Taxonomy: The original reference given by Wood and Bright (1992) is incorrect. The correct reference is given above.

Biology: Strongly polyphagous (Browne 1961a, Kalshoven 1959). The gallery system often includes surface galleries and brood chambers between bark and wood, in addition to deeper galleries (Browne 1961a). Freshly sawn timber is sometimes attacked.
