Iredalea theoteles is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.

This very small shell has some slight resemblance to Mangilia thepalea Melvill & Standen, 1896 (a taxon inquirendum).

The nodulous papillae are, however, much larger in proportion to the size of the shell, and, in consequence, fewer.

The four rows—two on the penultimate, two on the last whorl—are approximate, and the space contained by them is banded with ochre, the white shining nodules standing out more prominently.
