|Diagnosis||Diagnosis. Body size moderately large (to 68 mm SVL) with long tail (1.8–2.7 × SVL). Gular and scapular folds absent; post-auricular fold absent or weak. Scales in axilla not granular. Lacks spinose scales on thighs or neck. Pre-cloacal pores 4; femoral pores 0 [MELVILLE et al. 2019: 32].|
Comparison. Overlaps geographically with D. australis, D. nobbi and D. carpentariensis sp. nov. It differs morphologically from both D. australis and D. nobbi in lacking a gular fold. Also differs from D. nobbi in being smaller in body size (65 mm vs. 75 mm SVL), lacking spinose scales on the thighs or neck, having fewer pre-cloacal pores and lacking femoral pores. It differs from D. carpentariensis sp. nov. in that it lacks a scapular fold, scales in axilla are not reduced in size and not granular, scales on flanks strongly heterogeneous with scattered scales that are distinctly larger than surrounding scales, and a black gular band or black spots on sides of neck [MELVILLE et al. 2019: 32].
|Comment||Synonymy after MELVILLE et al. 2019 who revalidated Grammatophora jugularis from the synonymy of D. bilineata.|
