Mitromorpha paula is a species of sea snail, a marine gastropod mollusk in the family Mitromorphidae.[1]

Description

The length of the shell attains 3.8 mm, its diameter 1.5 mm.

(Original description) The minute, solid shell consists of 4½ whorls, including a blunt protoconch of 2 whorls,. The whorls of the protoconch are convex and apparently smooth, but microscopically granular, separated by a linear suture. It ends abruptly, and from within it issue the spirals of the first spire-whorls. Perfect specimens show the granules in very close-set spiral rows. The spire whorls are slightly convex, with eight spiral lirae. The sutures are simple. The body whorl is arge, tapering anteriorly. The aperture is elongate-oval and rather widely open in front. The outer lip is simple, crenulated outside by the sculpture, slightly convex in profile, with a minute round, shallow sinus close to the suture. The inner lip is a complete narrow glaze. The sculpture shows twenty-three spiral lirae, flat-topped, half as wide as the interspaces, axially faintly incised. The colour is cinnamon-brown, lighter in a band on the prominence of the whorls.[2]

Distribution

This marine species is endemic to Australia and occurs off South Australia.
