Abstract. The first records of the three known species of Oxycraspedus Kuschel (Belidae: Oxycoryninae) in Argentina are reported, and added to their known distribution in Chile. These weevils are of interest because of their association with the pehuén or Monkey Puzzle tree, Araucaria araucana (Molina) C. Koch, a species of conservation concern. Their distribution data are of value for the protection of biodiversity in natural areas of Patagonia. The potential distribution of Oxycraspedus, as predicted by a model using bioclimatic variables, is coincident, as expected, with the geographic range of the araucaria host-plant.
