East Africa, Sri Lanka.

This species was reported from East Africa (Edmunds, 1971) and identified with Eliot's description of Chromodoris vicina Eliot, 1904, with which it agrees almost exactly. However there would appear an earlier name, Doris tennentana Kelaart, 1859, from Sri Lanka (Ceylon).
In specimens for Tanzania the underside is white with a marginal row of blackish purple spots and a submarginal row of yellow spots.
In a earlier publication (Rudman, 1987) I considered that Chromodoris cavae Eliot, 1904, was also a synonym of C. tennentana, but a photo sent to the Forum by Valda Fraser, from South Africa, show that it is a distinct species.
