The Western Indian Ocean M. ayliffe differs from its Pacific sister species M. mimicus in number of lateral-line scales, several morphometric features,
the position of the conspicuous bluish dorso-midlateral body stripe in relation to the lateral line, and the width of the yellow mid-lateral body stripe.
