Researchers report the first recorded presence of the scorpion species <em>Vachoniolus globimanus</em> in Jordan, specifically within the Wadi Rum Protected Area. This discovery extends the known distribution range of the genus <em>Vachoniolus</em>, which was previously documented only from Iran and parts of the Arabian Peninsula (Oman, Saudi Arabia, United Arab Emirates). The study employed morphological analysis, morphometric measurements, and taxonomic features to confirm the species identification. Additionally, ecological notes on the scorpion's habitat in Wadi Rum were provided, contributing valuable insights into its environmental preferences.
