Seven species of scorpions belonging to three families have been previously recorded from the Ilam Province of Iran: Androctonus crassicauda (Olivier, 1807), Compsobuthus matthiesseni (Birula, 1905), Hottentotta saulcyi (Simon, 1880), Mesobuthus eupeus phillipsii (Pocock, 1889), Razianus zarudnyi (Birula, 1903), Scorpio maurus townsendi (Pocock, 1900), and Hemiscorpius lepturus Peters, 1861. Collections made by a team organized by Shahrokh Navidpour (Razi Reference Laboratory of Scorpion Research, Razi Vaccine and Serum Research Institute, Ahvaz, Khoozestan, Iran) reveal seven other species recorded from the province for the first time: Apistobuthus susanae Lourenço, 1998, Buthacus macrocentrus (Ehrenberg, 1828), Compsobuthus jakesi Kovařík, 2003, Odontobuthus bidentatus Lourenço et Pézier, 2002, Orthochirus iranus Kovařík, 2004, Polisius persicus Fet, Capes et Sissom, 2001, and Vachoniolus iranus Navidpour, Kovařík, Soleglad et Fet, 2008. Also presented is a key to all species of scorpions found in the province.
