Photographed on “Coral Garden” off Eriyadu Island Resort, this relatively uncommon species of Chromodoris seems to be restricted to the Indian Ocean and widely distributed in Sri Lanka and subsequently from Tanzania and the Maldives.
From its colour pattern, it seems to be a sibling species of the western Pacific species Chromodoris coi. In C. glenei, the central part of the mantle is an orange-brown colour with deep purple or black markings. In C. coi the central region is a dull brown colour with a darker mottling of the same color. In both species there is a very similarly shaped wavy edge to the central region of the mantle and in both species the mantle margin consists of an inner dull purple band and outer white band.
