| Diagnosis | Description: Bauer et al. 2000: 216. Diagnosis (genus). Tropidoscincus is a member of the Eugongylus group of Greer (1979). It can be distinguished from all other genera in that group by the following combination of characters: frontoparietals fused to form a single scale; supranasals absent but a prominent postnasal suture present; lower eyelid with an obvious, centrally located semi-transparent disc; ear opening large but with moderately small lobules anteriorly; three pairs of mesosternal ribs contacting mesosternum. (Sadlier 1987) Diagnosis (aubrianus). Tropidoscincus aubrianus can be distinguished from Tropidoscincus variabilis by possessing fewer midbody scale rows (32-34 vs 36-40); more paravertebral scales (58-62 vs 49-58); scales on posterior aspect of the thighs overlapping and evenly descreasing in size ventrally whereas T. variabilis has the scales on posterior aspect of the thighs small, juxtaposed, and sharply demarcated from large overlapping scales on dorsum of thigh. Tropidoscincus aubrianus can be distinguished from Tropidoscincus rohssii by possessing fewer midbody scale rows (32-34 vs 36-40); more paravertebral scales (58-62 vs 49-56); fewer lamellae under fourth toe (32-41 vs 34-46). Juvenile Tropidoscincus aubrianus can be distinguished from juveniles of both Tropidoscincus variabilis and Tropidoscincus rohssii by the pale dorsolateral stripe being prominent in T. aubrianus posteriorly to level of the hindlimb instead of fading by middorsum (juveniIe T. rohssii and T. variabilis). (Sadlier 1987) Description (aubrianus): Sadlier 1987: 28 Diagnosis (rohssii): Sadlier 1987: 30 Description (rohssii): Sadlier 1987: 31 |
