Adult female has described as follows: average length is about 2.1 to 2.3 mm. Frons convex, shiny and finely reticulate. Frons with large, scattered, deep punctures and scattered, long, erect setae. Pronotal sides are weakly arcuate, and serrations are absent. Elytra longer than pronotum. Elytral apex broadly rounded with unimpressed striae. There are small, shallow punctures on elytra. Elytral interstriae are slightly wider than striae. Elytral declivity is sloping, and weakly convex. Biology
It is considered as a high-risk quarantine pest. They show inbreeding, with the males generally mating with their sisters within the parental gallery system before dispersal. Attacked plants show signs of wilting, and branch die-back during initial stages, and later resulting shoot breakage, chronic debilitation, and sometimes sun-scorch. A polyphagous species, it is observed from wide range of host plants. They attack any woody material with abundant moisture content. Host plants
