Taxonomy: We have compared the female holotype of D. multiporus (NMW) and the male lectotype of D. decemspinatus (NMW) directly with a long series of male and female specimens collected by S. Adebratt in East Malaysia (Sabah) (ZMLU, RAB), in which the sexes can be reliably associated. Schedl (1942) already suggested that the male of D. multiporus might be D. decemspinatus , and this can now be confirmed. The species is closely related to G. papuanus .

Distribution: The species occurs in East and West Malaysia and in the Philippines and has been imported in timber to Japan. Its occurrence in Vietnam ( Schedl 1972a) needs to be substantiated.

Biology: Recorded hosts are all in the family Dipterocarpaceae ( Anisoptera , Shorea , Vatica ) ( Browne 1961a, 1985; Ohno et al. 1988).
