DiagnosisDiagnosis. A species of the Cnemidophorus ocellifer group with granules in the supraorbital semicircles, and no anal spurs in males. Cnemidophorus cyanurus differs from C. ocellifer, C. mumbuca, C. jalapensis, and C. con- fusionibus by having 31–38 (x= 34.5) femoral pores (a maximum of 20 in all other species); 8–10 longitudinal rows of ventral scales (6–8), 29–33(x= 30.4) transverse rows of ventrals (a maximum of 29 in all other species), 6– 7 superciliaries (always 5), 1–2 row of spurs in the heel in males (absent), one row of distinctive enlarged scales in the arm (2–4, never enlarged), no enlarged scales in temporal region posterior to third subocular (present), vertebral stripe present (absent), lateral spots absent (present), and bluish-green tail (brown tail). C. cyanurus differs from C. abaetensis by having 31–38 (x= 34.5) femoral pores (27–31, x= 24), 190–215 (x= 201.8) dorsal scales (210–240, x= 221.8), second supraocular totally separated from frontal by supraocular granules (second supraocular contacts frontal), four supraoculars (usually 3), stripe on the tail absent (present). Cnemidophorus cyanurus differs from C. littoralis by having 31–38 (x= 34.5) femoral pores (28–36, x= 32.6 in C. littoralis), 190–215 (x= 201.8) dorsal scales (168–191, x= 174.9), frontonasal never divided (35.6 % of individuals with a divided frontonasal, according to Rocha et al., 2000), second supraocular separated from frontal by supraocular granules (second supraocular con- tacts frontal), and tail stripe absent (present). Cnemidophorus cyanurus differs from C. venetacaudus by having 31–38 (x= 34.5) femoral pores (34–45, x= 38 in C. venetacaudus), 26–31 (x= 28.6) fourth toe lamellae (30–35, x= 33), vertebral and lateral stripes present (absent), and body color blue gray (brown). 
CommentCnemidophorus cyanurus, shares with the species of the ocellifer subgroup of C. littoralis (C. abaetensis, C. littoralis and C. venetacaudus), a bluish green tail, spurs on the heels of males, 6–7 supraciliaries, a high number of femoral pores (27–45), a row of enlarged scales in the dorsal part of the humerus, and 8 to 10 rows of ventral scales. 
EtymologyThe specific epithet, cyan, is a Latin adjective meaning ‘‘bluish,’’ and the Latin superlative suffix urus, means ‘‘tail’’ in allusion to the characteristic ‘‘bluish tail’’ in members of this species.
