Abstract

Populations of Monochamus scutellatus (Say) were found to differ morphologically from populations of M. oregonensis LeConte in color of femora, mouthparts, and antennae; elytral rugosity and shape of scutellum. The genitalia of the two entities differed slightly in the female. Alberta populations of both entities hybridized freely in the laboratory, producing a fertile F1 generation, which was successfully crossed with each parental species. Because of the lack of reproductive isolation between the allopatric entities, M. oregonensis is synonymized under M. scutellatus, but given subspecies status because of the morphological differences. Diagnostic characters of each subspecies are given.

Résumé

Relevé des différences morphologiques entre les populations de Monochamus scutellatus (Say) et celles de M. oregonensis LeConte quant à la couleur des fémurs, des parties buccales et des antennes, ainsi qu’à la rugosité des élytres et à la forme de la scutelle. Légère différence des organes génitaux externes chez la femelle des deux entités. En Alberta les populations de l’une et l’autre entité s’hybridaient librement au laboratoire, produisant ainsi une génération fertile, F1, qui se croisait avec succès avec chacune des espèces parents. Faute de différenciation des organes de reproduction entre les entités allopatriques, M. oregonensis est confondu avec M. scutellatus, mais à cause des différences morphologiques on lui assigne un statut de sous-espèce. Les caractères diagnostiques de chaque sous-espèce sont donnés.
