Xyleborus nodulosus is transferred to Ambrosiophilus Hulcr and Cognato because it exhibits the diagnostic characters of the genus: anterior margin of pronotum rounded; pronotal disc lacking asperities; lateral profile of pronotal disc flat; and elytral declivity steeply rounded. Smith and Cognato (2015) confirmed the placement of this species (as A. peregrinus) in Ambrosiophilus with DNA sequence data for two genes, mitochondrial COI and ribosomal 28 S. In addition to the USA, A. nodulosus occurs in China (Chongquing, Fujian [type locality], Sichuan) and Indonesia (Kalimantan) (Browne 1980). It was reported from imported timber in Japan, but no further records from Japan have been reported (Ohno 1990). Little is known about the species in its native range. However, it was recorded from three genera of Dipterocarpaceae, Octomeles Miq. (Tetramelaceae), and Pometia J. R. Forst. & G. Forst. (Sapindaceae) (Browne 1980; Ohno 1990) and is presumably polyphagous. This note underscores the importance of taxonomic research of large-scale regional faunas and its financial support. Creating comprehensive identification keys are not possible without funding for consolidating dispersed type material, production of images, and taxonomic expertise. We hope that our forthcoming key will aid the identification of future exotic introductions from Southeast Asia.	en	Smith, Sarah M., Beaver, Roger A., Cognato, Anthony I.
