Akritogyra crenulata is a species of sea snail, a marine gastropod mollusk, unassigned in the superfamily Seguenzioidea.

The translucent, milky-white shell is very small and turbiniform, slightly wider than high.

The microsculpture consists of numerous close-set microscopic axial threads.

The riblets reappear on the base, crenulating the umbilical margin.

[2] This species occurs at a depth of 573–582 m on the Walters Shoals, Indian Ocean.
