Abstract

Five weevil species reared or collected from Amaryllidaceae in the New World are compared with morphologically similar weevils, mostly found on orchids. Based on preliminary analyses of external and some internal characters, they are referred to Stethobaris LeConte and described as Stethobaris cerpheroides Prena and O'Brien, new species; Stethobaris hybrisPrena and O'Brien, new species;Stethobaris nemesis Prena and O'Brien, new species; Stethobaris sprekeliae Prena and O'Brien, new species and Stethobaris ultimaPrena and O'Brien, new species. Central Mexico is their likely origin, but nearly all available specimens have been found elsewhere associated with plants traded among growers. Stethobaris nemesis is adventive in the southeastern United States (Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi and Texas) and Barbados, Lesser Antilles. Cerpheres rufescens Champion is transferred to Stethobaris (new combination), and a lectotype is designated for this species. Cerpheres glabrescens Champion and Ovanius conicollis Casey are recorded newly for Colombia, South America.
