Doriprismatica kyanomarginata is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae.

[2] This species was described from Egypt with additional material from The Creek, Jeddah, Saudi Arabia.

[1] Doriprismatica kyanomarginata is predominantly mottled light beige in colour.

The mantle edge is extensively folded as in other Doriprismatica and Glossodoris species with coloured lines at the edge.

There is a transition from beige to yellow, followed by a line which is pale blue and then an outer black line in this species.
