Spurilla dupontae is a species of sea slug, an aeolid nudibranch.

[2] This species was described from two specimens collected at Stocking Island, Bahamas.

[3] Spurilla dupontae has an elongate body, tapering abruptly to the tail.

There is an ochre to brownish-green reticulate pattern and white spots all over the dorsum and cerata.

The rhinophores, oral tentacles and foot corners have the same reticulate pattern as the body.
