Comparisons: Hemidactylus sassanidianus sp.n. differs from H. persicus (based on original description by Anderon 1872) by: (1) Dorsal tubercles in H. sassanidianus sp.n. are not strongly keeled and in some parts tubercles are not keeled, in contrast they are strongly keeled in H. persicus. (2) Heterogeneity of dorsal tubercles occurred in all specimens of H. sassanidianus sp.n., in contrast to original description of H. persicus. (3) Size of tubercles in H. sassanidianus sp.n. is smaller than H. persicus, about 0.4 of ear opening vs. 0.5 ear opening. (4) Five or six tubercles in each row of the tail in H. sassanidianus sp.n., and in contrast H. persicus have seven tubercles in each row of the tail. (5) Dorsal body of H. sassanidianus sp.n. covered by spots (not bars), in contrast dorsal body in H. persicus is covered by transverse narrow band. More differences between H. sassanidianus sp.n. and H. persicus (based on original description and Anderson 1999): (6) H. persicus only has two postmentals (in all populations; there are no records in the literature), in contrast H. sassanidianus sp.n. has 2–4 postmentals. (7) In Anderson’s work on H. persicus inhabiting Iran, he reported 9–11 preanal pores, which is clearly more than H. sassanidianus sp.n. (6–8). (8) Tail sharp in H. sassanidianus sp.n., and not sharp in H. persicus. Additional differences with H. persicus include: number of postmentals (2–4 vs. 2), mental trihedral (vs. pentagonal); relatively fewer precloacal pores in males (6–8 vs. 9–11); number of lamellae under the first digit of the pes (6–9 vs. 8–9); body size of H. sassanidianus sp.n. males (54.7) smaller than females (56.4), this is in contrast to H. persicus (males: 59; females: 51.4); head longer (HL/SVL: 0.3 vs. 0.24), elongated (HW/HL: 0.64 vs. 0.8), and more flattened (HH/HL: 0.4 vs. 0.49) [Carranza and Arnold 2012]; sexual dimorphism in head size (HL, HW, and HD) occurs for H. persicus (males significantly larger than females), this is in contrast to H. sassanidianus sp.n., and this is true for more characters (Table 4). Easily differentiated from H. romeshkanicus by number of precloacal pores (6–8 vs. 12), other differences: smaller body size, number of supralabials, and dorsal tubercle shape (not trihedral vs. enlarged trihedral). It is different from H. robustus by larger body size in both sexes combined (48–63 vs. 32–50) and in males (54.7 vs. 41.8) and females (56.4 vs. 43.6); more lamellae under the 1st (8.5 vs. 6.1) and 4th (12.8 vs. 10.1) digits of the pes; more supralabials (11.8 vs. 9.4); and greater number of precloacal pores (7.4 vs. 6.1) [Carranza and Arnold 2012; Šmíd et al. 2013a, 2015] (Table 2). Different from H. achaemenidicus sp.n. by larger body size (48–63 vs. 28–39), tail, dorsal tubercle rows, number of lamellae under digits of pes, labials, and postmentals (see Table 2). Different from H. flaviviridis by presence of dorsal tubercles and without femoral pores. More comparisons are shown in Table 2.
