Abstract

Four species of Tychius have been introduced into North America from Europe: Tychius picirostris (Fabricius) (host plants: Trifolium spp.), widespread in North America; T. cuprifer (Panzer) (host plants: Trifolium spp., Teline monspessulana L.), known only from Maryland, USA; T. meliloti Stephens, new North American record (host plants: Melilotus spp.), known from scattered localities in Saskatchewan, Manitoba, Ontario, and Quebec, Canada; and T. stephensi Schoenherr (host plants: Trifolium spp.), widespread in North America. Keys to separate the species are presented.

Résumé

Quatre espèces de Tychius ont été importées d’Europe en Amérique du Nord : Tychius picirostris (Fabricius) (plantes hôtes : Trifolium spp.), répandu en Amérique du Nord; T. cuprifer (Panzer) (plantes hôtes : Trifolium spp., Teline monspessulana L.), rencontré seulement au Maryland, É.-U; T. meliloti Stephens, une espèce mentionnée pour la première fois en Amérique du Nord (plantes hôtes : Melilotus spp.) et rencontrée en des points dispersés de la Saskatchewan, du Manitoba, de l’Ontario et du Québec, Canada; et T. stephensi Schoenherr (plantes hôtes : Trifolium spp.), répandu en Amérique du Nord. Des clés permettront de distinguer les diverses espèces.
