Abstract
The rare Central Asian psammophilic scorpion genus, Liobuthus Birula, 1898 (Scorpiones: Buthidae), is revised. Five species are delineated according to results from three species delimitation approaches using mitochondrial DNA. Results are supported by diagnostic morphology, including an assessment of the distinctive neobothriotaxy. The type species, L. kessleri Birula, 1898, is confirmed for Iran (northeast), Turkmenistan and Uzbekistan (south). Four new species are described: L. atamuradovi sp. n. (Turkmenistan), L. danovi sp. n. (Kazakhstan, northern Turkmenistan, Uzbekistan), L. shukurovi sp. n. (southwestern Tajikistan), and L. vachoni sp. n. (southern Kazakhstan), The unique additive neobothriotaxy (on both pedipalp femur and patella) first discovered by Vachon (1958) is confirmed and analyzed.
