N2  - From an examination of specimens of the scorpion Isometroides Keyserling collected in Western Australia, South Australia, and New South Wales and a study of the literature, it is concluded that two described species must be regarded as one. I. angusticaudus Keyserling is considered a synonym of I. vescus (Karsch).   The genus represents a unique adaptive level, especially in its specialized feeding behaviour. It is distributed throughout the semi-arid inland. These facts make it difficult to find a geographically imposed isolation whereby the genus, once established, could have speciated.   Field observations on this rare scorpion are presented. It is widespread, occurring in woodland and semi-arid country. In habit it is terrestrial, vagrant, and is specialized for feeding on burrowing spiders.
