Megastomia conoidea is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.

The shell size varies between 2.5 mm and 7 mm. The white shell is solid, polished and with microscopic growthlines. The periphery is more or less distinctly keeled or angulated, with an impressed spiral line. There are eight, nearly flat whorls. The umbilicus is small and deep. The columellar tooth is strong and prominent. The interior of the outer lip is ridged, terminating in small tubercles within the mouth.
