Anacithara robusta is a species of sea snail, a marine gastropod mollusk in the family Horaiclavidae.

(Original description) The small, solid shell has a biconical shape.

Very many and close spiral threads overrun both ribs and interstices.

Two spirals, larger and wider spaced than the rest, traverse the periphery and ascend the spire.
