| Comment | Status of Uromastyx temporalis unclear. Illustrations: WILMS (2002: 30) for sexual dimorphism and juveniles in U. acanthinura. Distribution: the populations of Uromastyx first named “acanthinura” for northern Chad and Sudan are now namedU. dispar (L. Chirio, pers. comm. 5 Apr 2012). Subspecies: WILMS et al. (2009) do not recognize subspecies of this species.Uromastyx acanthinura dispar and U. a. geyri are considered as a full species by WILMS & BÖHME 2001. Uromastyx acanthinura flavifasciata is considered as a subspecies of dispar by these authors. Uromastix acanthinura nigriventris ROTHSCHILD & HARTERT 1912 has been elevated to full species status. Diagnosis: U. acanthinura is distinguished from U. thomasi and U. princepsby the longer and narrower tail (50.27–74.42 % of SVLin U. acanthinura 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. 2–5 whorls forming a continuous scale row in U. acanthinura; from U. aegyptia and U. occidentalis by the lower scale counts around midbody (238–322 in U. aegyptia, 297–301 in U. occidentalisvs. 146–195 in U. acanthinura), from U. geyri and U. alfredschmidti by the shorter tail (50.27–74.42 % of SVLin U. acanthinura vs. 65.45–98.06 % in U. geyri and 79.31–87.26 % in U. alfredschmidti). Diagnostic characters between U. acanthinura and the subspecies of U. dispar are: Lower number of scales around midbody [145–195 (mean. 165.6) in U. acanthinura vs. 187–227 (mean: 205.0) in U. d. dispar]; lower number of ventrals [74–96 (mean. 83.1) in U. acanthinura vs. 88–118 (mean: 104.5) in U. d. flavifasciata] and lower number of subdigital scales [9–15 (mean: 12.7) in U. acanthinura vs. 15–18 (mean: 16.4) in U. d. maliensis]. U. acanthinura is differentiated from U. nigriventris by being much less colourful and lacking red, green and citreous colouration. |
