Mexichromis macropus differs from other Australian species of Mexichromis in having a mantle border consisting of radially arranged orange or yellow-orange stripes rather than spots or longitudinal lines. The dorsum ranges from translucent white to purple and has scattered pointed papillae tipped in purple. Like, to Mexichromis festiva and to Mexichromis mariei it has often been found with a bluish grey sponge, tentatively identified as a species of Dysidea.
