Diagnosis | Diagnosis (rustamowi): Medium-sized gecko with SVLmax up to 81 mm (less than SVLmax of T. scincus sensu stricto — 90.2 mm). Dorsal surface of body covered by rows of enlarged imbricate juxtaposed scales, in 26 – 36 longitudinal rows around the midbody and 32 – 41 transverse rows counted along the body. Enlarged scales reach occipital region. Head large and well-defined from body, covered by small granular scales. Nostril in contact with rostral, enlarged supranasal, two large nasals and first supralabial. Usually no additional subnasal scales between supralabial and naris; if such supernumerary scales present their diameter less or equal to half of naris diameter (vs. additional subnasal scales always present, their diameter about the same size as naris in T. scincus sensu stricto). Fingers and toes with fringed edges formed by large elongated triangle scales. Claws strongly compressed laterally. Small imbricate scales covering the lower surface of digits, with only a few transversely widened scales at the distal part of fingers and toes. Ventral scales of approximately the same size as dorsals. No precloacal and femoral pores. Moderate hemipenial swellings; single precloacal spur on the each side at the tail basis. Tail rounded in cross section (SVLGTailL ratio about 1.55 in T. rustamowi vs. 1.4 for T. scincus sensu stricto), tail dorsal surface covered by 11 – 18 enlarged nail-shaped scales. We failed to find any significant differences between males and females of T. rustamowi in all examined metric and meristic characters (vs. pronounced sexual dimorphism revealed for the several morphological characters in T. scincus sensu stricto: HES; OrbD; LS; FemurL; LD4A; LD4P and SVLGHES ratio) [from Nazarov et al. 2017] Additional details (4422 characters) are available for collaborators and contributors.
