Head, hair color at vertex, including all hairs seen to be no farther laterally than the inner rim of the compound eyes when looking at the specimen head-on
 Hairs a mixture of dark and pale (4)
 Hairs entirely pale, off-white to yellow (2)
M. marginella vs. M. taurea - CAREFUL, preservation may alter hair appearance
 M. marginella - Head, facial hair between the antennae and ocelli with strong orange highlights below the black hairs nearer to the ocelli, these highlights also present elsewhere on the face - Often but not always with significant orangish-brown highlights present medially in the tergal hair bands, with the lateral ends of the band often a distinctly lighter white color - Distribution is primarily from Mexico to the south, it is likely that it does not extend any further North than the subtropical areas of South Texas (2)
 M. taurea - Head, facial hair between the antennae and ocelli with white or only very slightly off-white hairs present below the black hairs nearer to the ocelli, no orange highlights present on the face - Hair bands always a very light white to slightly off-white color - Distribution entirely North of Mexico, although some reports of the species in Texas exist it is very unlikely that they reach past the Eastern-most fringes of the state, likely never making it to the subtropical Southern region of Texas (2)
