Xyleborinus saxesenii had previously been recorded from the ‘Samoan Islands’ in Wood & Bright (1992). This record was probably based on a single specimen in the BPBM collected on Tutuila in 1965. The specimen was examined by SMS and was determined to be a misidentified specimen of X. artelineatus . The species is widely distributed, and has been described as many different species that are now considered synonyms ( Wood & Bright 1992; Alonso-Zarazaga et al. 2017). In North America, it is one of the most common species in ethanolbaited traps. However, only one specimen was collected during this survey in American Samoa. It appears to be much more common in temperate and subtropical climates than in the moist tropics but does occur in the Hawaiian Islands, and Papua New Guinea. During this survey, Xyleborinus exiguus was the most common Xyleborinus species.
