Distribution
China (Hong Kong), East & West Malaysia, Japan, Thailand, Vietnam
Host plants
recorded from five genera in five different families of trees, and presumably polyphagous (Beaver et al. 2014Beaver et al. 2014:
Beaver RA, Sittichaya W, Liu L-Y. 2014. A synopsis of the scolytine ambrosia beetles of Thailand (Coleoptera: Curculionidae: Scolytinae). Zootaxa 3875: 1-82. http://dx.doi.org/10.11646/zootaxa.3875.1.1)
Remarks
Browne (1961a) suggests that the female lays eggs in clusters over a considerable period, the offspring from each cluster occupying a separate brood chamber.
