Diagnosis

2.8−2.95 mm long (mean = 2.88 mm; n = 4), 1.93−2.19 times longer than wide. This species is distinguished by the elytral disc flat; elytral declivity long, gradual; all declivital interstriae uniformly granulate from base to apex; declivital face convex; posterolateral costa strongly carinate; interstriae densely covered with long, erect, hair-like setae, setae longer than two interstrial widths; striae setose, setae short, recumbent, as long as 1.5 strial widths.

This species can be distinguished from the closely related M. chrysophylli and M. corporaali by the convex elytral declivity and strongly carinate posterolateral costa.
