| Diagnosis | Diagnosis: A large member of the D. conspicillatus group (max SVL 63 mm) with a well-de- fined canthal stripe and a greatly enlarged first supralabial (first supralabial contacts ventral edge of nasal scale). Dorsal scales on trunk plate-like and markedly larger than smaller dorso- laterals. Scales on nape granular and only slightly larger than granules on side of neck. Original tail with a short to moderate, acute attenuated extension at tip; scales on dorsal surface of tail arranged in transverse rows (often in a pattern of one large row followed by two small rows; scales in the small rows * 1⁄4 the size of the scales in the adjacent large rows. Pattern variable; reticulated or with obscure transverse bands and generally incorporating numerous small pale spots. Dark pigment on crown and snout contrast markedly with pale canthal stripe and lower jaw colour which extends posteriorly as a pale bar towards the ear opening. |
