Taxonomy: The species is listed by Wood & Bright (1992) under Coptodryas, but has the morphological characters of Microperus (Hulcr et al. 2007a), and is here transferred to that genus.

Biology: Recorded from five genera in five different families of trees, and presumably polyphagous. The gallery system (Browne 1961a) is irregularly branched in the horizontal plane with several small brood chambers elongated in the longitudinal plane. Browne (1961a) suggests that the female lays eggs in clusters over a considerable period, the offspring from each cluster occupying a separate brood chamber.
