|Diagnosis||Diagnosis. A member of the Arabian radiation of the Arid clade of Hemidactylus with the following combination of characters: (1) medium size with SVL ranging between 43.0 and 48.5 mm in males and 38.3 and 51.1 mm in females; (2) long and narrow head not wider than the body in its widest part (HL=23–28 % of SVL, HW=7.9±1.3 mm in males, 7.6 ± 1.0 mm in females); (3) large anterior postmentals usu- ally in wide mutual median contact (96 % of specimens) and in contact with the first and second infralabial (at least on one side in 96 % of specimens); (4) uppermost nasals separated by an inserted scale in 87 % of specimens; (5) 7–9 infralabials and 7–11 supralabials; (6) dorsum with enlarged tubercles in 12–16 longitudinal rows, the tubercles are not keeled or, if so, only the vertebral ones; (7) males with 6 preanal pores; (8) 5–7 lamellae under the first toe and 9–11 under the fourth toe; (9) enlarged tile-like subcaudals; (10) beige background colora- tion with dark blotches in irregular vertebral and paravertebral rows that form X-shaped markings, head with distinct dark band from the nostril through eye to the ear, parietal and temporal regions with irregular dark markings which can be absent in some individuals, tail with 9–12 dark bands that grow in intensity towards the tail tip, and body underside creamy whitish.|
Differential diagnosis. Hemidactylus asirensis sp. n. differs significantly from its sister species, H. granosus, in the head shape; it has shorter and narrower head (HL 10.7 ± 1.3 vs. 12.3±1.1 mm, t test t=−4.085, p<0.001; HW 7.8±1.2 vs. 9.3±0.8 mm, t test t=−4.407, p<0.001; Fig. S2) and in the degree of keeling of the dorsal tubercles (H. asirensis sp. n. has flat unkeeled tubercles while H. granosus strongly keeled). The two species also differ in the number of lamellae under toes; H. asirensis sp. n. has 6.2 ± 0.4 (range 5–7) lamellae on the first toe while H. granosus has 7.4 ± 0.5 (7–8) (t test t = −8.681, p < 0.001) and 10.1 ± 0.6 (9–11) on the fourth toe while H. granosus has 11.6 ± 0.7 (10–13) (t test t = −7.051, p < 0.001). The differences from H. alfarraji sp. n. are described above. A comparison of metric and meristic variables with the other Hemidactylus species form SW Arabia is given in ŠMÍD et al. 2016 (Table S4).
