Fauna and Geographical Distribution of Scorpions in Ilam Province, South Western Iran

Abstract

Background: Scorpions’ stings and their own mortalities place them among the most important health and medical problems. The dreadful features and especially their poisonous stings are considered a major cause of human stress and abhorrence/phobia. The current study aimed to study the scorpion fauna of Ilam Province, south western Iran in order to manage scorpionism related problems.
Methods: In this field-laboratory investigation during March 2014 to February 2015, different parts of Ilam Province were surveyed. Nine sampling parts were selected based on geographical situation, scorpionism reports, weather, flora, and local data. Capturing scorpion was done employing a black light, and a long forceps from dusk to mid­night. The collected scorpions were placed to 70% ethyl alcohol. All specimens were determined based on the valid taxonomic keys, furthermore their sexes were studied.
Results: Out of the 391 collected scorpions, 11 species were identified as follows: Hottentotta saulcyi, Mesobuthus eupeus, Compsobuthus matthiesseni, Razianus zarudnyi, Hemiscorpius lepturus, Androctonus crassicauda, Or­thochirus iranus, Odontobuthus bidentatus, Buthacus macrocentrus, Scorpio maurus, and Polisius persicus.
Conclusion: Eleven species of Buthidae, Scorpionidae and Hemiscorpiidae families from high risk areas were iden­tified. Despite the low surface of the province, such different species reveals a diverse scorpion fauna that, in turn, shows good and suitable habits of scorpions, as considered by health staff.
