Rabaglia et al. 2006: This species was considered a synonym of X. ferrugineus (Fabricius) by Schedl (1960), and is treated as such by Wood and Bright (1992). Rabaglia (2005) considered it a valid species. It is easily distinguished from X. ferrugineus by the impressed sutural interstriae, the smaller tubercles on interstriae three and the lack of denticles on interstriae 1.

Wood, 2007, general comment on Xyleborus spp.: Felled, broken, damaged, and unthrifty stems ranging in diameter from about 3 cm to more than 3 m are selected for attack. In broken or felled stems the attack may be massive and encompass most or all of the sapwood within a few days. The galleries are usually of a simple branching type that may join other similar galleries of the same species. Eggs are usually placed in clusters at or near the end of branch tunnels. The larvae feed on the mycelium of ambrosial fungi, then pupate in these galleries. The brood emerges from the parent entrance tunnels.

Browne, 1961: This fairly large shothole borer is very widely distributed. The beetle will readily infest trees in numerous plant families but it is more strongly attracted to some, notably the Urticaceae. It has been found in injured trees, dying trees, and recently cut logs. It normally infests timber of moderate to large size. The nest has a rather short entrance tunnel which soon branches at a wide angle, the branches tending to lie in one transverse plane and to follow the curvature of the log, there are no brood chambers.

Browne, 1961: This fairly large shot hole borer occurs in Malaya and Borneo, but is not very common in either of these territories. It is evidently not highly selective in its choice of hosts.
