FOUR EUROPEAN SPECIES OF PSALLUS FIEBER FOUND IN CANADA (HETEROPTERA: MIRIDAE)

Abstract

This note deals with four reddish species of European Psallus Fieber known to occur in Canada. Psallus roseus Fabricius was discovered in 1970 in British Columbia, and P. lepidus Fieber and P. jlavellus Stichel were discovered in 1976 in Nova Scotia and are now reported for the first time from the Nearctic region. They were probably introduced accidentally into this country some time ago with nursery stock. The fourth species, P. falleni Reuter, misidentified in North America as P. alnicola Douglas & Scott, is probably naturally Holarctic in distribution. The four species are redescribed, vesicae, left claspers and two adults are illustrated, and a key to separate them is provided.
