polyphagous; recorded from Amoora (Meliaceae), Machilus (Euphorbiaceae), Michelia (Magnoliaceae), and Saurauia (Actinidiaceae) (Smith et al. 2020b)
The unusual morphology of this species is superficially similar to that of several other genera (see similar species above). This presents a challenge in the generic identification of specimens, especially if they are not pinned. Molecular phylogenetics revealed this species belongs in Xylosandrus and represents the only known species of an Australian species group comprised of X. monteithiDole and Beaver, 2008, X. rotundicollis(Browne, 1984b), and X. woodiDole and Beaver, 2008 in SE Asia (Cognato et al. review).
