Abstract

The taxonomy of buthid scorpions belonging to the genus Leiurus Ehrenberg, 1828 is reviewed. Four new species are described from the Arabian Peninsula: L. macroctenus sp. n. from coastal fog deserts in Oman; L. haenggii sp. n. from mountains of the Red Sea coast, Hadramaut and Dhofar, in Saudi Arabia, Yemen and Oman; L. arabicus sp. n. from the central Najd Plateau and eastern plains in Saudi Arabia; and L. heberti sp. n. from Jabal Samhan in Oman. L. brachycentrus (Ehrenberg, 1829) stat. n. from the Tihamah plain of the Red Sea coast in Saudi Arabia and Yemen is restored from synonymy and redescribed. Leiurus nasheri Kovařík, 2007 was found to be a junior synonym of L. brachycentrus stat. n. L. quinquestriatus hebraeus (Birula, 1908) is elevated to species level as L. hebraeus (Birula, 1908) stat. n. Revised diagnoses are given for L. quinquestriatus (Ehrenberg, 1828), L. abdullahbayrami Yağmur, Koç et Kunt, 2009, L. jordanensis Lourenço, Modrý et Amr, 2002, and L. hebraeus (Birula, 1908). Key characters used to diagnose and separate species include morphometrics, granulation, tricho-bothriotaxy, tarsal setation, dentition of metasomal carinae and color pattern. Detailed illustrations are provided and the affinities and biogeography of the genus are discussed.
