Variation.

Body length: 6.9-7.6 mm, length of elytra: 5.1-5.8 mm, width: 4.0-4.6 mm. Female has the antennal club composed of three lamellae, short, as long as the remaining antennomeres combined; eyes as large as those in male.

Etymology.

The new species is named after its type locality, Damaidi.
