpions, characterized by corrugations on the last sternite, stiff hairs (setae) and highly recurved tarsal claws. Males have corrugations on the last two sternites.

Distribution and habitat

A fan-shaped burrow with an enlarged part for resting or consuming prey is constructed under rocks and other surface debris. It is a very common species on rocky outcrops and ridges in the north-central Free State and Gauteng provinces of South Africa.

Behaviour

Despite its species name, it is not particularly aggressive and very rarely enters houses. The female gives birth to litters of up to 25.
