Isometroides angusticaudus

Isometroides angusticaudus, also known as the slender spider-hunting scorpion, is a species of scorpion in the Buthidae family. It is native to Australia, and was first described by German arachnologist Eugen von Keyserling in 1885.

Description

This species grows to about 30 mm in length, smaller than the otherwise very similar I. vescus, with which it was once synonymised.

Distribution and habitat

The species has been recorded from South Australia, New South Wales and Victoria.

Behaviour

The scorpions are specialised nocturnal predators of trapdoor spiders, and are often found in the vacant burrows of their prey.
