may well be a different species
M. signata Champion, 1891 described as black, probably including the tibial spurs,
with white markings on head and pronotum, the latter with three, not four dark streaks.
This mesoamerican form can be seen on iNaturalist.

north-of-Mexico findings of M. signata (sensu Liljeblad, 1945, AZ) differ from the Champion species
in having brown elytra, pallid tibial spurs, and the pronotum without definite pattern.
Example:


Note the elytral fascia being considerably more posteriour in position in the Texas, than in the AZ Mordellid.
Note also streak of white hair along suture.

signata, as described by Liljeblad
I can't find Champion's original description, but Liljeblad describes signata as "head black, prothorax black, elytra with ground ferruginous, darker toward apex" (along with descriptions of the markings). Matches this one exactly (and the other that was moved from signata)

Thanks,
Tim
