Within the United Arab Emirates, this species is widespread throughout the sandy deserts, including the deep sands of the Rub' al Khali (Gardner 2013, Burriel-Carranza et al. in press). It occurs from sea level to 400 m asl.Globally, this species is widely distributed in the Arabian Peninsula (Saudi Arabia, Yemen, Oman, United Arab Emirates, Qatar and Kuwait) (Sindaco and Jeremäenko 2008), where it is found from sea level up to around 1,000 m asl. The species has been recorded from Khuzestan and Qeshm Island in Iran (Fahmi et al. 2009, Dakhteh et al. 2007), the latter citing work then in preparation. These records are not mentioned in a subsequent checklist for Iran, which recognizes S. scincus from Khuzestan (Šmíd et al. 2014). While the Qeshm record was accepted by Housseinen et al. (2013), this record is far from the species' known range and this distribution record has never been formally published (S.S. Housseinen Yousefkhani pers. comm. 2019). It is likely that this represents a misidentification of S. scincus (S.S. Housseinen Youssefkhani pers. comm. 2019). The occurrence of S. mitranus in Iran has subsequently been confirmed with a 2015 record from Bampour-Iranshahr, close to Bampour city in Sistan-Baluchistan, but it is thought that the species' range in Iran is very restricted (S.S. Housseinen Youssefkhani pers. comm. 2019).
