Graeme Lowe recently published a study of the Androctonus Ehrenberg, 1828 (Buthidae) populations in Oman and two new species are described.
Androctonus ammophilus Lowe, 2025 (Oman, Saudi Arabia and United Arab Emirates)
Androctonus omanensis Lowe, 2025 (Oman)
The biogeography and speciation of Androctonus in this region is discussed.
Abstract:
The taxonomic position of Androctonus populations in Oman was investigated by analyzing morphological variation in a comprehensive sample representing 150 records gathered from 95 localities spread throughout the country. Two new allopatric species are described, separated by multivariate morphometric analysis and meristic characters: (1) A. omanensis sp. n., distributed across most of Oman, is characterized by wider, deeper metasomal segments IV–V, shorter legs, more robust pedipalps, more granules on lateral inframedian carinae of metasoma II–III, and sparser setation on basitarsal spurs; and (2) A. ammophilus sp. n., distributed in the dunes of the Rub’ al-Khali (Empty Quarter) of northwest Oman, and adjacent Saudi Arabia and United Arab Emirates, is characterized by narrower, shallower metasomal segments IV–V, longer legs, more elongate pedipalps, fewer granules on lateral inframedian carinae of metasoma II–III, and denser setation on basitarsal spurs. The emergence of the Rub’ al-Khali sand system during Pleistocene glaciations, and the transition to hyper-arid conditions in the region, are hypothesized to be abiotic factors promoting ecological speciation of A. ammophilus sp. n., and vicariant speciation of A. omanensis sp. n.
