Abstract

FERRER, M.S.; MARVALDI, A.E.  and  TOGNELLI, M.F.. First records of three species of Oxycraspedus Kuschel (Coleóptera: Belidae) in Argentina and use of a predictive model to compare their potential distribution with the range of their host-plant, Araucaria araucana. Rev. chil. hist. nat. [online]. 2007, vol.80, n.3, pp.327-333. ISSN 0716-078X.  http://dx.doi.org/10.4067/S0716-078X2007000300006.

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, 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

Keywords : Oxycoryninae; Araucaria araucana; bioclimatic variables; distribution models.
