Microgaza rotella is a species of sea snail, a marine gastropod mollusk in the family Solariellidae.

The remainder of the whorls show a narrow puckered band revolving immediately below the suture, on which the shell matter is as it were pinched up into slight elevations at regular intervals, about half a millimeter apart.

The remainder is smooth, shining or with evanescent traces of revolving lines impressed from within and strongest about the rounded periphery.

The base of the shell is rounded toward the umbilical carina over which it seems to be drawn into flexuously radiating well-marked plications (about thirty-two on the last turn).

The shell shows zigzag brown lines variously transversely disposed and disappearing on the base.
