DistributionN Oman (mountains from the Jebel Akhdar to the East), 22-1683 m elevation.

Type locality: Wadi Bani Khalid, 647 m, Eastern Hajar (North Oman), 22.61609’N 59.09371.  
TypesHolotype: BMNH 2008.714, male from Wadi Bani Khalid, 647 m, Eastern Hajar (North Oman), 22.61609’N 59.09371’E WGS84, collected in May 2011 by S. Carranza, E. Gómez-Díaz and F. Amat (MorphoBank M99903–M99917; Fig. 12D). Paratypes: ONHM3706, male, same collecting data as Holotype (MorphoBank M99885–M99893); IBES7335, male, same collecting data as Holotype (MorphoBank M99894–M99902; Fig. 11D); IBES7336, female, same collecting data as Holotype (MorphoBank M99969–M99976). 
DiagnosisDiagnosis A medium-sized Hemidactylus with a maximum recorded SVL of 66.9 mm; with a mean of 14.2 (13–15) longitudinal rows of enlarged dorsal tubercles at mid-body; adhesive pads fairly broad, in adults maximum width of pad on the fourth toe about 0.4–0.5 of its length; lamellae under the 1st toe of pes mean 8.0 (7–9); lamellae under the 4th toe of pes mean 12.1 (11–14); preanal pores mean 5.5 (4–6); expanded subcaudal scales extending proximally as far as the second or third whorl after the vent and starting just after the hemipenial bulge in males; dorsum grey-buff with irregular small spots; a dark stripe from the nostril, through the eye, on to cheek above ear and often on to neck; tail with small irregular dark blotches basally and numerous transverse dark bands more distally, the total number being around 17. Underside of tail pale but large subcaudals may be suffused with grey formed by dark chromatophores that increase in intensity distally; underside of toe pads also grey.
Hemidactylus hajarensis is generally similar to H. persicus in the number of its moderately-sized dorsal tubercles across mid-body, and large adhesive pads on toes but differs from it in its reduced number of preanal pores in males (mean 5.5, 4–6, compared with mean 9.2, 8–11). Hemidactylus hajarensis differs from H. luqueorum sp. nov. in its smaller size (SVL mean 54 mm, max. 66.9 mm, compared with mean. 76.8 mm, max. 88 mm), and in having fewer lamellae under the 1st toe of pes (mean 8.0, 7–9, compared with mean 10.3, 10–11), and under the 4th toe of pes (mean 12.1, 11–14, compared with mean 13.6, 13–14).
