flat; elytralelytral:
pertaining to the elytra
declivitydeclivity:
downward slope of either the pronotum or elytra
long, gradual; all declivitaldeclivital:
pertaining to the elytral declivity
interstriae uniformly granulategranulate:
pertaining to a coarse, grainy surface texture
from basebase:
point or edge closest to the body; opposite of apex
to apexapex:
point or edge furthest from the body; opposite of base
; declivitaldeclivital:
pertaining to the elytral declivity
face convexconvex:
appearing rounded
; posterolateralposterolateral:
relating to end of the side part/portion
costacosta:
elevated ridge that is rounded at its crest, not necessarily with sharp appearance
strongly carinate; interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.

, hair-like setaeseta:
small hair-like or scale-like structure
, setaeseta:

longer than two interstrial widths; striaestria:
punctures in rows, which may or may not be impressed to make grooves
setose, setaeseta:
small hair-like or scale-like structure

pertaining to setae that are flat against the cuticle
, as long as 1.5 strial widths.

This species can be distinguished from the closely related M. chrysophylli and M. corporaali by the convexconvex:
appearing rounded

downward slope of either the pronotum or elytra
and strongly carinate posterolateralposterolateral:
