Sinezona subantarctica is a species of minute sea snail, a marine gastropod mollusc in the family Scissurellidae.

[edit] Distribution

This species is endemic to Australia's Macquarie Islands, south of New Zealand.

[edit] Shell description

The shell is minute, white, ovate, with rounded rapidly increasing whorls, rather similar to Sinezona laevigata but with different and weaker sculpture, and a lens-shaped foramen, without a selenizone. Sculpture consists of fine spiral threads, decussed by finer and closer radial threads.

The shell height is up to 0.75 mm, and width up to 1.15 mm.
