Pusia microzonias is a species of sea snail, a marine gastropod mollusk, in the family Costellariidae, the ribbed miters.

Description

The length of the shell attains 9.3 mm, its diameter 4.1 mm.

(Described as Mitra microzonias) The shell shows a row of white spots so arranged as to come one on each rib, forming a chain on the centre of the body whorl.

(Described as Mitra glabra) The shell is oblong-ovate in shape, notably thick, and possesses a smooth, polished surface. It is longitudinally ribbed; these ribs are rounded in form, though they become obsolete on the body whorl. The columella is equipped with four distinct folds.

The shell is a ashy-brown, while the lower portion of the body whorl transitions into a chestnut-brown. Furthermore, the shell is encircled by a single, narrow, yellowish band.

Distribution

This marine species occurs off Fiji, Ascension Island and in many other parts of the western Pacific, from Indonesia to the Marshall Islands.
