| Diagnosis | Diagnosis. A Pseudotrapelus species forming a clade together with P. sinaitus and P. chlodnickii, with the following combination of morphological and genetic characters: (1) large size with a total length of 200–203 mm and SVL 70.7–76.6 mm; (2) 14–19 upper and 14–18 lower labial scales; (3) ear opening very large, oval, rimmed antero-dorsally by conical scales of different sizes that give it a serrated appearance; (4) scales in the occipital area predominantly not enlarged; (5) heterogeneous dorsal scales with the mid-dorsals being distinctly keeled and larger than the scales on the flanks; (6) one continuous row of 4–7 precloacal pores in both sexes; (7) 3rd toe longer than the 4th; (8) tail scales not arranged in whorls; (9) body and tail beige-brown in life with dark brown or orange transverse bars, the first on the nape, the second and the most prominent one in the scapular region, the third at midbody, the fourth in front of the insertion of the hind limbs, the fifth at the tail base; and the tail with regular dark bars down its length; (10) three unique mutations in the MC1R alignment: position 264 C instead of T, position 508 G instead of A, position 562 G instead of C; (11) one unique mutation in the c-mos alignment in position 202 C instead of G (see Appendices 5, 6).
