Diagnosis

3.5−4.2 mm long (mean = 3.73 mm; n = 5); 2.1−2.3 times as long as wide. This species can be distinguished by the presence of more than three spines on each elytral margin. Declivital armature consists of two large spines closest to suture on declivital summit and many smaller, uniform-sized denticles on declivital margin.

Host plants

Remarks
