DiagnosisDiagnosis: Uromastyx yemenensis sp. nov. is a medium-sized member of the U. ocellata group, which is distinguished from the more primitive U. asmussi, U. loricata and U. hardwickii by the absence of intercalary scales between the whorls of the dorsal surface of its tail; from U. thomasi and U. princeps by the longer tail and from all other species of the genus (with the exception of U. ocellata, U. ornata, U. benti and U. macfadyeni) by the arrangement of the whorls of the tail. In U. yemenensis as well as in the four above mentioned species the last 8–21 whorls each consists of a simple continuous series of large scales, while in all other Uromastyx species only the last 2–5 whorls are like this. The new species differs from U. ocellata, U. ornata and U. macfadyeni in lacking femoral- and preanal pores. Uromastyx yemenensis differs from its sister species U. benti in having smaller and more scales around midbody (192.53 +/-16.63 in U. yemenensis vs. 160.05 +/- 8.98 in U. benti) and smaller and more ventrals (87.61 +/-5.66 in U. yemenensis vs. 74 +/-4.02 in U. benti).
