Taxonomic history

Xyleborus corporaali Eggers, 1923: 210.

Coptodryas corporaali (Eggers): Wood and Bright, 1992: 823.

Microperus corporaali (Eggers): Hulcr, 2010: 111

Diagnosis

2.55−2.9 mm long (mean = 2.72 mm; n = 5); 2.5−2.9 times as long as wide. This species is distinguished by the elytral disc flat; elytral 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; striae setose, setae short, semi-recumbent, as long as strial width.

This species strongly resembles M. chrysophylii and can be distinguished by the more strongly sulcate elytral declivity and declivital strial punctures small, indistinct.
