Tornatellinops lidgbirdensis, also known as the Mount Lidgbird miniature treesnail, is a species of tree snail that is endemic to Australia's Lord Howe Island in the Tasman Sea.

The elongately conical shell of adult snails is 3.7–4 mm in height, with a diameter of 1.6–1.8 mm, with a high spire, impressed sutures and rounded whorls.

It is black and glossy with distinct growth lines.

[2] The snail occurs only at the southern end of the island, inhabiting rock faces on the summit of Mount Lidgbird and the slopes of Mount Gower.
