Sinezona brevis is a species of minute sea snail, a marine gastropod mollusc in the family Scissurellidae.
Distribution
This species is endemic to the North, South, and Chatham Islands of New Zealand.
Shell description
The shell is minute, white, subglobose, with a low spire and rounded whorls, strongly sculptured with rather widely spaced, sharp, oblique axials, extending from the suture to the narrow, deep umbilicus, which is margined by a sharp keel. Spiral threads between the axials are distinct only on approaching the umbilicus. The foramen is large, oval, distant from the outer lip, and at the end of a short excavated selenizone.
The shell height is up to 0.94 mm, and width 1.14 mm.
