Important pest with worldwide distribution, originated from Southeast Asia. Known from Hungary by two specimens reared from bamboo imported from Indonesia.
Elongate species, elytra almost 2× longer than pronotum. Body unicoloured dark or bicol- oured. Apical declivity of elytra without spines, with keel on suture.
More robust species, elytra about 1.5× longer than pronotum. Pronotum black, elytra red- dish-brown. Apical declivity of elytra with two bigger and few smaller spines.
Body bicoloured. Anterior part of pronotum and posterior part of elytra black, posterior part of pronotum and anterior part of elytra reddish. Frons with long, erected, yellow setae. Last antennomere nearly as long as two preceding combined. 3–4 mm.
Since its first record in Hungary (Merkl 1998) it was found in many localities. Polyphagous species, larvae develop in grapevine, fruit trees and ornamental trees.
