Abstract

The first fully documented North American records of the Palearctic Ceutorhynchinae weevil species Amalorrhynchus melanarius (Stephens, 1831), Microplontus campestris (Gyllenhal, 1837), Pelenomus waltoni (Boheman, 1843), and Rhinoncus perpendicularis (Reiche, 1797) are presented. Characters providing for their recognition, as well as keys and habitus photographs facilitating their identification, are provided. It is likely that all four species have recently been introduced unintentionally by human activities.

Résumé

On documente ici la première mention nord-américaine des espèces de charançons paléarctiques Ceutorhynchinae suivants: Amalorrhynchus melanarius (Stephens, 1831), Microplontus campestris (Gyllenhal, 1837), Pelenomus waltoni (Boheman, 1843) et Rhinoncus perpendicularis (Reiche, 1797). On donne aussi les caractères permettant de les reconnaître, des clés de détermination, et des photographies de leurs habitus pour faciliter leur identification. Il est à peu près certain que ces quatre espèces ont été introduites de façon non intentionnelle par des activités humaines.
