Diagnosis.

3.4-4.8 mm long (mean = 4.26 mm; n = 5); 1.7-2.53 × as long as wide. This species is distinguished by each declivital interstriae variously tuberculate, never granulate; and red-brown color.

This species strongly resembles A. minor from which it can usually be distinguished by the larger size and the tubercles on declivital interstriae 2 distinctly larger than those of other interstriae.

Similar species.

Ambrosiodmus minor .

Distribution.

China (Guangdong, Guizhou, Guangxi, Hainan, Hong Kong*, Sichuan, Xizang, Yunnan), India (Arunachal Pradesh*, Assam, Tamil Nadu, West Bengal), Indonesia (Java, Kalimantan, Sumatra), Japan, East & West Malaysia, Myanmar, Philippines, South Korea, Sri Lanka, Taiwan, Thailand, Vietnam. Established in USA ( Hoebeke 1991; Gomez et al. 2018a).

Host plants.

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 1961b).
