Diagnosis.

2.6-2.7 mm long (mean = 2.68 mm; n = 5); 2.6-2.7 × as long as wide. This species is distinguished by the elytral disc flat; declivity long, gradual; large size; declivital interstriae 2 lacking granules on declivital face; declivital face strongly shagreened, weakly impressed along striae 2 and interstriae 2; declivital strial punctures small, indistinct; posterolateral costa granulate; interstriae densely covered with long erect hair-like setae, setae longer than two interstrial widths; and striae setose, setae short, semi-recumbent, as long as strial width.

This species strongly resembles M. corporaali and is distinguished by the less strongly sulcate declivity, declivital strial punctures very large, distinct.
