A study of fauna of scorpions in Kohkilueyeh & Boirahmad and Chaharmahal-e-Bakhtiari provinces

Study on scorpion is limited and very poor in Iran. The most regions of country have not been studied concerning the existence of scorpions and their biology. At present work the fauna of scorpions in Kohkilueyeh & Boirahmad and Chaharmahal-e-Bakhtiari provinces were investigated in 1378. The specimens of scorpions were collected during day time to search under rocks, barks and other surface debris, and also to dig the rodent & insect nests and crevices of land. Collected scorpions in order to determine of their taxa, were studied in laboratory. Therefore, 7 species including A crassicauda, B. schach, M. eupeus, O. scrobiculosus, C. matthiesseni and R. zarudnyi from buthid family and H. lepturus from scorpionid family were identified in these provinces. Likewise some ecological characters of species, such as diversity, geographical distribution, density and homing behaviours were investigated. The highest diversity of identified species occurs in subtropical regions, lied in the south of these two provinces, and decreases toward the coldest regions in the north. The species H. lepturus, B. schach and M. eupeus are dominant and widely distributed scorpions in these regions. It is necessary to mention that the three described species and A. crassicauda are dangerous scorpions in these countries.
