Dysthaeta naevia is a species of beetle in the family Cerambycidae. It was described by Olliff in 1888. It is known from Norfolk Island.[1][2]

Description

Dysthaeta naevia adults are 15-17 mm in length and moderately convex in shape. Overall, they are dark in colour with pubescence on the head, antennae, prothorax, scutellum, underside and legs.[3]

The head has a strongly marked median line. The antennae are about as long as the body, dark, and with grey pubescence on segments 3-11.[3]

The prothorax is transverse in shape, and has a pair of tubercles laterally and a second pair dorsally. The scutellum is rounded posteriorly. The tibiae of the legs are dark basally.[3]

The elytra at their bases are much wider than the prothorax, but become narrower posteriorly. Each elytron has a conspicuous tubercle in the middle near the base (distinguishing it from the related D. anomala). The basal halves of the elytra are coarsely and sparsely punctured, becoming almost impunctate posteriorly.[3]
