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

The two whorls of the protoconch are deeply, obliquely immersed in the first of the succeeding turns.

The six whorls of the teleoconch are marked by two strongly elevated tuberculate keels between the sutures, the posterior one of which is about twice as wide as its neighbor.

The periphery is marked by a slender keel, while the base has two a little weaker than the peripheral one which divides the space between this and the umbilical area into three equal parts.

[4] The type specimen was found in the Pacific Ocean off Mazatlán, Mexico.
