Abstract

A molecular and biometric assessment and redescription of Myzodium mimulicola (Drews and Sampson) are provided. New North American host and distributional data are presented, including the first record from Alaska. Myzodium knowltoni (Smith and Robinson) is a junior subjective synonym of M. mimulicola, based on molecular-sequence and morphological evidence. A key to the known Myzodium species (apterae and alatae) is included.

Résumé

Nous présentons une évaluation moléculaire et biométrique, ainsi qu’une redescription de Myzodium mimulicola (Drews et Sampson). De nouvelles données sur la répartition en Amérique du Nord et sur les hôtes sont fournies, dont une première mention pour l'Alaska. L’étude de la morphologie et des séquences moléculaires montre que Myzodium knowltoni (Smith et Robinson) est un synonyme subjectif plus récent de M. mimulicola. Un clé permet de reconnaître les espèces connues de Myzodium (aptères et ailées).
