Abstract

Hodostates Foerster is revised, representing the first comprehensive comparison of Nearctic and European species. Three species are recognized as valid, and the Nearctic Hodostates rotundatus (Davis) is recorded from Canada for the first time. Hodostates schaffneri Hinz is transferred to Lethades Davis, based largely on ovipositor morphology, and is redescribed. Placement in the tribe Pionini is discussed, given the presence of a deep subapical notch in the ovipositor of both New and Old World species of Hodostates. Host records for Hodostates are reviewed.

Résumé

Nous faisons une révision d’Hodostates Foerster, qui constitue la première comparaison détaillée des espèces néarctiques et européennes. Nous reconnaissons la validité de trois espèces et signalons pour la première fois la présence de l’espèce néarctique Hodostates rotundatus (Davis) au Canada. Nous déplaçons Hodostates schaffneri Hinz dans le genre Lethades Davis surtout à cause de la morphologie de l’oviscapte et redécrivons l’espèce. Nous discutons de l’inclusion des Hodostates dans la tribu des Pionini à cause de la présence, tant chez les espèces du Nouveau que de l’Ancien Monde, d’une échancrure profonde et subapicale sur l’oviscapte. Nous réexaminons la liste des hôtes d’Hodostates.
