Originally described from Japan and later recorded from southern China, Mexichromis multituberculata was considered to differ from the other western Pacific species of Mexichromis, Mexichromis festiva, Mexichromis macropus and Mexichromis mariei in having purple spots around the edge of the mantle rather than yellow or orange. The mantle has scattered purple-tipped tubercules. However Stuart Hutchison's message suggests that Mexichromis multituberculata almost certainly includes animals with reddish, purple, blue or orange spots around the mantle edge.

Note added 20 December 2002: Animals with spots around the mantle edge, other than blue, have been moved here from the Mexichromis cf. multituberculata page.
