Tympanocryptis pentalineata, also known as five-lined earless dragon, is one of a documented species of a relatively small dragon belonging to the genus Tympanocryptis.

[2] Average length is 5–6 cm (2.0–2.4 in) from snout-to-vent.

[2] The species is named for the dorsal colour pattern of the new species, characterised by five longitudinal white stripes extending along the body: one vertebral, two dorso-lateral, and two lateral.

[3][2] Tympanocryptis pentalineata occurs on flat flood-plains, covered by grasses and low perennial shrubs.

It was discovered living in crop-lands and remnant bluegrass grasslands of southeastern Queensland, which is one of the most endangered ecosystems in the state.
