New xyleborine (Coleoptera: Curculionidae: Scolytinae) genus with an Afrotropical-Neotropical distribution

Plant-associated arthropods have been shown to cross large oceanic distances on floating plant material and to establish themselves on distant landmasses. Xyleborini (Coleoptera: Curculionidae: Scolytinae) ambrosia beetles occur in forests worldwide and are likely capable of long range dispersal.
