Buthidae

The Buthidae are the largest family of scorpions, containing about 80 genera and over 800 species as of mid-2008. Its members are known as, for example, fat-tailed scorpions and bark scorpions. A few very large genera (Ananteris, Centruroides, Compsobuthus, or Tityus) are known, but a high number of species-poor or monotypic ones also exist.[2] New taxa are being described at a rate of several to several dozen new species per year.[2] They occur in the warmer parts of every major landmass on Earth, except on New Zealand.[2] Together with the Microcharmidae, the Buthidae make up the superfamily Buthoidea. The family was established by Carl Ludwig Koch in 1837.[2]
