Dark rings on mid- and hind-femora are similar to those of M. stigmatica, a southwestern (to South America) species which is predominantly reddish and has all its femora with black disto-median and sub-apical bands. Previous to the 1993 introduction of M. corrigiolata, the only species in our area having black disto-median and sub-apical bands on its femora was M. stigmatica.
