Description

The Border Thick-tailed Gecko is a small lizard up to 10 cm long (average 7 cm). It is fawn to brown above with faint darker brown flecks and many small white spots arranged in rows across the head, back and sides and on the legs. The gecko looks 'knobbly' due to numerous conical tubercles, especially on the tail. The tail is fat and rectangular with a thin tapering tip, and typically has four pale rings. The species has recently been re-assigned to the genus <em>Uvidicolous</em>.

Distribution

Found only on the tablelands and slopes of northern NSW and southern Queensland, reaching south to Tamworth and west to Moree. Most common in the granite country of the New England Tablelands. Occurs at sites ranging from 500 to 1100 m elevation. Populations are mostly fragmented, with over 50 discrete sites currently known that are separated by at least 2 km.

Habitat and ecology

  • As implied by another of its common names (Granite Thick-tailed Gecko), this species often occurs on steep rocky or scree slopes, especially granite. Recent records from basalt and metasediment slopes and flats indicate its habitat selection is broader than formerly thought and may have extended into areas that were cleared for agriculture..
  • Favours forest and woodland areas with boulders, rock slabs, fallen timber and deep leaf litter. Occupied sites often have a dense tree canopy that helps create a sparse understorey.
  • These Geckos are active at night and shelter by day under rock slabs, in or under logs, and under the bark of standing trees.
