Microglyphis perconica is a species of sea snail, a marine gastropod mollusk in the family Ringiculidae.

The spiral sculpture consists of three to five close-set, sharp, punctate grooves in front of the suture, more distant anteriorly, and a similar but more numerous and uniformly spaced series just behind the columella, behind which again are four or five widely separated similar grooves, the posterior near the periphery.

Between them and near the periphery, as well as behind it, are no grooves or but faint spiral obsolete striae.

The outer lip is straight, simple and slightly thickened.

The columella is as in Microglyphis curtula (Dall, 1890), but is less strongly twisted and with the plait and recurved margin subequal.
