Diagnosis | Differential diagnosis: U. geyri is distinguished from U. thomasi and U. princepsby the longer and narrower tail (65.45–98.06 % of SVLin U. geyri vs. 25.00–36.16 % in U. thomasiand 34.62–52.55 % in U. princeps); from the species of the U. ocellata group and U. macfadyeniby the arrangement of the annuli of the tail: last 8–21 forming a continuous scale row each (U. ocellatagroup and U. macfadyeni) vs. 2–5 whorls forming a continuous scale row in U. geyri; from U. aegyptiaand U. occidentalisby the lower scale counts around midbody (238–322 in U. aegyptia, 297–301in U. occidentalis vs. 142–196 in U. geyri), from U. acanthinura, U. nigriventrisand U. dispar by its longer tail (65.45–98.06 % of SVLin U. geyri vs. 50.27–74.42 in U. acanthinura, 47.83–70 % in U. disparand 43.48–75.14 % in U. nigriventris). From U. alfredschmidtiit is distinguished by differences in the scalation of the flanks (enlarged triangular and imbricate scales in U. alfredschmidti vs. enlarged tubercular scales in U. geyri), as well as the complete black colouration of adult males in U. alfredschmidti. |
