Diagnosis

2.6−3.6 mm long (mean = 2.84 mm; n = 5); 2.15−2.5 times as long as wide. This species can be distinguished by the larger size, elytral declivity extremely flat and broad; especially laterally; posterolateral declivital margin elevated and carinate; and declivital surface covered with minute star-shaped scales.
