Urodacus armatus, also known as the yellow sand scorpion or inland desert scorpion, is a species of scorpion in the Urodacidae family. It is native to Australia. It was first described in 1888 by British zoologist Reginald Innes Pocock. [1]
The species grows to 30–60 mm in length. Colouring is usually light sandy with dark red leg joints. [2]
The species is found over much of arid inland Australia on a variety of soils. [2]
The scorpions build short burrows and hunt small invertebrates through both active foraging and by ambushing their prey from the branches and foliage of low vegetation. [2]
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies.
Uropygi is an arachnid order comprising invertebrates commonly known as whip scorpions or vinegaroons. They are often called uropygids. The name "whip scorpion" refers to their resemblance to true scorpions and possession of a whiplike tail, and "vinegaroon" refers to their ability when attacked to discharge an offensive, vinegar-smelling liquid, which contains acetic acid. The order may also be called Thelyphonida. Both names, Uropygi and Thelyphonida, may be used either in a narrow sense for the order of whip scorpions, or in a broad sense which includes the order Schizomida.
Reginald Innes Pocock F.R.S. was a British zoologist.
The taxonomy of scorpions deals with the classification of this predatory arthropod into 13 extant families and about 1,400 described species and subspecies. In addition, 111 described taxa of extinct scorpions are known.

Formerly a subfamily (Urodacinae) of the Scorpionidae, it was later raised to family rank. Its sister taxon is the monotypic family Heteroscorpionidae, the species of which are confined to Madagascar.
