Euwallacea andamanensis (Blandford) : Wood 1989: 172.

E. andamanensis sensu Wood & Bright (1992) is a complex of several species and needs revision ( Cognato et al. 2020). At this stage of the study, we can only record the presence of a species of the complex in Bhutan. Its assignment to a particular species must await further study.

New records. Bhutan, Gedu, 6.xiii.[19]85, BG Padgham, ex Trewia nudiflora, CIE A 17491 (3, NMHL); as previous except: DE Padgham (2, NHML).

Distribution. Bangladesh, Bhutan, China ( Hong Kong, Jiangxi, Yunnan), Federated States of Micronesia, India (Andaman Is, Assam, Bihar, Madhya Pradesh, Maharashtra, Meghalaya, Tamil Nadu, West Bengal), Indonesia (Buru I., Java, Mentawai Is, Sumatra), Japan, Laos, East & West Malaysia, Myanmar, New Guinea, Thailand, Vietnam.

Biology. The species in the complex are polyphagous ( Beeson 1930; Browne 1961), but Mallotus (= Trewia ) nudiflorus ( Euphorbiaceae ) has not been recorded previously as a host tree. The gallery system is briefly described by Browne (1961), and resembles that of other species of Euwallacea ( Smith et al. 2020) .
