Euwallacea siporanus (Hagedorn) : Wood 1989: 173 . Xyleborus perakensis Schedl, 1942a: 194 . syn. nov. Remarks. Schedl (1970) and Wood (1989) both considered X. perakensis to be a synonym of Euwallacea wallacei . Wood (1989) also placed X. siporanus in synonymy with E. wallacei which Smith et al . (2020b) recognized as a distinct species. Images of the holotype of X. siporanus (NMNH) were compared to the lectotype of X. perakensis (NHMW) and were found to be conspecific. Distribution. ‘Borneo’, East & West Malaysia , Indonesia ( Sumatra ), Myanmar .
