Other distribution: From India through Southeast Asia and southern China to Taiwan, Japan and Korea in the North, and to the Philippines and Indonesian islands West of Wallace’s line in the South, but no previous records found for Thailand. Established but apparently not invasive in the U.S.A. ( Haack 2006). (4)

Taxonomy: This species is doubtfully distinct from Ambrosiodmus minor (Stebbing) . Maiti & Saha (2004) give distinguishing characters, but various combinations of these characters occur in Thai specimens, and the size ranges of the two species nearly overlap. We have retained both species in this paper pending further study of specimens from a wider geographical range.

Biology: The species is polyphagous, but may show some preference for Dipterocarpaceae in the southern part of its range, and for Fagaceae in the northern part ( Browne 1961a).
