Background: Scorpions, as a group of venomous invertebrates, are distributed worldwide including the Middle East. These arthropods are distributed throughout Iran, are dangerous to humans and animals, and can cause severe damages and even death.
Methods: In this cross-sectional study, scorpions were collected from different parts in southern Iran such as Kohgiluyeh and Fars provinces using hand catch method with U.V torch. Morphological identification of scorpion specimens was done using specific keys.
Results: Besides different species of scorpions, Hottentotta jayakari Pocock, was identified in Amir Oncology Hospital, Shiraz city, Fars province, South of Iran, 1895.
Conclusion: Hottentotta jayakari is endemic in tropical regions and its existence in Shiraz with a mild climate seems unexpected. In addition, Amir Hospital is an oncology treatment center and this scorpion was caught on the hospital grounds. It is possible that more species can be identified in this province by conducting more studies.
