| Comment | Etymology: Named after its distribution in Egypt. One of the largest species of the genus with a total length of up to 76 cm. Type species: Stellio spinipes DAUDIN 1802 (= Uromastyx aegyptia) is the type species of the genus Uromastyx MERREM 1820. Original definition (genus): Cauda squamis magnis crassis aculeatis verticillata” (Tail annulated by large, thick and spiny scales) (MERREM1820). Note that this definition appears to be the new definition by WILMS et al. (2009) excluding the new genus Saara. Diagnosis (genus Uromastyx s. str.): Acrodont dentition, with the premaxillary bone forming in adult specimens a sharp, tooth- like structure replacing the incisive teeth. Tail scalation arranged in distinct whorls, which are not separated by intercalary scales dorsally. Differential diagnosis (species): U. aegyptia is distinguished from U. thomasi and U. princeps by the longer tail (60.18–102.83 % of SVL in U. aegyptia vs. 25.00–36.16 % in U. thomasi and 34.62–52.55 % in U. princeps); from the species of the U. ocellata group and from U. macfadyeni by the arrangement of the annuli of the tail: last 8–21 forming a continuous scale row each (U. ocellata group and U. macfadyeni) vs. 2–8 whorls forming a continuous scale row in U. aegyptia; from the species of the U. acanthinura group by more scales around midbody (238–322 in U. aegyptia vs. 142–231 in the species of the U. acanthinura group). U. aegyptia is distinguished from U. occidentalis by having preanofemoral pores. Differential diagnosis (aegyptia): The nominotypic subspecies is distinguished from U. a. microlepisby having enlarged tubercular scales scattered over the scalation of the flanks and by lower scale counts. It is distinguished from U. a. leptieniby a different juvenile colour pattern and a high- er number of ventrals (see WILMS& BÖHME2000 a). Differential diagnosis (leptieni): Uromastyx a. leptieni is distinguished from aegyptiaand microlepisby a different juvenile colour pattern and a lower number of ventrals (see WILMS & BÖHME 2000 a). Differential diagnosis (microlepis): Uromastyx a. microlepis is distinguished from U. a. aegyptia by lacking enlarged tubercular scales scattered over the scalation of the flanks and by smaller scales. It is distinguished from U. a. leptieni by a different juvenile colour pattern and a higher number of ventrals (see WILMS & BÖHME 2000 a). |
