The genus Liobuthus Birula, 1898 (Buthidae) is a rare, psammophilic genus with one species from Central Asia. Victor Fet and co-workers recently published a revision of the genus, and based on DNA-analysis and morphology, four new species are described.
Liobuthus atamuradovi (Turkmenistan)
Liobuthus danovi (Kazakhstan, Northern Turkmenistan, Uzbekistan)
Liobuthus shukurovi (Southwestern Tajikistan)
Liobuthus vachoni (Southern Kazakhstan)
An identification key for the five species in the genus is included.
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.
