Background: Scorpions are one of the most important medical arthropods in Iran. This study aimed to determine the fauna, spatial distribution and some morphological characteristics of these venomous arthropods in the study area.
Methods: Scorpions were collected using Ultra Violet light, rock rolling and digging methods in West Azerbaijan, East Azerbaijan, and Ardabil Provinces during 2015-2016. The specimens were preserved in 75% ethyl alcohol and transferred to the laboratory for species identification and morphological studies.
Results: Distribution maps were produced using ArcGIS 10.3. Totally, 368 specimens from two families of Buthidae (97.1%) and Scorpionidae (2.99%) were collected and identified as Mesobuthus eupeus (80.16%), Androctonus crassicauda (10.60%), M. caucasicus (4.89%), Hottentotta saulcyi (1.35%) and Scorpio maurus (2.99%).
Conclusion: The presence of medically important species, including the deadly black one in northwestern Iran requires health educational and control programs for reduction of these public health problems.
