Taxonomy. We have examined the male holotype (BMNH). The female has not been described. The species is closely related to G. pendleburyi and distinguishable by little more than its greater size and the relative lengths of the spines (see key to males). It is possible that further collections will show that it overlaps in these characters with G. pendleburyi . The female is expected to be very similar to G. pendleburyi and will probably run to the same couplet in the key to females.

Distribution: Intercepted in Japan in timber imported from 'various shipment localities' in Borneo ( Ohno 1990b) and from Indonesia (Sumatera) ( Ohno et al. 1986).

Biology: Recorded from four genera of Dipterocarpaceae ( Anisoptera , Dipterocarpus , Dryobalanops , Shorea ), with nearly 3,000 specimens obtained from Dipterocarpus sp. , and as single specimens from Dyera sp. (Apocyanaceae) and Tarrietia sp. (Sterculiaceae) ( Ohno 1990b). The latter two genera are unlikely to be normal hosts.
