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.
