Other distribution: From India through Southeast Asia and Indonesia to Taiwan and Japan in the North, and to New Guinea and the Pacific islands in the East. Intercepted in Japan in imported timber. (4)

Taxonomy: As considered by Hulcr and Cognato (2010, 2013), this is a very variable species morphologically, and its limits are not entirely clear. Molecular studies may indicate that several species are included.

Biology: Polyphagous. The gallery system has a few branches more or less in one transverse plane with several small brood chambers extending longitudinally. Surface galleries between the phloem and sapwood may occur in thick-barked stems ( Browne 1961a).
